Due to a small bug in the Receiver PCB and some small signal problems in the Transmitter PCB, I decided to do some small changes.
Remote RX PCB:
The RX PCB had a small problem due to the voltage divider being connected to the voltage regulator instead of the battery.
Other small updates:
- Extra Input/Output connector
- Coupling and Decoupling capacitors
- Possibility to add a resistor for the piezo buzzer, if needed
Remote TX PCB:
Because of the noise, I had to add coupling and decoupling capacitors for each IC as well as for the voltage regulators.
A bigger change is the fact that for the joysticks there’s a redundancy channel allocated for each axis. This was possible because the IC had 8 channels, while for the joysticks it was needed only 4.
On the back of the PCB there’s also a new connector that could be used to INPUT or to OUTPUT data.
