2.4 mikroBUS Socket
One mikroBUS socket, J503-J504, is available on the development board. This socket can be used to expand the functionality using the MikroElectronika Click board™. The mikroBUS connector consists of two 1x8 female headers with SPI, I2C, UART, RST, PWM, analog, and interrupt lines as well as 3.3V, 5V, and GND power lines.
