Instructions
- Solder the 3 .1uf Capacitors
- Solder the USB connector, note the 5 pads under the connector, you should apply a lot of flux to those pads and pins prior to soldering.
- Solder the FTDI Chip as shown, Use flux on the pads and Solder wick to clean up any excess solder.
- Solder the two 1k Resistors used for the LEDs (Optional if not using LEDs)
- Solder the LEDs as indicated, note the picture showing which orientation
- Solder the 10uF capacitor and the Reset Button.
- Solder the power jumper, and add the jumper to the power setting as desired, 3.3v Shown.
- Solder the 5 Pin Serial header, You can solder this as through hole OR flat as show in the picture below.
- Optionally Solder the 6 Pin Serial Header.
Fix issue with v0.2 PCB
the 0.2 pcb has an issue where it needs a mod wire added between the DTR pin on the 6 pin header to the capacitor next to the DTR pin on the 5 pin header. This DTR pin and Capacitor is what makes the Auto Reset function work when updating firmware on RF1 and other similar devices.
Add a piece of Mod wire (single strand of Cat 5 works great) between the two pins as shown here. You can add it on the top or bottom of the board.
