I was looking everybody’s favorite online store for Atmega32u4 based MCUs for a friend and stumbled upon this little guy:
It sure as heck isn’t a 32u4 but it is rather interesting !
It looks like it’s an esp8266 module in the form factor of an arduino pro micro, I’m a bit put off by the $20~ price tag but it would be interesting to see if they have routed the pins to the corresponding ones as for the pro micro.
Then you could use it as a drop in replacement without even having to change the code, except you would suddenly have the option to add wifi to your project!
IoT is definitely getting much easier these days to implement than when this blog first started! Hahaha
No more fumbling around with an Arduino Uno with Ethernet and then little dodgy radios talking to other Unos with the same radio…..
Oh man that was hell
