Vszerda MCP2221A USB GPIO ADC I2C Module Board for Adafruit Stemma QT/Qwiic

SKU CH-ARZN-934FG

Converts USB to GPIO, ADC and I2C with a Stemma QT/Qwiic connector

  • USB-to-GPIO bridge with 4-channel ADC via MCP2221A
  • Stemma QT/Qwiic connector for solderless I²C expansion
  • Direct USB enumeration as HID, no driver install needed
  • Compact module adds analogue and digital I/O to any host

MCP2221A USB to GPIO I2C interface

This Vszerda module uses an MCP2221A chip to bridge USB with GPIO, ADC and I2C functions. It includes a Stemma QT/Qwiic connector for quick sensor attachment. The board suits makers and engineers adding USB control to custom circuits.

For prototyping and sensor integration

Developers needing a simple USB link for I2C sensors or ADC readings will find this board useful. It is not suited for buyers who require isolated USB interfaces or additional protected GPIO lines beyond what the MCP2221A provides.
