MySensors D1 mini is derivative of Sensebender Micro designed by Thomas Mørch (thomas@mysensors.org). Main goal of this project is to use all Wemos D1 mini (pro) shields with MySensors node.
Node is flashed with MySbootloader 1.3, info is here: https://forum.mysensors.org/topic/4991/mysbootloader-1-3pre2-testing
Update 2017-04-21: added DHT22 sketch and picture.
Update 2017-04-19: uploaded pics of first prototype and source code of relay node.
You can order PCB from following two sources:
- PCBs.io 4 for $6, black 1.6mm PCB
- OSHPark.com 3 for $7.60, purple 1.6mm PCB
