Thin PCB shim that plugs directly onto the Raspberry Pi GPIO header and exposes a JST SH 4-pin (Qwiic / STEMMA QT) I2C connector. No soldering required; thin enough to stack with HATs or bonnets.

Adafruit product page states the SHIM JST SH connector connects to the Raspberry Pi I2C SDA line.
Adafruit product page states the SHIM JST SH connector connects to the Raspberry Pi I2C SCL line.
Adafruit product page states the SHIM connects to 5V from the Raspberry Pi GPIO header.
Adafruit product page states the SHIM connects to Raspberry Pi ground.
Product page states the SHIM has a 3.3V regulator so it works with Qwiic or STEMMA QT devices.
Single JST SH connector exposing the Raspberry Pi I2C bus for Qwiic/STEMMA QT devices.
