DFI ADP253-BCI-80CR05E Intel Celeron 7305E 4″ Embedded Board with 9 to 36 V DC Input and Triple LAN

Serial-to-Ethernet gateways and data loggers are often bought in quantity, and the cost of each board matters more than its clock speed. What they need is plenty of COM ports, dependable networking and a DC input. The ADP253-BCI-80CR05E is the Celeron standard-temperature build in the DFI ADP253 series of 4″ embedded boards, built around exactly that I/O.

Its Intel Celeron 7305E (Alder Lake) runs five cores at 1.0 GHz within 15 W, which suits Modbus polling, protocol conversion and logging to a local database. Memory is 8 GB of DDR4 soldered on the board plus one DDR4-3200 SO-DIMM slot taking up to 32 GB. Intel UHD graphics drive HDMI, VGA and two USB-C ports with DisplayPort Alt Mode, so a maintenance screen can be connected when needed, though most gateway builds run headless.

Six COM ports (two RS-232/422/485 and four RS-232) take meters, drives and legacy controllers directly, without USB adapters, and 8-bit DIO shared with COM3 reads local contacts. One 2.5GbE port and two GbE ports on Intel I226 separate the field network, the plant network and an uplink. The M.2 B-key with SIM takes a 4G or 5G module for remote sites, the M.2 E-key takes Wi-Fi, and the M.2 M-key and SATA 3.0 port take storage. Two USB 3.2 Type-A ports and two USB 2.0 headers cover the rest.

The ADP253-BCI-80CR05E runs from 9 to 36 V DC on a locking barrel jack or 4-pin connector and operates fanless from -5 to 65 °C. It carries CE, FCC, UKCA and RoHS compliance, a discrete TPM 2.0 and a watchdog timer. For outdoor telemetry cabinets, ADP253-ETI-80CR05E is the same board rated from -30 to 80 °C, and ADP253-BCI-80I315UE adds six faster cores for a local HMI.
