X8R2Analog: Analog voltage detector for FrSky X8R telemetry
NOTE On the V2 versions, please always attach the ground lead on the analog side, the grounds are isolated on the X8R2Analog board and in some cases without the ground the unit will read a lower voltage than actual. ALSO, if using 3S or smaller, please install the hi-res jumper as noted below and set the A2 value on Taranis to 13.2v for scaling to be correct.
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
