HAMKit VMAC PiHat v1 Overview

The HAMKit VMAC AV PiHat v1, is a small board that provides a very flexible Audio and Video Switching Matrix, with on-board DTMF Decoder, EEPROM and DC Regulator.

A new version of the HAMKit VMAC AV PiHat v2 can be found here.

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.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Typical applications for the HAMKit VMAC PiHat are:

• ATV and DATV Repeater Control Logic
• ATV home, mobile or portable stations
• FM Repeater Control Logic
• Audio / Video matrix controller
  • • ATV/DATV
    • CCTV (Matrix or Auto Cycle Select)
    • FPV (5GHz Video Camera Receivers)
    • Video remote switching
  • Audio remote switching

The HAMKit VMAC PiHat is easily software controlled from the Raspberry Pi using your preferred coding language such as Python and all software provided is Open Source in order to encourage people to develop and help each other with ideas and applications.

Part Built Kit:

• 1 x HAMKit VMAC PiHat PCB (SMT Populated)
• 10 x RCA PCB mount sockets
• 1 x 3.5mm 4 pole socket
• 1 x DC10 2.1mm socket 5A
• 2 x JST 6 pin cables
• 2 x 20w headers (these will require slight filing in the middle ends)
