Avalue EMX-TWLP-N250-A1R Intel N250 (Twin Lake) Thin ITX Motherboard with 12 to 24 V DC Input and Dual 2.5GbE

Ticketing machines, vending kiosks and self-service terminals tend to carry more serial devices than screens: a card reader, a receipt printer, a coin or note validator and a barcode scanner, all talking to one board. The EMX-TWLP-N250-A1R is the Intel Processor N250 build in the Avalue EMX-TWLP series of Thin ITX motherboards, with six COM ports and a 6 W fanless processor for exactly that kind of terminal.

The N250 is a quad-core Intel Twin Lake processor with a 6 W TDP, cooled by a passive heatsink. One DDR5 4800 MHz SO-DIMM slot takes up to 16 GB, enough for a kiosk application, a local database and a browser front end. Integrated Intel Graphics drives HDMI 2.0b, DisplayPort 1.4a, DP++ and an internal eDP or dual-channel LVDS connector, with up to three independent displays and 4K output on HDMI and DisplayPort.

Six COM headers, two RS-232/422/485 and four RS-232, and 16-bit DIO cover the serial and switched peripherals. Two 2.5GbE ports on RJ45 separate the back-office network from local devices. Four rear USB 3.2 Type-A ports, an internal vertical USB 3.2 port and four USB 2.0 headers add touch and scanner connections. An M.2 B-key with a SIM slot takes a 4G module for sites without wired backhaul, an M.2 E-key takes Wi-Fi, an M.2 M-key takes an NVMe or SATA SSD, and a SATA port and PCIe x1 Gen 3 slot add a drive and a card.

The EMX-TWLP-N250-A1R runs from 12 to 24 V DC on a lockable barrel jack or a 4-pin connector and operates from 0 to 60 °C with 0.5 m/s airflow, with TPM 2.0 and CE, FCC and RoHS compliance. The EMX-TWLP-N150-A1R is the matching quad-core 6 W build on the N150, and the EMX-TWLP-N355-A1R moves to eight cores at 15 W for heavier workloads.
