ASRock Industrial IMB-1234V Mini-ITX Motherboard with Intel Core i3-1215UE, Quad Display and 12 to 28 V DC

Signage players, HMIs and gateways often need several screens and serial ports more than raw processing, on a compact board fed from DC. The IMB-1234V is the Core i3 build in the ASRock Industrial IMB-1234 series: a Mini-ITX motherboard with an onboard 12th Gen Intel Core i3-1215UE, fed from 12 to 28 V DC.

The Intel Core i3-1215UE is a 12th Gen Alder Lake-P processor with two Performance and four Efficient cores, the entry option in the series. Two DDR4-3200 SO-DIMM sockets run in dual channel for up to 64 GB. Intel Iris Xe Graphics drives two HDMI 2.0b outputs and two DisplayPort 1.4a outputs over USB-C, all at up to 4096 x 2160 at 60 Hz, plus internal dual-channel LVDS and eDP 1.4b connectors, with up to four displays at once.

Two Intel I225LM controllers give two 2.5GbE ports. The rear panel carries two USB 3.2 Gen 2 Type-A, two USB 3.2 Gen 2 Type-C with DisplayPort output and two USB 2.0 ports, and internal headers add one USB 3.2 Gen 1, two USB 2.0, six COM ports (two RS-232/422/485 and four RS-232) and 4-in/4-out GPIO. Storage is an M.2 M key on PCIe Gen4 x4 and two SATA 6Gb/s ports with Intel VMD RAID 0/1. An M.2 B key with SIM takes a 4G or 5G module and an M.2 E key takes Wi-Fi. The IMB-1234M adds a Core i5 with vPro and AMT, and the IMB-1234P is the Core i7 build.

Power is 12 to 28 V DC on a lockable DC jack, with AT and ATX modes. The board operates from -20 to 70 °C and stores from -40 to 85 °C at 5 to 90% humidity, and carries a TPM 2.0 chip, a 256-segment watchdog timer and Realtek ALC897 audio. It measures 170 x 170 mm on the Mini-ITX footprint.
