You can build a remote-controlled car with a Raspberry Pi Zero, but the board variant matters: the original Zero has no built-in wireless connectivity, while the Zero W and Zero 2 W include Wi-Fi and Bluetooth. For either a donor RC car or a custom chassis, keep motors off the Pi’s GPIO pins and use a motor driver matched to the motors. The chassis, motors, battery and desired features determine the rest of the build.
Choose a build route before buying parts
There are two practical starting points: adapt an existing RC car or build a car around a custom chassis. Raspberry Pi’s project coverage includes both an RC-toy adaptation that uses a Pi Zero and wireless radio with a controller for an Arduino-powered custom Lego car, and a custom 3D-printed remote-controlled car featured in the contents of Raspberry Pi Official Magazine issue 155 (July 2025).
| Consideration | Adapt an RC donor | Build a custom car |
|---|---|---|
| Vehicle mechanics | Reuses the donor’s chassis, steering and drivetrain where they are suitable. | Requires you to select or fabricate the chassis and arrange steering and drive components. |
| Mechanical effort | Can reduce fabrication, but the vehicle may need modification to fit electronics. | Includes chassis design or assembly as part of the project. |
| Control electronics | May let you interface with existing controls, or require replacing them; inspect the donor before deciding. | Lets you choose the control electronics, but you must provide the motor-control path. |
| Repairability | Depends on the donor’s parts and how accessible its mechanisms are. | Depends on your design and the availability of replacement or fabricated parts. |
| Camera or payload | Space and mounting options depend on the donor vehicle. | Can be planned into the chassis, subject to size, weight and power constraints. |
These are planning trade-offs, not measured performance comparisons. Choose based on the parts you already have, your fabrication experience and whether you want to preserve the donor’s controls.
Pick the right Raspberry Pi Zero
“Raspberry Pi Zero” describes boards with different connectivity and assembly details. Raspberry Pi’s hardware table lists no wireless connectivity for the original Zero; the Zero W and Zero 2 W have 2.4 GHz single-band 802.11n Wi-Fi and Bluetooth. Raspberry Pi lists Wi-Fi at 35 Mb/s for both models, with Bluetooth 4.0 BLE on Zero W and Bluetooth 4.2 BLE on Zero 2 W. These are published specifications, not a guarantee of the car’s range or real-world network speed. See Raspberry Pi hardware documentation.

For straightforward network control, choose a W model. With a non-W Zero, plan a separate communications module or radio link; do not assume the board can connect to Wi-Fi by itself. Before buying, verify the exact model and whether it has a soldered GPIO header. The original Zero’s header is unpopulated, and some other Zero boards are also sold without one. If the board lacks a header, allow for soldering or a compatible header solution before wiring.
Plan the motor driver and power around the actual motors
Raspberry Pi’s hardware documentation states: “Do not connect motors directly to the GPIO pins, instead use an H-bridge circuit or a motor controller board.” A GPIO pin is for control signals, not for supplying motor power. Use a driver suitable for the motors and the control signals in your design.

The title alone does not specify motor voltage, stall current, chassis, battery or runtime, so there is no universally compatible driver or battery choice. Before wiring, check the motor specifications and confirm that the driver’s voltage and current ratings suit them. Then choose a battery and power arrangement appropriate to the motors, driver and Pi; do not assume the motor supply can be selected independently of the rest of the build.
Add a camera only if the project needs one
A camera is optional. If you add a Raspberry Pi camera to a Zero, the board uses a mini 22-pin CSI connector, so you need the correct Standard-Mini camera cable. A standard camera cable does not fit this smaller Zero connector. Check the camera and cable connector types against the Raspberry Pi camera documentation before ordering.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Plan the control path before assembly
At a high level, the control path is: a remote device sends commands over the chosen wireless link, software on the Pi interprets them, and the Pi signals a motor driver to control the motors. The driver—not the GPIO pins—handles the motor connection. Decide whether your build will use a network connection or a separate radio link, then select parts and software for that route. The available project examples establish viable directions, but do not prescribe a universal wiring diagram or software configuration for every chassis and motor combination.
