README
README.mdSimple ESP32 Notifier
This is just a simple board to hold a Heltec WiFi Kit 32 ESP32 dev kit.
The board works for either the V2 or V3 boards, but require different pin definitions due to the different pinouts of the boards. Pin definitions can be found in pinDefs_V2.h and pinDefs_V3.h.
This Heltec board comes with a built in 0.96 OLED screen that is used for showing notifications, and the board adds 3 LEDs and 3 Buttons.
As this board is designed to be simple it just uses through hole components and uses one GPIO pin per LED and one per button.

Questions
How big is the Simple esp32-notifier PCB?
It measures 60 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Simple esp32-notifier use?
13 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Simple esp32-notifier KiCad files?
From the HBoyd255/simple-esp32-notifier repository on GitHub, at the commit this page was made from: the board is hardware/SimpleESP32Notifier.kicad_pcb and its schematic hardware/SimpleESP32Notifier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Simple esp32-notifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask HBoyd255 before reusing the design.
