E-Label board
Budget: $300 – $350 USD
I want to develop an E-Label board based on ESP32, similar to the one in the link below, but battery powered (rechargable over Usb) and one RGB-LED
Priority:
- Lowest thickness.
Considerations:
- ESP32 will normally be on DeepSleep mode (~10 µA) and will wake on WiFi event (upload QR/EAN13/Text) on the EPD display.
- Estimated updates per day: 5
- Battery should ideally last several months.
- Battery must be rechargable over Usb.
Delivery:
- You will deliver 3 full working boards (EPD, ESP32, rechargable battery, RGB-LED, enclosure). The price of the materials is NOT included in the price of the project, so it will paid separately as an extra.
- Test functions of the board, written in Arduino IDE, like for example: loadImage(img), clear(), getBatteryLevel(), getMacAddress(), connectToWlan(user, passw), setState(bool), setDescription(str)...
- Web App (very basic), writen in C# or Python, very we can (1) connect over the browser from a PC/Laptop, (2) comission a new E-Label with MAC-Address, (3) request all E-Labels conected now, (4) enable/disable E-Label with MAC xxx, (5) request battery lavel of all E-Labels, (6) request image beeing displayed on E-Label with MAC xxx, (7) Load image on E-Label with MAC xxx, (8) Clear display of E-Label with MAC xxx
- Enable OTA programming for a given E-Label with MAC xxx.
- Provide a 3D-printed enclosure for the boards. There will not be any switch slipping tray for the battery: the enclosure will just expose the display.
- CAD-Schematics for the board and the enclosure, the firmware and the web source code.
Ownership:
- By being granted this project you agree to transfer the full intellectual property and ownership to me.
