This is a placeholder topic for “MCP3424 18-Bit ADC-4 Channel with Programmable Gain Amplifier” comments.
The module integrates MCP3432 A/D converter chip. The module can provide analog input function for Raspberry Pi and provide high accuracy analog input for Arduino.
How can I connect this module with an ESP32 to have extra 4 channels of 18 bit?
The MCP3424 is an I2C device, and the ESP32 has an I2C bus. Refer to the documentation for the sensor for specific programming requirements.
