AJMRTC 2-channel RS485 expansion module is specially designed for Raspberry Pi Pico, Pico W and Pico 2. It adopts the SP3485 half-duplex RS485 transceiver chip and communicates via the UART bus, realizing reliable conversion between UART signal and RS485 differential signal. It supports up to 256 nodes on one RS485 bus, suitable for Modbus RTU, industrial sensors, smart control and long-distance serial data transmission. The onboard TVS protection circuit guards against static electricity and voltage surges. It uses pluggable terminal blocks for convenient field wiring, and standard pin headers for direct stacking on the Pico mainboard. It is widely used in industrial automation, smart home, data acquisition and DIY embedded projects. Raspberry Pi Pico mainboard is not included.
