+5V (Device Supply Voltage)
MatesBUS supply voltage pin. This pin supplies the MatesBUS with 5VDC from the 5V side header (H4)
GND (Module Ground)
Device ground pin. One GND pin is found on each H3 and H4 side headers.
TX (Serial UART Transmit – MatesBUS)
TX of the MatesBUS connects to RX of the Host board (or BBM Programmer), this is the 3.3V Asynchronous Serial UART Transmit for communications between the device connected to the MatesBUS headers and the Host. Connects to the TX on the side Header H4.
RX (Serial UART Receive – MatesBUS)
RX of the MatesBUS connects to TX of the Host board (or BBM Programmer), this is the 3.3V Asynchronous Serial UART Receive for communications between the device connected to the MatesBUS headers and the Host. Connects to the RX on the side Header H4.
RESET (MatesBUS Reset)
This pin is primarily connected to the BBM-Programmer, for programming the connected MatesBUS device, such as the TIMI-96. It can also be connected to a Host, making it possible for the Host to initiate a reset of the MatesBUS device as required. This pin is found on the side Header H4.
3V3 (3.3V Output)
This pin is the 3.3V output (where applicable) from the connected MatesBUS product (such as the TIMI-96), and offers 3.3V output for the User to power sensors etc. The availability and capability of this pin is purely dependant on what MatesBUS device is connected to the stand.
GPIO (GPIO Pins)
These GPIO pins are break-outs of the GPIO pins found on the connected MatesBUS product. The naming is left simply as GPIO, as the naming of the GPIO could change depending on what MatesBUS device is connected. Please refer to the MatesBUS product datasheet that is connected to determine the GPIO availability or capability. Not all GPIO pins may be used.
