I2C, Backup supply voltage accessible?

Q&A forumI2C, Backup supply voltage accessible?
erwin74 asked 2 years ago

I have two questions to the modules pin connectivity:

  • is backup supply voltage (pin 36) accessible
  • is the I2C bus (pin 44/45) accessible over the pixhawk connector

If not, then it would be nice to make these pins accessible in the next board version. 
Thanks in advance!

I’m second to that. I2c/SPI are handy when your micros only have 1 UART.

Hi erwin74, Vincent,

Backup supply voltage is connected to VCC, thus is not available for you to use it.
I2C bus is also not available in the board.
