X8R2Analog: Analog voltage detector for FrSky X8R telemetry
This device can be used to report voltages via telemetry with the X8R receiver and the FrSky Taranis transmitter. It utilizes a small 8 pin microprocessor to sense a voltage via an analog to digital converter and a voltage divider circuit. This board has its own 3v3 power supply and is fully self contained. There is a blue power indicating LED that will light when connected to the s.port interface on the X8R receiver.
0.0 - 18.2v (will support higher voltage, but will only report the ranges listed e.g. will report 18.2v until battery voltage drops below 18.2) NOTE: DO NOT exceed 25v or you will damage the microprocessor.
Hi-Resolution jumper: Selects the resolution that the X8R2Analog uses to report voltage.
Jumper installed: Improves accuracy (useful for 3S and smaller batteries)
Jumper not installed: Normal accuracy
Note: Make sure you enter the correct MAX voltage in the Taranis telemetry setup so the scaling of the values are correct.
Use a standard servo extension cable to connect to the s.port connection on the X8R (not the s.bus connection). This device must be the only or last device in the s.port chain as it does not support pass through. Please verify the pinout prior to connection with specific interest on matching the positive and negative wires. Serial to S)ignal, positive to +, negative to -
