RF1_12V Assembly Guide v1.3 and earlier
Before starting make sure you have all the parts available from the BOM. Note that there are as many as five ceramic capacitors -- two 22pF and three .1uF (one optional) -- and they may look exactly alike except for the markings; don't mix them up. Similarly, there are two voltage regulators that also may look alike and can be confused.Step 1:
Note: the capacitor near the RF 2x4 header is optional and not shown in the picture
- Note: The RF1_12v bom is not using polarized capacitors for either of these. If you are using your own capacitors the polarity has been indicated on the PCB.
- Solder the .33uF and .1uF capacitors for the 3.3v Regulator(.33uF is Yellow in this picture)
- Note: The 5V and 3.3V regulators on this board are not pin compatible (or interchangeable)
Step 10: (optional)
- In your bom depending on your choice at time of purchase this may be a male or female 2.54 pitch header, or none.
Step 11: (optional)
- Solder the single pin for the 12V out . This is used as a pin to connect to expansion boards such as the RGB Controller.
Step 12: (optional)
- Instead of using a 4 pin header you should probably use one of these 4Pin Waterproof connectors!
- Solder the 2 10uF capacitors for the 5v Regulator (MCP1702)
- Solder the DC Jack. Note, the board utilizes a center positive DC plug. You may choose to substitute this for a common 2 wire terminal which will fit in the DC Plug footprint. Or Solder wires directly to the board.
- Power Verification prior to installing the Atmega and the nRF24L01.
- plug a dc source of 12V power in the DC jack.
- Verify that the Atmega (pin 7) is 5v=
- Verify that the Radio header (pin 2) is 3.3v
Step 16: If all checked out ok in step 15, Install the Atmega and nRF24L01 Transceiver.
Step 17: Load some code and blink!....
