3.3 Staggered Connector
The staggered connector consists of a pair of 1×8 header footprints, J100 and J101. The staggered design, in which each hole is shifted 8 mils (~0.2 mm) off-center, allows standard 100 mil pin headers to be used without soldering to the board. Once firmly in place, the pin headers can be used in applications such as pin sockets and prototyping boards without issues.
This connector includes all UART, I2C, SPI, and all IO pins.
