A Bluetooth-controlled 3D-printed micro car built around an ESP32-C3. It uses a 3V brushed DC motor for drive, a 9g servo for steering, a DC–DC 5V regulator to power electronics, and a motor driver to control the drive motor. The car demonstrates compact electronics integration, basic RC control over BLE, and rapid prototyping with Onshape + 3D printing.

Key features

Control: Bluetooth (BLE) via ESP32-C3 Drive: 3-12V brushed DC motor + driver Steering: 9g servo Power: battery(3.7V) + 3.7 to 5 V Stepup for both motors Mechanical: 3D-printed chassis (Onshape model linked) Extras: photos of current print and CAD model
