I wanted to create a simple stand for the Jet-Engine kit. But i found this one from https://makerworld.com/en/@Yedoggie . I have remodeled it completely to “fit” my standard and i added a little box for an ESP-Controller and a place for a touch-button. The cable tunnels are designed to be printed without support.
To use this with a N20 Motor you will need:
Conversion Kit from @3d_printall : https://makerworld.com/en/models/157767#profileId-206779
Electronic-components used:
GA12-N20-Motor (3V-Version)
ESP32-C3 Mini - controller
TTP223 - touch sensor
DRV8833 - motor bridge
EDIT: Wiring diagram
I have used +5V from a USB Port to power the TTP223-Sensor and the ESP32. To power the DRV883 with the motor, i have connected the VCC from the DRV8833 to the +3.3V output of the ESP. The IO port of the TTP223 is connected to GPIO4 of the ESP and the IN1 of the DRV883 is connected to the GPIO2 of the ESP. The anode of the motor is connected to OUT4 of the DRV and the cathode to OUT3.
