Avalue EPX-APLP Intel Apollo Lake 2.5" Pico-ITX SBCs with Dual 2.5GbE and Triple Display

Signage players, kiosk controllers and compact HMIs are often built into housings with space for little more than the display and a small board. The Avalue EPX-APLP series fits that brief: 2.5″ Pico-ITX SBCs measuring 100 x 72 mm, built on Intel Celeron processors from the Apollo Lake family. Both boards drive three displays, carry two 2.5GbE ports and run from a single 12 V DC supply, which keeps the power design inside the enclosure simple.

Apollo Lake is a mature, low-power Intel architecture, and on the EPX-APLP it is paired with one 204-pin DDR3L 1600 MHz SO-DIMM slot for up to 8 GB. Integrated Intel graphics feed a DP++ output at up to 4096 x 2160 at 60 Hz, HDMI at up to 3840 x 2160 at 30 Hz and an internal dual-channel 18/24-bit LVDS connector for panels up to 1920 x 1080. A hardware watchdog, Realtek ALC888S audio with an onboard 2 W stereo amplifier and an AMI BIOS with AT or ATX power modes complete the board.

Two processors set the range. The EPX-APLP-3350-B1R uses the dual-core Celeron N3350 at up to 2.4 GHz within a 6 W TDP, the lower-heat choice for single-screen signage and simple control software. The EPX-APLP-3455-B1R moves to the quad-core Celeron J3455 at up to 2.3 GHz and 10 W, giving more headroom for multi-display content, browser-based HMIs or several services running together. I/O, memory and temperature rating are identical, so the decision is compute against power budget.

Rear I/O on both boards includes two RJ45 ports on Intel I226LM 2.5GbE controllers, two USB 3.0 Type-A ports, DP++ and HDMI, with a lockable 12 V DC jack. Internal headers add four USB 2.0 ports, one RS-232 port and 8-bit GPIO. An M.2 B-key socket in 2242, 2260 or 3042 size carries PCIe x1, USB 3.0 and SATA signals with a SIM slot, so it takes either an SSD or a cellular modem, and an M.2 E-key 2230 socket takes a Wi-Fi module. One SATA III port with its own power connector adds a 2.5″ drive.

The EPX-APLP series operates from 0 to 60 °C in 10 to 95% non-condensing humidity and weighs 0.3 kg. That suits indoor cabinets, retail fixtures, building controls and light industrial machines, where a small board, a single DC rail and three display outputs matter more than an extended temperature rating.
