@Joerg:
Thanks. Most is clear. A few clarifications:
-The note "JP1 CLOSED, VCOM max +4.5v!". Do I need to close JP1 or not, to waranty +4.5v in +VB?
- the BLDC board is powered by who?: by the +5V in one of the ESC´s or by the pins marked as "power"?. If "power" is used (I guess batery connected to it) do I need the +5V?
- For voltage sensing I´ll close JP2 and configure PA6 as ADC12_IN6. Where in the code?
Thanks for your help
