This is home made breakout boards for RFM22 or RFM23BP HF modules.
One proto board is set as transmitter , the other one is receiver :
The Transmitter sends a frame every 3 seconds : blue and red LEDs flash during transmission.
When the RX board receives the frame its blue led flashes 3 times.
(Green led informs that receiver is in RX mode)
Code has been written in C and compiled with XC8 Microchip.
PIC 18F2620 @ 8 MHz ( internal oscillator, no crystal onboard )
PIC & RFM22b modules are 3.3v powered.
PIC does not use interrupts.
Because these boards are home made and designed by me you won't find them in any store.
However i can sell some PCB to you ( without components soldered on it ) + proto board schematic for 6€ / pcs.
Fell free to contact me.
