kombee Assembly Instructions v03
These instructions are for the kombee v0.3 PCB
|C6||10uF FK16X7R1C106K capacitors|
|R1||10k 0805 resistor|
|U1||28-pin DIP socket|
|Q1||16Mhz Ceramic resonator|
|TTLSerial||2.54mm 5-Pin header - Optional|
|XB1||2.0mm 10-pin header|
|Reset||2.54mm 2-pin header|
|RF||2x4 2.54mm pitch female pin header|
Solder the 10k pull-up resistor (resistors have no polarity; either way will do).
Solder the two .1uF/100nF capacitors C3,C5, C6(*this is now a 10uF FK16X7R1C106K ) . There is no polarity for these either.
Solder the ceramic resonator; it also doesn't have polarity.
Add the XBee pins; these are set on a narrower pitch and care needs to be taken soldering so that you don't bridge (short) the pins.
If you will be using an XBee Explorer board to program your kombee board you do not need to install the serial header shown here; if using a regular FTDI adapter you will need to add this header. NOTE: you cannot apply 5v power to this header while the RF transceiver is in place.
Install the two-pin Auto Reset header.
Add the 28-pin socket.
Add the 2x4 female pin header.
Add your Atmega328P-PU.
Connect your kombee and check to make sure that your source power is set to 3.3v
Now to test your board is working properly you need to connect it to power, connect the kombee to your serial programmer (also see note in Step 6 regarding the auto reset enabled jumper). Measure the voltage at pins 1&2 of the nRF header. If the reading on Pin 2 is between 3.3v and 3.6v, you did it!
