How much memory and storage does the SID-21WR5 have?

The unit ships with 8GB of onboard RAM and 64GB of onboard eMMC storage, both fixed at the factory rather than user-upgradeable. This is more than double the 2GB RAM and 32GB eMMC found on the earlier SID-21WR2, giving the SID-21WR5 noticeably more headroom for running Android applications, browser-based kiosk software and digital signage content simultaneously without slowing down.

Can I expand the storage on the SID-21WR5?

The 64GB eMMC storage is soldered onboard and not user-expandable, but the unit includes an external SD card slot that supports cards up to 64GB, which can be used for additional data, media or content storage. There is no listed provision for adding an internal SATA drive or M.2 SSD, so any expansion needs to go through the SD slot or external USB storage.

What operating system does the SID-21WR5 run?

The SID-21WR5 ships with Android 12 pre-installed, giving it a familiar touch-first interface suited to kiosk, signage and interactive display applications. Unlike the earlier SID-21WR2, which offered a choice between Android 11 or Debian 11, the SID-21WR5's specification lists Android 12 only, so customers planning a Linux-based deployment should confirm availability with TSL before ordering.

What display and touch technology does the SID-21WR5 use?

It features a 21.5 inch panel with a 1920x1080 Full HD resolution, 250 cd/m2 luminance and an 800:1 contrast ratio, with a viewing angle of 85 degrees on all four sides. Touch input is handled by a projected-capacitive (PCAP) panel supporting up to 10-point multi-touch, making it responsive for finger-based interaction in kiosk and signage deployments.

How does the SID-21WR5 display compare with the SID-21WR2?

Both panels are 21.5 inch Full HD (1920x1080) PCAP 10-point multi-touch displays, but the specifications differ on contrast: the SID-21WR5 lists an 800:1 contrast ratio and 250 cd/m2 luminance, while the SID-21WR2 is rated at a higher 3000:1 contrast. Customers who need the deepest blacks or highest contrast for signage content should factor this into their choice between the two models.

What GPU does the SID-21WR5 use and what does it support?

Graphics are handled by the Mali-G610 MC4 GPU, which supports OpenGL ES 1.1/2.0/3.1/3.2, Vulkan 1.2 and OpenCL 1.1/1.2/2.0. This gives the SID-21WR5 solid support for modern Android UI rendering, hardware-accelerated video playback and lightweight graphics-based kiosk or signage applications without needing a discrete graphics card, keeping the design compact and fanless.

What network and wireless connectivity does the SID-21WR5 offer?

It includes a wired 10/100/1000 Base-Tx Gigabit Ethernet port via RJ45 for stable network connections, plus onboard Wi-Fi 802.11b/g/n/a/ac/ax and Bluetooth 5.2 for wireless connectivity. This combination lets integrators choose a wired connection for reliability in fixed kiosk installations, or rely on Wi-Fi and Bluetooth for more flexible signage or mobile-adjacent deployments.

What USB ports are available on the SID-21WR5?

The unit provides one USB 3.0 port, two USB 2.0 ports, two USB ports wired for serial communication at TTL level, and one USB Type-C port supporting USB 3.2 Gen 1 data, OTG/ADB and DisplayPort Alt Mode. This mix covers peripherals like scanners, printers and storage devices, plus development and debugging over Type-C.

Does the SID-21WR5 have a camera?

Yes, it includes a built-in 5.0MP camera, which can be used for applications such as basic image capture, QR or barcode scanning through software, or simple video calling within kiosk and signage deployments. This is an addition over the SID-21WR2 specification, which does not list an onboard camera.

What audio features does the SID-21WR5 include?

The panel PC has a built-in microphone and two 3W speakers for onboard audio playback and capture, along with a 3.5mm earphone/microphone combo jack for connecting a headset or external audio equipment. This is enough for voice prompts, notification sounds and basic two-way audio in interactive kiosk applications without needing external speakers.

What is the operating temperature range of the SID-21WR5?

The SID-21WR5 is rated to operate from 0°C to 40°C (32°F to 104°F), with a wider storage temperature range of -20°C to 60°C (-4°F to 140°F) when not powered on. Operating humidity is specified at 20 to 80% relative humidity, which is typical for indoor kiosk and signage environments rather than harsh outdoor conditions.

Is the SID-21WR5 suitable for harsh or outdoor environments?

Based on the published specification, the SID-21WR5 is built with a Plastic ABS enclosure and does not list an IP rating, unlike the SID-21WR2, which has a metal chassis with an IP65-rated front panel. This makes the SID-21WR5 better suited to indoor kiosk, signage and office-type environments rather than dusty or wet industrial settings.

What power supply does the SID-21WR5 require?

The unit runs on a +12V DC input delivered through a DC jack, and is supplied with a 36W (12V at 3A) AC-DC adapter that accepts 100 to 240Vac at 50 to 60Hz. Power mode can be set to AT or ATX, with AT as the factory default, giving integrators flexibility over how the unit powers on.

Is the SID-21WR5 fanless?

Yes, the SID-21WR5 uses completely fanless cooling, relying on its Plastic ABS enclosure and internal design to dissipate heat from the Rockchip RK3588 processor across its rated 0°C to 40°C operating range. Fanless operation removes moving parts that can wear out or draw in dust, which helps reduce maintenance in continuously running kiosk and signage installations.

