Thanks for your info.
When you saying "(not sure if you need the hub, I think it depends on the receiver you are wanting to use)." you mean that if i place a voltage sencor straight from battery to reciever's telemetry port without using the sencor hub will do the job? i'm affraid this will burn the reciever instantly, specialy if the battery is more than 7.4 volts.
To let you understand what i want to clear please take a look in this page (
http://code.google.com/p/er9x/) scrolling down you can find the article "telemetry details" in pdf format.
And something else..
The connections to the main board to have a clear comunication between module and system requires among others a by passing of the 2 (unused) resistors (left end on board under the procesor) to the uper 2 pins nr 7 & 8.
The same pins have to short sirquit in case i want to add an sd memory card breakout board to the system.
So is this producing some problem to the hall cirquit?
Thanks
See you
