Metropolis firmware update instructions

In the Metropolis instruction manual, there is indication to do firmware updates, including link to where firmware can be downloaded, but I don’t see any instructions how to do the update.

I do not see a micro USB accessible from the back of the module, which would give some indication how to proceed.

Can you provide instructions to do a firmware update?

The Metropolis firmware update requires the USP ISP which can be acquired here:

Instructions can be found within the Intellijel firmware updater application.
