I2C master modules for communication with the I2C bus

I2C master modules

An I2C master is a central control device that coordinates communication on the I2C bus. It initiates and terminates data transmission, sends addresses to the slave devices and controls the clock for synchronization.

I2C masters can read sensors and forward the values ​​to other systems, e.g. via Modbus-TCP or MQTT, or take over control tasks independently.
