DoE Flame Effects Receiver

 

In Collaboration with the Dragons of Eden and Illumination Village, we have created the first revision of a standardized wireless controller for Flame Effects Devices. While it’s targeted at flame effects, it’s also a robust and inexpensive platform for other IoT use cases.

Power Management

  • 9-18vdc input
  • Double regulated power rail for the uC and Voltage References
  • 3.3vdc and 5vdc onboard regulators
  • Header for external Lithium Ion battery and charger.
  • Regulated power supplies are isolated and buffered from surges of the unregulated supply.

Status Display

  • Display header can be used for either two common LED status outputs (max 10ma, ea) or an array of hundreds of APA102 SPI connected RGB LEDs.

Output Header

  • 1x 10pin, 8 Output header – Direct Drive
    • Sink 500ma per pin (Via Darlington Array)
    • LED status lights on each output
    • Enough drive current to operate fairly large solenoids or relays
    • Built in flyback diodes to drive inductive loads
  • 1x 10pin, 8 Output Header – General Purpose
    • Pins are 1:1 mapped with the Direct Drive header
    • Unregulated output
  • 1x 10pin, 8 Output Header – Special Purpose
    • These pins expose the special functions of the controller and may be shared elsewhere on the board.
    • Regulated 3.3vdc & Unregulated output

Input Header

  • 1x 10pin, 7 Input General Purpose Header – Protected
    • 0.01uf Capacitor and 10k Pull Up to for debouncing and ESD protection
    • 100ohm Series Resistor to limit surges
    • Regulated 3.3vdc & Unregulated output
  • 1x 10pin, 7 Pin Header – Special Purpose
    • These pins expose the special functions of the controller and may be shared elsewhere on the board.
    • I2C 
    • Regulated 3.3vdc & Unregulated output

Wireless Connectivity & uC

  • The DoE Receiver is built on top of the ESP32 by Espressif.
