BreadBoard Mates MB Adapter provides development boards with MikroBUS sockets with a MateBUS interface to connect products directly. This adapter features a 5-pin programming header to program the connected device through the MB adapter using the BBM programmer. A selection switch is located on the back that allows this adapter to switch between the device programming mode or connection of the device to the host. BreadBoard Mates MB Adapter connects to the MikroBUS interface and utilizes the Serial UART of the Host to connect the MateBUS headers.
