AJMRTC 2Channel UART To RS232 module is dedicated conversion expansion board for Raspberry Pi Pico, powered by SP3232EEN chip. This board transforms two groups of TTL UART signals from Raspberry Pi Pico into standard RS232 serial signals, enabling communication with legacy industrial devices, serial sensors and oldstyle control hardware. Dual independent channels allow simultaneous connection of two RS232 peripherals without hardware conflicts. Clearly marked pin headers simplify wiring work for firmware debugging, serial data acquisition and embedded prototype building. Compact PCB size fits well inside small project enclosures. Please doublecheck signal pin definitions before poweron. Basic embedded development knowledge is recommended for assembly. Raspberry Pi Pico main board is not included in product package.