Can the SID-21WR5 be wall or arm mounted?

Yes, it includes a 100 x 100mm VESA mounting pattern on the rear, which is compatible with standard VESA wall brackets, arm mounts and kiosk enclosures. At 504.5 x 303 x 31.8mm and 3.5kg, it is light enough for most VESA arms rated for 21 to 22 inch displays without needing specialised mounting hardware.

What control buttons are on the SID-21WR5?

The unit has physical Power, Volume+ and Volume- buttons for basic onboard control, letting operators power the unit on or off and adjust the built-in speaker volume without needing to go through the Android software interface, which is useful for kiosk deployments where the touchscreen is dedicated to customer-facing content.

What is included in the box with the SID-21WR5?

Each SID-21WR5 ships with the panel PC unit itself, a 36W AC/DC adapter rated 12V at 3A, a power cord, and a USB cable with a Type-A connector on one end and a Type-C connector on the other, covering the basics needed to power on and connect the unit out of the box.

What applications is the SID-21WR5 designed for?

With its 21.5 inch touchscreen, Android 12 operating system, Gigabit Ethernet, Wi-Fi and Bluetooth connectivity, the SID-21WR5 is well suited to self-service kiosks, digital signage, retail point-of-interaction displays and general HMI-style front ends where a large, fanless, touch-enabled panel PC is needed rather than a compact embedded controller.

How does the SID-21WR5 compare overall with the SID-21WR2?

The SID-21WR5 uses the newer octa-core Rockchip RK3588 versus the quad-core RK3568 in the SID-21WR2, and offers more RAM (8GB versus 2GB) and storage (64GB versus 32GB eMMC). It adds a 5.0MP camera and 802.11ax Wi-Fi with Bluetooth 5.2, but drops the RS-232/RS-485 serial ports and IP65-rated metal enclosure that the SID-21WR2 offers, using serial-over-USB and a Plastic ABS body instead.

Does the SID-21WR5 support serial devices like scanners or printers?

It does not include traditional RS-232 or RS-485 DB9 serial ports like the SID-21WR2. Instead, it provides two USB ports wired for serial communication at TTL level, which can connect to compatible serial peripherals through a USB-to-TTL interface. Integrators using standard RS-232/RS-485 equipment should confirm compatibility or plan for a TTL-level connection before deployment.

Does the SID-21WR5 support external video input?

Yes, it includes one HDMI-in port, which allows the panel to accept a video signal from an external source such as a PC, media player or set-top box, effectively letting the 21.5 inch touchscreen double as an external monitor input in addition to running its own Android 12 applications.

Can the SID-21WR5 read external storage cards?

Yes, it has an external SD card slot that supports cards up to 64GB, which can be used to load content, transfer files or add extra storage for media used in digital signage or kiosk applications, separate from the fixed 64GB of onboard eMMC storage.

What is the weight and footprint of the SID-21WR5?

The SID-21WR5 measures 504.5 x 303 x 31.8mm and weighs 3.5kg, giving it a slim profile for a 21.5 inch panel PC. Combined with its 100 x 100mm VESA mount, this compact footprint makes it straightforward to integrate into kiosk enclosures, wall mounts or countertop stands without adding significant bulk.

Does TSL Automation Solutions provide warranty and after-sales support for the SID-21WR5 in India?

Yes, as an authorised Avalue distributor, TSL Automation Solutions supplies genuine SID-21WR5 units to customers across India along with manufacturer warranty coverage and local pre- and post-sales support. This includes helping with product selection, configuration guidance and troubleshooting, so customers are not left dealing with an overseas supplier directly for support.

Is the SID-21WR5 compatible with third-party VESA mounts and kiosk enclosures?

Yes, its 100 x 100mm VESA mounting pattern is a widely used standard, so it should fit most third-party VESA-compatible wall mounts, arms and kiosk enclosures designed for that pattern. Customers should still check the load rating and depth clearance of their chosen mount against the unit's 3.5kg weight and 31.8mm depth.

What Bluetooth version does the SID-21WR5 support?

The SID-21WR5 includes Bluetooth 5.2, an upgrade over the Bluetooth 5.0 fitted to the earlier SID-21WR2. This can be used to pair wireless peripherals such as barcode scanners, printers or audio accessories, and generally offers improved range and power efficiency compared with older Bluetooth versions.

How do I choose between the SID-21WR5 and the SID-21WR2?

Choose the SID-21WR5 if the application needs more processing power, RAM, storage, a built-in camera or the latest Wi-Fi and Bluetooth standards. Choose the SID-21WR2 instead if the deployment requires a metal, IP65-rated enclosure, RS-232/RS-485 serial ports, or the option to run Debian 11 rather than Android only. TSL can help match the right model to the application.

Who should I contact to buy the SID-21WR5 in India?

Customers in India can order the SID-21WR5 directly through TSL Automation Solutions, which stocks and supports the Avalue product range as an authorised distributor. TSL can advise on configuration, provide pricing and lead times, and offer after-sales support and warranty handling for the unit once deployed.
