README.mduart2ble_oled
- UARTを受信し、OLEDおよびBLEに送信するArduinoプログラムです。
- ESP32C3 XIAO用に作成されています。nrf52840用もありますが飛距離が最大15m程度なのでTFでは使えません。
- リレー以外にはOLEDに表示する機能もついています。UART -> XIAO(ESP32C3) -> SSD1306 and BLE.
- 受信のUARTは38400Baud. OLED(SSD1306)とはI2Cで通信する。
- UARTで受信したデータのうち、#で始まる文字列のみを、BLE Nordic UARTで送信する。
- MacBookAirで受信してPythonでグラフ化するコードも公開しています。ble_plotterはこちら。
- 詳細情報が欲しい方はメールからどうぞ。

Questions
How big is the Uart2oled ble PCB?
It measures 43 × 24 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Uart2oled ble use?
10 parts, built around the R-78E5.0-0.5. 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 Uart2oled ble KiCad files?
From the MasaoC/uart2ble_oled repository on GitHub, at the commit this page was made from: the board is kicad-data/uart2oled-ble.kicad_pcb and its schematic kicad-data/uart2oled-ble.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Uart2oled ble 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).
