I have a project where space is essential. I have a Rc transmitter which sends info to a frsky receiver. In the robot i have a one motor with an esc and a potentiometer as feedback for position.
So this means i need:
1 pin for rc signal in(ppm)
1 pin for rc signal out(ppm)
1 pin for potentiometer in(adc)
1 pin for telemetry out(tx)
In addition it would be nice with
GPS in (rx)
Airspeed(ADC)
Altitude(ADC or spi/i2c)
Can i use it with some clever programing and resoldering?
