EPCM-2944 is the most feature-rich product in the EPCM2000 series data acquisition industrial control board. It not only has a complete underlying driver library and communication protocol, but also has a variety of peripheral circuits for data acquisition, large-capacity storage, communication and control, which can greatly reduce your secondary development time.
The EPCM‑2944 is the most feature‑rich board in ZLG's EPCM2000 series. It is built around an NXP LPC2378 32‑bit ARM processor and provides extensive I/O, storage and communication options, reducing the need for secondary development. The board supports 8 single‑ended (or 4 differential) analog inputs, 8 digital I/O (4 of which can be PWM), Ethernet, CAN‑bus, RS‑232/485, an I2C bus and a MiniISA expansion connector.
Technical details include a 5 V ±5 % power supply, ≤3 W power consumption, operating temperature from –40 °C to +85 °C, and a compact EPIC‑standard size of 188 mm × 125 mm. Storage options comprise on‑board flash (2 MB or 4 MB) and a CF card slot (up to 137 GB). The board runs µC/OS‑II with a FAT32 file system and built‑in TCP/IP and Modbus protocols.
