B.1.5 GS2200M SKB Arduino Connector Pinouts
The SKB may be configured as host or a shield. Each field shows the label with the GS2K
signal listed in parenthesis. The UART port can be configured to route to UART0 or
UART1 of the GS2000 via header J18. +5V can optionally be supplied from the 5.0V
regulator to power to shields. VIN can also be optionally supplied with 5V directly from
the USB port. The SPI port can be configured for master or slave mode via header J20. In
shield mode, +5V can be used as the power source by setting jumper J19 appropriately.
Table 17, page 46 , Table 18, page 46 , Table 19, page 47 , Table 20, page 47 gives the pin
assignments.
