2.6 ISP/SPI Header

The ISP/SPI Header is not mounted by default on the board. It is open for the user to mount manually. A standard 6-pin 2.54 mm pitch header is needed for mounting. The header can be used as a standard ISP/SPI extension for other modules/boards. The pin definition is shown in the table below.
