Step 24: ELV-04 Board

Next in line is the power board: the ELV-04.

This is a pretty heavy duty power supply board - which is a must, given the multitude of all the motors that it runs.
Here are the pin outs:

  J17 - power from the transformer and a detect line for battery power
    red- 9v in
    black- ground
    brown- battery +V

    BAT1- battery connector
     pin1- ground
     pin2- 9v from battery

  J10- powers audio board
    red wire 1.5v
    black wire- ground

  J14- powers main cpu
     red- 6v out
     orange-VR power -8V will not be using this line
     black- ground
     black- ground
     brown- battery detect +9V if batteries are not in and power plug in

  J49- powers ELV-08 board +9V
  J75- powers ELV-09 VR board +9V we will use this for our own VR board
  J15- powers ELV-06 board +9V
  SW1 On/Off switch

So far, we have seen the boards that control all facial movements and its power supply board. The ELV-01, which is the main CPU, is not needed either; all programming will be done with Basic stamps and a custom control board, which we will visit later.
