ESP8266 WeMos D1 Mini WIFI

For less than AU$10 I picked up ESP8266 ESP-12 ESP-12F CH340G CH340 V2 USB WeMos D1 Mini WIFI Development Board for curiosity.

Deployment turns out to be fairly easy … the hardest bit was fixing the Arduino IDE on OS X Big Sur … and with 11 IO pins it could quickly become a useful device
Getting started

iokit = ctypes.cdll.LoadLibrary('/System/Library/Frameworks/IOKit.framework/IOKit')
cf = ctypes.cdll.LoadLibrary('/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation')

The example works as advertised (remember to use 115200 baud)
