AS noticed before, ioShield-L consists of WIZ550io and an interface board to MSP430 LaunchPad. Therefore to connect ioShield-L with LaunchPad is required. All pins to be connected between ioShield-L and LaunchPad are VCC, GND, nRESET and four SPI related pins.
|Pin No.||I/O||Pin Name||Description|
|J1.1||P||VCC||Power: 3.3V Power Supply|
|J1.7||O||P1.5||SPI Chip Select|
|J2.14||I||P1.6||SPI Master In Slave Out|
|J2.15||O||P1.7||SPI Master Out Slave In|
ioShield-L is designed to plug in to the corresponding pins of MSP430 LaunchPad, and normally users don't need to care its pin map.
