Avalue EPX-TWLP Intel Twin Lake N150 and N250 Pico-ITX Motherboards with Dual 2.5GbE and Triple Display

A 6 W processor makes a difference in a sealed signage housing or a kiosk with no room for a fan, because there is less heat to move out of a small space. The Avalue EPX-TWLP series is built around that budget: 2.5″ Pico-ITX motherboards, 100 x 72 mm, on Intel Twin Lake processors that Avalue rates for fanless running with 0.5 m/s airflow across a 0 to 60 °C operating range.

Both EPX-TWLP boards use a quad-core Intel Processor N part from the Twin Lake family with a 6 W TDP, soldered to the underside of the board. One 262-pin DDR5 4800 MHz SO-DIMM slot takes up to 16 GB. Integrated Intel graphics drive DisplayPort 1.4a and HDMI 2.0b at up to 4096 x 2160 at 60 Hz, with an internal single-channel 18/24-bit LVDS connector for panels up to 1366 x 768. Firmware TPM, a hardware watchdog and an AMI BIOS with AT or ATX power modes are standard, with Windows 11 and Linux support.

The EPX-TWLP-N150-A1R carries the Intel N150, a good fit for single-screen signage, kiosks and small control applications. The EPX-TWLP-N250-A1R carries the higher-tier Intel N250 for builds that want more processing in the same 6 W envelope. Memory, I/O, cooling and temperature rating are the same on both, so the choice comes down to how much processing headroom the application needs over its life.

Rear I/O includes two RJ45 ports on Intel I226V 2.5GbE controllers, two USB 3.2 Gen 2 Type-A ports and stacked DisplayPort and HDMI connectors, with a lockable 12 V DC jack. Internal headers add four USB 2.0 ports, one RS-232 port, one RS-232/422/485 port and 4-bit GPIO. The M.2 B-key socket in 2242 or 3042 size carries PCIe x1, USB 3.2 Gen 1 or SATA with a SIM slot for an SSD or 4G modem, an M.2 E-key 2230 socket takes Wi-Fi, and one SATA III port adds a 2.5″ drive.

Every EPX-TWLP board carries CE, FCC, UKCA and RoHS compliance, weighs 0.3 kg and handles 10 to 95% non-condensing humidity. The series suits digital signage networks, self-service kiosks, building controls and light industrial machines that run indoors and need a small, cool-running board.
