Product description
Pico-2CH-RS485 provides serial communication via RS485 for Raspberry Pi Pico. The module uses two independent RS485 channels and converts UART signals to RS485. It is suitable for industrial applications, data acquisition, and long-distance communication.
The design is adapted for direct mounting on Raspberry Pi Pico via pin headers. The two channels can be used in parallel, providing flexibility when communicating with multiple devices such as sensors, PLCs, or other RS485 nodes.
The module is equipped with SP3485 transceivers. Integrated protection in the form of transient voltage suppression (TVS diodes) improves robustness in electrically noisy environments. TX/RX indicator LEDs for each channel make it easy to monitor data traffic.
With support for both C/C++ and MicroPython, along with available example code, the module can be quickly integrated into new or existing projects.
