ADC connector (LiPo voltage detector input) on V2 boards (M4

-
- ONLY CLOSED JP1 JUMPER WHEN USED WITH BETA BOARDS! LEAVE OPEN WHEN USED WITH V2 PRODUCTION BOARDS!
-
- LiPo connected to V2 board (ADC terminal) for voltage detection - needed for fail safe.
-
- Mating connector on the other side
-
- Cable soldered to the PDB.
Yellow = LiPo + (goes to ADC terminal)
Black = LiPo - (goes to GND terminal)

If you bear with us a few days, we should have an option in the firmware to enable using the external voltage sensor/divider via a parameter. As of right now you'd still need some way to use ext. V as the main Vin (fw hack).

Hi Max,
SPI1 should be disabled since I don't know what PA6 is used for on the Cypress radio. In addition, voltage sensing only works on production boards when using external receivers. As soon as the Cypress is enabled (solder jumper on arm 2 on TOP closed) PA6 will be used for SPI! --> no more ADC readings! On V2 production boards the preference should be to use the ADC input.
Advanced users can get rid of the additional cable by using a custom board file (and knowing what they are doing).
Nevertheless, such a custom board file (with disabled SPI1 and PA6 enabled for ADC input) could be used for the BETA boards (M4r5).

Excellent, thanks. I'm going to use it with an r4 for now, but it would be cool if it worked with v2 as well. Yes, it's time to build something (with hardware)!
