3.4 mikroBUS Socket (J402)
A mikroBUS socket (J402) expands the functionality of the WFI32-IoT 2.0 board using the MikroElectronika mikroBUS Click adapter boards.
The mikroBUS connector consists of the following:
- Serial Peripheral Interface (SPI)
- Inter-Integrated Circuit (I2C)
- Universal Asynchronous Receiver-Transmitter (UART)
- Reset (GPIO)
- Pulse Width Modulation (PWM)
- Analog and interrupt lines
- 3.3V and 5V power lines
