EPC-TWL

Series: EPC

Manufactured byAvalue

The Avalue EPC-TWL is a compact fanless box computer built on Intel Twin Lake processors (N150 default, N250 or Core 3 N355 optional), pairing modern low-power efficiency with onboard TPM 2.0 security. Based on the ECM-TWL SBC, it accepts DDR5 4800MHz memory up to 16GB and offers an M.2 Key-B 2242 SSD plus an internal 2.5" drive bay for flexible, high-capacity storage in a rugged 177 x 127 x 57 mm chassis. The EPC-TWL provides dependable industrial connectivity: dual 2.5GbE RJ-45 (Intel I226-V), two RS-232 COM ports, front and rear USB (USB 3.2 Gen2 and USB 2.0), DisplayPort 1.4a and HDMI 2.0b each up to 4096x2160 @ 60Hz, and dust-protected antenna mounts for wireless. A wide 12/24V input with ATX power management, 0–60°C operation, and vibration/shock/drop validation make it a robust edge node for Windows 11 or Linux.
