2.1 MIKROBUS™ INTERFACE BOARD PINOUT

Figure 2-2: mikroBUS™ Pinout

The mikroBUS™ pinout is shown above with the combination of two 1x8 female headers. In mikroBUS™ interface board, mikroBUS™ compatible host connectors are mainly provided to support Click Boards by MikroElektronika and they are categorized to UART, SPI, I2C and 1-wire interface where users connect the Click board accordingly depending on its communication interface. The unused interface is left no connection in each mikroBUS™ connector.

The 3 communication interfaces (UART, SPI, I2C) are connected to VK series development kit directly while for 1-wire bus, a 1-wire-to-I2C converter is inserted to support it through I2C.
