RAK7391 WisGate Connect Connecting to WisBlock

Connectors Position

There are two WisBlock slots on the RAK7391 board, right next to the USB 2.0 and USB 3.0 ports. The WisBlock slots support various industrial protocols via WisBlock modules: IO, Analog, 0-5 V, 4-20 mA, ModBUS, and LinBUS.

Pin Definition

Both of the WisBlock slots connectors are with 40-pin high-density headers. Each of them is connected to a GPIO expander TPT29555-TS5R. The I2C addresses of these two GPIO expander chips are 0x26 and 0x27.
