micropython-modbus
A MicroPython library implementing Modbus RTU and TCP protocols for both master (client) and slave (server) roles.
What is micropython-modbus?
MicroPython Modbus is a library that implements the Modbus RTU and TCP protocols for MicroPython-powered devices. It allows these embedded systems to act as Modbus masters (clients) or slaves (servers), enabling communication with industrial sensors, PLCs, and other automation equipment. It solves the problem of integrating lightweight MicroPython devices into standard industrial networks.
Embedded developers and engineers using MicroPython on devices like ESP32, Raspberry Pi Pico, or other microcontrollers that need to communicate via the Modbus protocol in industrial or automation settings.
Developers choose this library because it provides a dedicated, full-featured Modbus implementation for the MicroPython ecosystem, supporting both RTU and TCP as well as master/slave roles. It is a community-maintained fork built upon proven work, offering reliability and comprehensive protocol support where few alternatives exist.
