AJMRTC 2Channel UART To RS485 module is professional serial expansion board for Raspberry Pi Pico and Picoseries singleboard hosts. Adopting SP3485 transceiver chip, this module converts two groups of TTL UART signals into standard RS485 differential signals, realizing longdistance antiinterference serial communication with industrial sensors, PLC controllers and legacy automation equipment. It uses standard Pi Pico header, perfectly aligning with Pico series pin positions for convenient installation without complex wiring modification. Dual independent channels work separately without signal conflict, meeting multidevice access requirements in embedded development scenarios. Smallsize PCB fits inside limited project enclosure space. Please doublecheck signal pin definition before poweron. Basic embedded development knowledge is recommended for assembly. Raspberry Pi Pico main board is not included in this package.
