Page Turner

Page Turner is a battery-powered ESP32 development board, with a lightweight set of sensors connected to an e-Paper display.

Block Diagram

Goals

  • Low-power operation with 6+ mo on a coin-cell battery
    • 20 cycles per day
    • Min 4 cycles per day refresh to avoid burn-in
  • Small form-factor
  • Low cost BOM (will be distributed at tradeshows)
    • $15 @ ~100 qty cost target
  • Temperature + humidity sensing and reporting
  • Header pins available to extend the sensor suite to additional external sensors

Extended Goals

  • External DC power input
  • Extended operating temperature (for outdoor weather monitoring)
  • Physical enclosure
