IoT Calendar: Creating A Custom Featherwing

I wanted to create a few projects interfacing an e-paper display with the Adafruit HUZZAH 8266 and HUZZAH 32. The HUZZAH microcontrollers are a great fit with e-paper displays. In addition to having WiFi connectivity to grab date, weather and calendar information from the internet, they also can power themselves down and wake up at a later time. Since the e-paper displays retain their display without power, this makes for a great symbiotic relationship. Running the HUZZAHs with the e-paper display for just a few minutes each day can allow the device to run for weeks or even months depending on the size of the battery.


In all, I was very happy with the result. I no longer need to hand solder a dozen or so wires on a small proto board and the final product looks very clean. Having the same board compatible with both the HUZZAH 8266 and HUZZAH 32 is an extra bonus. I am putting the finishing touches on the code for a monthly calendar display and name plate/badge that you can see in the photo at the top of this article. This code will be released to GitHub and described in a future article.
