+5V (Device Supply Voltage)
Display supply voltage pin. This pin supplies the MatesBUS with 5VDC from the Host board.
GND (Module Ground)
Device ground pin.
TX (Serial UART Transmit – MatesBUS)
TX of the MatesBUS connects to RX of the Host board, this is the 3.3V Asynchronous Serial UART Transmit for communications between the device connected to the MatesBUS headers and the Host.
RX (Serial UART Receive – MatesBUS)
RX of the MatesBUS connects to TX of the Host board, this is the 3.3V Asynchronous Serial UART Receive for communications between the device connected to the MatesBUS headers and the Host. This pin is 5V tolerant so is compatible with 5V UARTs.
RESET (MatesBUS Reset)
This pin is primarily connected to the Mates Ptogrammer header, for programming the connected MatesBUS device, such as the TIMI-96. Is it also connected to the Host via a 680 ohm resistor to the RST pin on the MikroBUS, making it possible for the Host to initiate a reset of the MatesBUS device as required.
NC (Not connected)
These pins are not connected or used on the MatesBUS by the Host.
