Raspberry Pi 3 Model A+ 512MB RAM

This module is used to extend the Raspberry's 40 GPIO pins to another set of 2x20 male pins and 8 parallel pins accessible on the terminal blocks in the that test leads are pushed. The electronic board offers great reliability with the Raspberry and is very easy to connect thanks to its existing suitable accessories but not included.
The module offers a set of mini jumpers to configure the GPIO.

For Raspberry Pi 2 and Pi 3, B and B +.

QWIIC is a connection standard developed by Sparkfun enabling a quick an easy connection of peripherals without a need to solder pins, without any mismatches due to polarized connector. And on top of that you can "daisy chain" them! 

This hat pretty much opens the whole QWIIC universe in front of your Pi. It features 4 QWIIC ports all on the same I2C bus (GND, 3.3V, SDA, and SCL).

A universal  2x20 GPIO makes it compatible with all Raspberry Pi boards, as well as Google Coral and Jetson Nano.

Note:  For a secure connection in some applications, you'll need to add a pair of 1x20 stackable headers to extend the pins to your cart.
