baofeng releases the upgrade version of uv5rm lately , adds gps module and aprs function.
it should be useful for those who wanna discover this stuff.

That is one strange MCU there, I get no hits on it, who knows what is under the hood. Maybe some custom Cortex-M0? You could probably attach a debugger (PicoProbe, DAPLink or maybe even STLINKv2) to the connector on the bottom (SWCLK, SWDIO, GND, 3V3) but the flash will be probably locked. Otherwise it uses FD6818 which was not used in open firmware radios yet.

Empty area is probably for Bluetooth module which was not installed. The RF part contains 11W MOSFETS, GPS module is from Wintec Semi. The rest of the labels I was not able to read

baofeng releases next version call ar26/ur26, it now contains gps and bluetooth module, 5rh pro becomes a vintage stuff after selling for a month, probably no one wanna pay attention to this toy anymore
