Many of our Raspberry Pi expansion boards are supplied with the connectors unsoldered. We have chosen to sell the boards this way because it makes it easier for the user to modify the board by adding their own connectors or fitting it in a lower profile case. To make the soldering of...
Our Raspberry Pi Expansion boards use either the I2C pins, UART or SPI pins on the Raspberry Pi 's GPIO header.
All of the other GPIO pins are available to use via the stacking header connector.
I2C Pin Usage
The following expansion boards use the I2C GPIO pins:
