Hi all,

I've found out that the magnetometer in the Revolution (the HMC5883L) is discontinued. Honeywell replaced that with the HMC5938, but that is now discontinued as well.

What does this mean for manufacturers of Revolution boards? Is there an alternate part that can work? If not, are Revo boards going to be phased out?

The project doesn't manufacture hardware, the only ones manufacturing revo boards are the Chinese.

The revo nano (no longer made) and a clone or workalike the Falcon F4 (farwestrotors.com) use a different sensor and are supported in the software now.  And of course the cc3d boards are supported.

Support for the Sparky2 board is being worked on.   It also uses a different sensor that's still made.  Several developers are flying (and like) them.  Official released support for it should  be available long before the Chinese run out of parts to make revos.

It is very unlikely that Chinese cloners would abandon Revo even if Mag would run out of supplies, they can easily change it to another compatible component or another brand. Design is open so anyone can just make own Revo, even adapted to own needs.

Probably the easiest thing to keep the Revo alive would be to replace the HMC5883L and MPU6000 with MPU9250 that is used on the Nano, FalconF4 and Sparky2.

Another observation, that might be a bit off, is that some devs see Sparky2 as the updated Revo...

Swapping the MPU9250 for the MPU600/HMC5883L doesn't keep the revo alive, it creates a new flight controller that requires new firmware and GCS support.  It wouldn't be any better than the Sparky2 so there wouldn't be any purpose to doing it.   It's a lot of work supporting a new board, the Sparky2 support has been being worked on for around 6 months and still isn't completely done.  The Chinese are already cloning the Sparky2 so the price should eventually drop down to around the same as the revo clones are now.

You're right, there are four developers that I can think of that are working with the Sparky2 and maybe others I don't know have it.  It's a popular candidate for a "revo replacement".
