What is the Avalue ECM-WCL?

The ECM-WCL is a 3.5-inch industrial single board computer from Avalue's ECM series, built around a bottom-layer soldered Intel Core Series 3 processor. It combines DDR5 memory, triple display outputs, M.2 storage and wireless expansion, dual 2.5GbE, serial I/O, and GPIO in a compact board-level form factor for embedded and industrial systems.

Which processor powers the ECM-WCL?

The ECM-WCL uses an Intel Core Series 3 processor that is soldered directly to the bottom layer of the board, rather than a socketed CPU. This gives a fixed, vibration-resistant compute platform suited to industrial environments where a removable processor is not required.

How much memory can the ECM-WCL support?

The ECM-WCL has one 262-pin DDR5 SO-DIMM socket running at 6400MHz, supporting up to 48GB. This is a single-channel memory design, so the maximum capacity is delivered through one high-density DDR5 module rather than dual modules.

Does the ECM-WCL support ECC memory?

The published specification lists a standard 262-pin DDR5 6400MHz SO-DIMM socket without mention of ECC support. For applications requiring ECC memory, contact TSL Automation Solutions to confirm the exact module compatibility before ordering.

How many displays can the ECM-WCL drive?

The ECM-WCL supports triple independent displays through one DP++ port, one HDMI port, one 2-channel LVDS or eDP channel, and a USB Type-C port with DisplayPort output. This makes it suitable for multi-monitor HMI, kiosk, and control room applications.

What is the LVDS and eDP configuration on the ECM-WCL?

The board provides one LVDS channel supporting 1920 x 1080 resolution over 2 channels at 18 or 24-bit color, or alternatively one eDP channel at 1920 x 1080 @ 60Hz over 2 lanes. LVDS is the default configuration.

What graphics chipset does the ECM-WCL use?

Display output is handled by the Intel 3rd Gen Xe cores integrated graphics, which drives the DP++, HDMI, USB Type-C DP, and LVDS/eDP outputs simultaneously for triple display operation.

What storage options are available on the ECM-WCL?

Storage is provided through an M.2 Key-M 2280 slot with PCIe Gen4 support for NVMe SSDs, and an M.2 Key-B 2242/3042/3052 slot that can also be used for a PCIe x1 SSD when not populated with a WWAN module.

What expansion slots does the ECM-WCL provide?

The ECM-WCL offers three M.2 slots: an M.2 Key-E 2230 for Wi-Fi/CNVi modules, an M.2 Key-B 2242/3042/3052 for WWAN, storage or LTE/IO cards, and an M.2 Key-M 2280 for PCIe Gen4 NVMe storage.

Does the ECM-WCL support WWAN and GNSS?

Yes. The M.2 Key-B slot supports WWAN and GNSS modules with a co-lay SIM card slot, and includes a jumper-selectable 3.3V or 3.8V module voltage setting. Only one SIM card is supported at a time.

Does the ECM-WCL support Wi-Fi?

Yes, the M.2 Key-E 2230 slot supports Wi-Fi modules along with Intel CNVi, using PCIe x1 and USB 2.0 signaling for wireless connectivity.

What Ethernet connectivity does the ECM-WCL have?

The ECM-WCL includes two Gigabit Ethernet ports at 2.5GbE, driven by an Intel I226LM controller and an Intel I226V controller, each brought out via an RJ-45 connector and supporting 10/100/1000/2.5G Base-Tx speeds.

What USB ports does the ECM-WCL provide?

The board offers 2 x USB 3.2 Gen2x1 Type-A ports plus 1 x USB 3.2 Gen2x1 Type-A and 1 x USB Type-C (15V@3A with DisplayPort 1.4a) on the dual-deck I/O, in addition to 4 x USB 2.0 available via pin header.

What serial ports and GPIO does the ECM-WCL support?

It provides four COM ports: two fixed RS-232 and two configurable as RS-232, RS-422, or RS-485, along with one 8-bit GPIO header for digital input/output in industrial control applications.

What audio capability does the ECM-WCL offer?

Audio is handled by a RealTek ALC888S-VD2-GR codec with Line-in, Mic-in, and Line-out interfaces, plus a 2 x 2W into 4-ohm amplifier for basic onboard audio output.

What operating temperature range does the ECM-WCL support?

The standard version of the ECM-WCL is rated for 0°C to 60°C (-4°F to 140°F) operation with 0.5m/s airflow, suitable for typical indoor industrial and embedded environments.

What power input does the ECM-WCL require?

The ECM-WCL accepts a DC input range of +12V to +24V and supports AT/ATX power modes, with AT set as the default configuration for industrial deployment.

Can the ECM-WCL run in ATX power mode?

Yes, the board supports both AT and ATX power modes, with AT as the default setting. This flexibility lets integrators choose the power sequencing that matches their enclosure and system design.

Which operating systems does the ECM-WCL support?

The ECM-WCL supports Windows 11 and Linux, making it suitable for a wide range of industrial control, HMI, and embedded computing software stacks.

Does the ECM-WCL include hardware security features?

Yes, it has an onboard NuvoTon NPCT760AABYX chip supporting TPM 2.0, enabling hardware-based encryption key storage and platform integrity checks for secure industrial deployments.

What form factor does the ECM-WCL use and how is it mounted?

The ECM-WCL is built on the industry-standard 3.5-inch SBC form factor, designed for board-level integration into custom embedded enclosures, panel PCs, and industrial chassis rather than as a standalone unit.

What applications is the ECM-WCL best suited for?

With triple display output, dual 2.5GbE, four serial ports, GPIO, and WWAN/Wi-Fi expansion, the ECM-WCL is well suited for industrial HMI, kiosks, digital signage, machine control panels, and gateway or edge computing applications.

How does the ECM-WCL compare with the ECM-PTL?

Both are 3.5-inch SBCs from Avalue's ECM series. The ECM-PTL uses the newer Intel Core Ultra Series 3 with AI acceleration, dual DDR5 SO-DIMM support up to 7200MHz/32GB, and quad display including 8K DP 2.1/HDMI 2.1b with PCIe Gen5 NVMe. The ECM-WCL uses a soldered Intel Core Series 3, single DDR5 6400MHz SO-DIMM up to 48GB, triple display, and PCIe Gen4 NVMe.

Should I choose the ECM-WCL or the ECM-PTL?

Choose the ECM-PTL for higher graphics performance, AI acceleration, and quad 8K display needs. Choose the ECM-WCL where higher memory capacity (up to 48GB), a soldered processor for vibration resistance, and triple display are sufficient for the application. TSL Automation Solutions can help match the right board to your requirement.

Is the Avalue ECM-WCL available from TSL Automation Solutions in India?

Yes, TSL Automation Solutions is an authorised Avalue distributor and supplies the ECM-WCL across India, handling sourcing, pricing, and technical support for OEMs and system integrators.

Does TSL Automation Solutions provide support and warranty for the ECM-WCL?
