ESP8266-DHT22-SR501 kitchen lights thingamabob PCB (#P7F1)

Alright, software aside, back to hardware…

The ESP module shown in #P7 slowly gathers dust in my kitchen, which is tolerable for a few weeks, but that’s not the solution I want long-term. Also, it’s on a separate power brick, meaning there are two microcontrollers running in my kitchen for doing fancy light switches and some air quality logging for twice the standby current. Nope, has to go, needs to be consolidated into one unit.

So a while back I designed this PCB and ordered it (once again) at OSH Park, together with some teeny-tiny DIP adapters that cost next to nothing. […]

I’ve been running the early prototype for quite some while now, doubling as a Blynk gateway to some LED strips in the liquor cabinet (yeah, I called it Boozy McBoozeface for a reason). Accessing lights at home from far away isn’t that important to me, so once I have time to install some more touch buttons, that one will be no longer running Blynk, probably eliminating some timing/connectivity issues.
