What is the Avalue APC-21WMX?

The APC-21WMX is a slim, fanless industrial Panel PC from Avalue's APC series. It uses a MediaTek MT8391 processor with 4GB onboard RAM and 64GB UFS storage, runs Android 15, and has a 1920 x 1080 IPS panel with projective capacitive multi-touch. The same platform is also offered as the APC-24WMX and APC-32WMX in larger sizes.

Which screen sizes are available in this family?

The family has three models: the APC-21WMX with a 21.5 inch panel, the APC-24WMX with a 23.8 inch panel and the APC-32WMX with a 32 inch panel. All three use an IPS panel at 1920 x 1080 resolution. Brightness, contrast, response time, dimensions, weight, VESA pattern and adapter rating differ by size, so choose the size that fits your enclosure or wall space.

What processor does the APC-21WMX use?

It uses the MediaTek MT8391, which combines a hexa core Cortex-A55 cluster with a dual core Cortex-A78 cluster. Graphics come from a Mali-G57 MC2 that supports OpenGL ES 1.1/2.0/3.2, Vulkan 1.1 and OpenCL 1.1, 1.2 and 2.0. It is an Arm based platform, not an x86 one, so software must target Android.

How much memory and storage does it have?

The APC-21WMX has 4GB of onboard RAM and 64GB of onboard UFS storage. Both are soldered to the board, and the specification lists no SO-DIMM, M.2 or SSD bay for upgrades. If your application needs more data space, use external storage over the USB ports or network storage, and confirm your needs with TSL before ordering.

Which operating system does the APC-21WMX run?

The specification lists Android 15 as the supported operating system. Windows and standard Linux distributions are not listed for this model. It suits applications written as Android apps or those that run in an Android browser. If you must run Windows based software, a x86 panel PC such as the APC-2138 is the better match.

What are the display specifications?

The panel is an IPS LCD at 1920 x 1080 resolution with an ELED backlight and a viewing angle of 89 degrees in all four directions. The 21WMX is rated 350 cd/m2 with a 3,000 contrast ratio and 18ms response time. The 24WMX and 32WMX are rated 300 cd/m2 with a 1,000 contrast ratio.

What kind of touchscreen does it have?

It has a projective capacitive (PCAP) touchscreen that supports multi-touch with up to 10 points. PCAP touch gives the smooth, tablet-like response that users expect for kiosks, signage controls and operator terminals. The specification does not list an IP rating for the front panel, so check with TSL if your site needs protection against dust or liquid.

Does the APC-21WMX have Ethernet?

Yes. It has one RJ45 port with a Realtek RTL8111HS controller, compatible with 10/100/1000 Base-Tx Gigabit Ethernet. The same port can also receive power when you use the Powered LAN option (IEEE 802.3bt), which lets one network cable carry both data and power to the panel PC in suitable installations.

Which USB ports are provided?

The external I/O offers one USB 3.0 port, one USB 2.0 port and one USB Type-C port. The Type-C port is USB 3.2 Gen 1 and supports data and OTG/ADB. A USB Type-A to Type-C cable is included in the packing list, which is useful for connecting a host computer for app loading and debugging.

Can the APC-21WMX output video to another monitor?

The specification lists one HDMI-in port, which is an input, and no video output connector. It is therefore intended as a standalone touch display computer rather than a source that drives an extra screen. If your design needs a second display output, discuss alternatives with TSL before choosing this model.

Does it support Wi-Fi and Bluetooth?

Wireless is optional. The specification lists optional Wi-Fi 802.11b/g/n/a/ac/ax and optional Bluetooth 5.2. Because these are options, state in your enquiry that you need wireless so TSL can quote the right configuration. Where a wired link is preferred, the onboard Gigabit Ethernet port is always available.

What camera does it include?

It supports one MIPI 8.0MP camera under the Data Collection features. This suits applications such as video calls, visitor check-in, QR or code scanning inside an app, and simple image capture. Confirm the exact camera fitment, such as mounting position and lens, with TSL for your configuration, as the specification gives only the interface and resolution.

Does the APC-21WMX support NFC?

Yes. The NFC feature supports 13.56MHz and the standards ISO/IEC 18092, ISO/IEC 21481, ISO/IEC 14443 A and B, ISO/IEC 15693, JIS X 6319-4 and MIFARE. This lets the panel PC read compatible cards and tags for access control, staff identification, attendance and self-service workflows without a separate reader.

