The GMOD-QWIIC-2IN1 is a compact passive I²C breakout module that bridges dual Qwiic JST-SH connectors to a standard 2.54mm pin header, exposing SDA, SCL, VCC, and GND signals. Operating at 3.3V only, it enables clean, solder-free integration of Qwiic-compatible sensors and peripherals with microcontrollers such as GLYPH, Arduino, ESP32, STM32, and Raspberry Pi — ideal for rapid prototyping, daisy-chaining I²C devices, and embedded IoT wiring.
