Anyone using these microcontrollers?

[Bill Danielson]

I like the Feather boards, but cannot say that I have "done a lot" with 
them, I have some of the 900MHz LoRa boards. They use Cortex M0 and have 
decent amounts of flash and memory.

Here is the 433 MHz version here, was reading a bit the other day about 
some HAM folks using it.

AFIAK LoRa is not approved for HAM use yet ?? Once it is the 
possibilities are boundless, the radio chips they are using work in a 
far wider frequency range than the finished boards do, all about 
matching antenna networks ??

As to the Blue Pill (STM32 ?) a friend is messing with them quite a bit 
bare metal programming

Mostly I just fiddle around, typically never create a finished 
projection/application that stays powered up and running ;-).

Playing with one of these right now :-).

The ESP8266 are pretty cool with built in wifi......but kind of flaky.

The Raspberry Pi ZeroW may be the best thing going right now really for 
$9.99, once folks get to working bare metal with them instead of using 
applications running on top of an OS.