What audio features are available?

It has a standard quad microphone array that supports noise reduction and echo cancellation, plus built-in speaker output of 2 x 4Ω 5W. This combination suits voice calling, announcements, intercom style use and spoken prompts at kiosks or reception points, without needing separate audio hardware for basic use.

What power input does it need?

The panel PC runs from +12V DC through a DC jack. The supplied AC-DC adapter takes 100 to 240Vac at 50 to 60Hz and delivers 36W (12V at 3A) for the 21WMX, 48W (12V at 4A) for the 24WMX or 60W (12V at 5A) for the 32WMX. A power cord is included in the packing list.

Can the APC-21WMX be powered over Ethernet?

Yes. The specification lists Powered LAN (IEEE 802.3bt) as an alternative to the DC adapter. This can reduce cabling at a mounting point because one network cable supplies data and power. You need a compatible 802.3bt power source on the network side, so plan your switch or injector accordingly.

What is the operating temperature range?

The operating temperature is 0°C to 40°C (32°F to 104°F), and the storage temperature is -20°C to 60°C (-4°F to 140°F). Operating humidity is 20 to 80% RH. These figures suit indoor environments such as offices, retail floors, hospitals and control rooms, but not outdoor or very hot sites.

Is the APC-21WMX fanless?

Yes. The system fan entry is Fanless, so the unit has no moving cooling parts, which keeps it quiet and avoids dust being pulled through a fan. The housing is plastic ABS. Allow reasonable airflow around the unit when mounting it and stay within the rated 0°C to 40°C operating range.

How do I mount the APC-21WMX?

A wall mount bracket is supplied, along with screws, wall plugs and a spirit level to help install it straight. The unit also has a VESA pattern: 75 x 75mm on the 21WMX and 100 x 100mm on the 24WMX and 32WMX. Choose a VESA arm or stand that matches the pattern of your model.

What are the dimensions and weight?

The 21WMX measures 506.9 x 305.4 x 32.2 mm and weighs 3.5kg. The 24WMX has the same listed dimensions and weighs 3.8kg. The 32WMX measures 735.6 x 436.2 x 36.5 mm and weighs 7.7kg. The slim depth of about 32 to 37 mm helps in tight wall or enclosure installations.

What is included in the box?

The packing list has one panel PC, one 12V adapter (3A, 4A or 5A by model), one power cord, one USB Type-A to Type-C cable, one wall mount bracket, 5 KA4.0*3mm screws with wall plugs, 2 M4.0*46mm screws, 4 EVA cotton pieces and one spirit level.

How does AT/ATX power mode work on this model?

The specification lists AT/ATX power modes, with AT as the default. In AT mode a panel PC normally starts as soon as power is applied, which is handy for unattended signage or kiosks that must recover after a power cut. The panel also has Power, Volume Up and Volume Down buttons for local control.

What applications is the APC-21WMX suited to?

Its Android 15 platform, PCAP touch, NFC, camera, microphones and speakers suit interactive terminals such as digital signage, self-service kiosks, smart retail, visitor and room management, and wall mounted control screens. Final suitability depends on your software, so test your Android app on the panel before large rollouts.

Can I add expansion cards to the APC-21WMX?

The specification lists no internal expansion slots, SO-DIMM sockets or drive bays. Connectivity is expanded through the external ports instead: USB 3.0, USB 2.0, USB Type-C, Gigabit Ethernet and optional Wi-Fi and Bluetooth. If you need M.2, PCIe or drive bay expansion, look at an x86 panel PC such as the APC-2138.

How does the APC-21WMX compare with the APC-2138?

Both have a 21.5 inch, 1920 x 1080 PCAP touch, fanless design. The APC-2138 is x86, with an 11th Gen Intel Core processor, Windows, SO-DIMM memory, M.2 and a 2.5 inch SSD bay. The APC-21WMX is Arm based with Android 15, fixed 4GB RAM and 64GB UFS, 12V input, NFC and a camera.

Does TSL Automation Solutions supply and support the APC-21WMX in India?

Yes. TSL Automation Solutions is an authorised India distributor of Avalue and supplies and supports the APC series.
