Powered
Front
Back
The Minibadge includes a spiffy DC801 design and two automatic slow-cycling RGB LEDs
The Minibadge can be used in two ways:
- SAINTCON Minibadge Mode
- Shirt Pin Mode
- Insert the LEDs into the back of the board with the shorter legs toward the top
- Bend the legs of the LEDs over to contact the pads
- Trim legs to pads and solder
- Pick a resistor and solder R1: 0 - Brightest, 20-55mA 470 - Bright, 3-4mA 1k - Not so bright, 1.5-2mA
- Break the pin headers to fit
- Cut the sockets into two 8 pin sockets
- Insert the sockets with pins into your SAINTCON badge
- Place the DC801 Minibadge onto the pins and solder
- Flip your SAINTCON badge over and solder on the sockets
- Follow above, but don’t use the pin headers
- Solder included button pin to large pad at top
