JP1: usb cable: 4 wires from the A type USB connector: 1) RED; 2)
WHITE; 3) GREEN; 4) BLACK
JP2: RC transmitter cable: 2 wires from buddy box: 1) PPM SIGNAL; 2) GND
JP3: ICSP connector: SIL 5 pin male connector: 1) VPP; 2) VDD; 3) VSS;
4) RB7; 5) RB6
RES1: 4 MHz ceramic resonator (3 terminals with built in parallel
capacitors) for example muRata CSTCC4.00MG
C1: 200n
capacitor (0805)
C2: 100n capacitor (0805)
R1: 22k resistor (0805)
R2, R4: 10k resistors (0805)
R5: 200 Ohm resistor, but only if D1 is blue !! (0805)
IC1: PIC18F2455-I/SO or PIC18F2550-I/SO microcontroller (28-Lead SOIC)
D1: blue led; if you use other color put R5=1k !! (0805)
T1: BC846 transistor (SOT23)
R3: 1.5k resistor
(0805): NOT NEEDED (see notes below)
Notes:
1) The pull-up of D- line is done internally and is software
configurable so you don't need to use R3. Solder it
only if you modify the firmware sources disabling internal pull-up.
