Hi there I am not talking about the Phizer blue pill
I am taking the STM Electronics 32bit micro controller development boards
Which you can program using the Arduino IDE
That have more memory and have more accurate A/D converters 12bit instead of the 8bit analog inputs of the Arduino Atmel chips
This also has 12bit D/A analog outputs for HIFI outputs
These micro controllers are smaller than the Arduino UNO
Like the Teensy but with more festures has a few
RTC real time clocks
And a lot more features
