2.4 GHz Transmitter and Receiver for Model Aeroplanes

ZigBee technology for model construction

2.4 GHz Transmitter and Receiver for Model Aeroplanes
For a number of years now, remote radio control systems for models that operate in the 2.4 GHz band have been available. This technology is highly robust against interference and offers the option of telemetry which was not permitted with the older technology which, depending on the country, uses the low VHF 27 MHz, 35 MHz, 41 MHz or other allocated bands. The project described here offers the option of effortlessly expanding a lower VHF system with 2.4 GHz SHF technology. Because this is a fully open system, it can, to a large extent, be adapted to suit your own needs.

D2 & D3 -> new type, old : ES3A, new : GF1A

R15 -> new value, old : 47K, new : 3K3

The value of resistor R3* should be 6K8 when the type of the LCD is POWERTIP PC2004ARS-AWA-A-Q as mentioned in the list.

The software as been updated to V1.01 (serious bug removed)
