E-Ink Display Console

thingiverse

This is a small, battery-powered display console designed for easy use. Main components: * 2.9 inch 296x128 E-Ink E-Paper Display Module * ESP32 Lolin board * Three buttons * LiPo 3.7V rechargeable battery **Important Safety Notice:** LiPo batteries pose a significant fire risk. Always test the charge and discharge behavior of your chosen battery before using it. Purchase high-quality products only, and never use damaged or bloated LiPo batteries. Regularly inspect your device for any signs of malfunction, and never leave it charging unattended. Remove the LiPo battery when not in use and store it safely to prevent accidents. **Functionality:** I'm utilizing this console to control various home automation features using three soft keys that activate different functions. The ESP32 enters deep sleep mode most of the time but wakes up every minute to update the current time or responds to a button press. Communication with my central hub is established through Bluetooth Low Energy (BLE), which enables efficient power consumption. A 1000mAh battery should last approximately ten days on a single charge, considering only one-minute updates for the clock display. The buttons are soldered at specific locations on rows 2 and 4 and columns B/G, K/P, and T/Y. **Bill of Materials (BoM):** * LOLIN32 V1.0.0-ESP32 * Waveshare 2.9 inch 296x128 E-Ink E-Paper Display Module - Black and White version to allow partial updates * LiPo battery with a two-pin JST-PH connector * 2x8 cm PCB (Printed Circuit Board) * Three 12mm x 12mm PCB push buttons * Three button caps, each measuring 12mm in diameter * Dupont jumper wires - Optional for those who prefer not to solder the buttons directly. The display module should be shipped with a set of Dupont connectors. * Screws and nuts for assembly. **Additional Resources:** For detailed design specifications and further information on this project, please visit https://www.thingiverse.com/thing:2789144
