Hardware (Per Gate)
| Item | Quantity | Note | Cost (AUD) |
|---|---|---|---|
| ESP32 S3 SuperMini | 1 | (Just about) Any ESP32 is going to work. The supermini's are just adorably tiny, inexpensive, and relatively easy to come across from a range of vendors. The Supermini range also has an onboard WS2812 LED (GPIO48), meaning gate status can be indicated (red = closed, green = open) with the included LED. Other supermini variants except H2 (no wifi) should work just fine, you will just need to adjust the code slightly. |
~$5.50 |
| DFRobot DSS-P05 | 1 | most likely any other servo of the same size will work here | ~$12.00 |
| USB-C Breakout Board | 1 | See alternative power wiring below | ~$0.50 |
| M4 x 8mm | 4 | To hold the motor in place | ~$0.20 |
| M4 Hex Nut | 4 | To hold the motor in place | ~$0.10 |
| M5 x 16mm | 4 | Holds the gate housing together | ~$0.60 |
| M5 Heatset Insert | 4 | To hold the gate housing together | ~$0.70 |
| Hall Effect Sensor | 1 | To detect tool power on/off | ~$?? |
| Remote Trigger | 1 | To manually open/close the gate. See remote options below. | ~$?? |
