A different way to tell the difference between Hardware A and Hardware B 18Ms

Currently the only way to confirm the hardware type is to check the back of the module, but if your modules are all in armored cases and you have a lot of them this turns into a Herculean effort.

Dev Completed. Will be available in firmware 7.2.x and a new release of 6.1.x. 18M modules will power on and indicate hardware type.

Firmware 6.1.6 and 7.2.0 and higher will now show HdA and Hdb on boot to identify an A or B hardware 18M.

I agree with this one. In fact I have a few mods that have the indication of both A and B according to the guide of what to look for.

Roger Meyer the end all tell is the wireless radio. This is 100% how to tell A vs B today. But firmware will do it before
