The first version of the receiver was based on an Arduino Diecimila and an XBee shield. It works on 2.4Ghz band,
and can control up to 6 servos. It receives data from the transmitter
for servo position, but can also transmit back information. As it is
home made, it requires a special transmitter to work with. It keeps
servo positions even if there is no transmitter.
is made with ready to use boards that you just need to fit
together. There is no need to make PCB and solder components, just some
soldering to adapt connections for the servos.
