I am trying to find an external compass for Navio+. I read in the forum that those based on HMC5883L chip (with 5V input voltage) should work. However, in docs it says for Navio that “UART, SPI, I2C signal pins – 3.3V (CAUTION! connecting 5V logic device to these pins may damage your Raspberry Pi!)”. Is it the same for Navio+? Or are there boards with 5V input voltage but 3.3V signal pins? If so, does someone have a link to one? (I cannot find them)
i believe hmc5983 should be the newer version ( i didn’t notice any changes but maybe in some circumstances it behaves better)
this one works fine and ships faster
or slower
they both worked fine!
