Jumpers/Wiring
Regarding Jumpers, Pi Hat VMC has no jumper configurations needed, in contrary to other members of the Pi Hat family. The only jumper present is the bootloader jumper.
The Pinout of the Pi Hat VMC is presented below.
On table below, Driver High outputs the voltage supplied to the Pi Hat by Pin 3 of the image above. In turn Driver Low outputs the GND of this power supply, connected through Pin 2 of the image above.
| ID | Function | Comments |
|---|---|---|
| a | Power to Driver High | This pin outputs the same voltage level (supplied by pin 3) used by Driver High Pins when they are active. |
| b | Power | 5V @ 6A (Max) |
| c | GND to Driver Low | This pin outputs the same GND level (pin 2 GND) used by Driver Low Pins when they are active. |
| d | UART2 TX and RX | Not used. |
| e | Digital Inputs | Must be pulled to GND (pin c) |
| f | Power to Driver High | This pin outputs the same voltage level (supplied by pin 3) used by Driver High Pins when they are active. |
| g | Driver High Out | When activated, these pins output the same voltage supplied to pin 3 or the MDB voltage if the device is powered by MDB. |
| h | Driver Low Out | When activated, these pin are pulled to GND level (same as pin 2). |
| i | GND to Driver Low | This pin outputs the same GND level used by Driver Low Pins when they are active. |
| 1 | MDB VMC | VMC MDB Connector, used both for controlling MDB Peripherals and Powering the device if MDB power is supplied somewhere else. |
| 2 | Power Supply GND | |
| 3 | Power Supply VCC | 24V @1A , this voltage will be used by the Output Pins and also to supply Power to the MDB line. If there is an external MDB Power supply being used, this pin can be left open. |
