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 adapter boards. 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.
