Navio2 sensors schematics

Navio / Edge Hardware

Hello,

I’m trying to reduce the latency of PX4 sensor acquisition and it seems that the culprit is the GPS driver which keeps the SPI bus busy.
Unfortunately, Navio2 has the sensors on the same SPI bus, which means that sensor data acquisition is serialized.

I would like to know if Navio2 sensors have their INT GPIOs connected to RPI, so I could make the data read logic interrupt driven.

Thanks,
Nicolae

I’m mostly interested whether EXTPIN is connected [0] [1]

Hello there!

Here’s the pinout diagram. Unfortunately, as you may see, the INT pin is not present.
