VMAC PiHat v1 Specification
The HAMKit VMAC AV PiHat v1, is a small board which provides a very flexible Audio and Video Switching Matrix, with on-board DTMF Decoder, EEPROM and DC Regulator.
This board (available as a kit or built), was designed principally as a Raspberry Pi add-on board, however, it can also be connected to other I2C enabled devices such as Arduino, Microchip, Tablets or PC.
As the current consumption is very low, power is taken from the Raspberry Pi 3V3, via the GPIO header.
Various sample test code provided on our Wiki pages, using Python.
