Purchased 2021-10-1 for Centipede
Control Board is newer version with 3 Pin connectors for Push Buttons.
Questions
How do I connect 2 pin happ buttons to 3 pin connector? Bottom pin on board looks like ground. Look on back all ground. But one of these must have electricity which one?
For Joystick we can still connect sanwa to 2 button connectors for Up Down Left Right. Shown in 4.
But sanwa has 3 pins. Why? Just Connect C and NO, Do not connect Sanwa NC pins.
While I can use 3 Button connectors for greens, how do I connect older style?
The smaller green system buttons come with special connectors and use old style pinouts.
New Version
Old Version had 2 Pins per button. For light up was PITA, but was easy for happ style.
The 5v red connectors could be used to power led lights only. See here for special wiring connectors to convert old style LED button to new 3 pin connector.
Polarity only matters for LED 5V power. Button of 3 pin connector is ground, which is used for both LED power and Button Press. Middle Pin is Yellow and used for button press. Top Pin is red for +5V Power. This means to connect Happ Style Buttons without LED just used bottom two pins on the 3 pin female connector on the USB Encoder Board.
The above Cables are for 3 pin Connectors on USB Encoder Board. Black is Ground. Red is Voltage. Blue or Yellow is switch signal for control.
