EEPROM on Navio2 HAT

Navio / Edge Hardware
1

There is an EEPROM on Navio2 HAT which connects to pin 27 and 28 of Raspberry Pi 3 board. I read somewhere that this EEPROM is used for auto configuration or Navio 2 board specific ID.

I need more information on Navio2 EEPROM and need to know if PX4 code will work without the EEPROM?

Hi @dangtepau,

Sorry for the delayed response.

EEPROM on HAT has data about the vendor and its default specs. We never tested Navio2 working without EEPROM, so I can’t advise you something specific.

To which pin of Raspberry Pi 3, the PPM/SBus pin of Navio2 is connected?

Hi @pskoog3,

PPM signal goes to STM, placed on Navio2.

There is no direct connection of PPM to Raspberry Pi, only through STM.

6

From STM to which pin of raspberry Pi 3, for PPM signal?
