README

Devices that can communicate state to one another.
Project uses a Raspberry Pi Pico W, a Lora antenna, TP4056 lithium-ion cell charger to transmit a selected phrase. This selected phrase is picked up by another module and displayed.
All firmware code is written in micropython.
Todo:
- Wifi communication
- LoraWAN communication
- Pickup firmware
What would I do differently:
- Add USB-B port somewhere
- Add buzzer
- Move 18650 holder a bit higher

Questions
How big is the Wasbeer communicator PCB?
It measures 83 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wasbeer communicator use?
21 parts, built around the E22-900M22S, TP4056 and DMG2302U. 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 Wasbeer communicator KiCad files?
From the FunDeckHermit/hw-communicator repository on GitHub, at the commit this page was made from: the board is Wasbeer-communicator.kicad_pcb and its schematic Wasbeer-communicator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wasbeer communicator design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
