PCB Header Assembly Jig
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 connectors or fitting it in a lower profile case. To make the soldering of the connectors easier, we have designed an easy-to-use paper assembly jig which you can download and print....
Raspberry Pi GPIO Pin Usage
Our Raspberry Pi Expansion boards use the I2C pins, UART or SPI pins on the Raspberry Pi's GPIO header....
