Notes

Bobricius DIY keyboard build around a separately purchased Heltec WiFi LoRa 32 V3. The Tindie offer is a $26.23 passive PCB, with an optional $4.97 cover; switches, beeper, headers, power switch and the radio board are separate.[1] Keyboard/UI features require the seller’s custom firmware; standard Heltec V3 firmware does not provide the custom keyboard interface. The seller tested this design with V3 and says it is not ready for V4. This record covers the V3 design, not the T114 keyboards also sold under similar HelSenger/MeshSenger names.[1][6][5]
