The PCB for my Raspberry Pi RC car controller is finally done.

Routing is finished, the 4-layer board has been checked in 3D against the Raspberry Pi 3, and the files are now sent to JLCPCB.

Next step is assembling it and finding out what I missed 😅

Routing has started on the 4-layer PCB for my RC car controller.

L1 and L4 are used for signals, L2 is kept as a solid ground plane and L3 handles power. Still plenty of routing left, and I’ll probably question some of my component placement choices before it’s done.

Work in progress.

PCB design is full of small decisions that turn out to have a much bigger impact than expected.

Currently routing the controller board for my RC car project and spending way too much time deciding where the connectors should go. They need to be easy to access and logically grouped, but also not turn the routing around the MCU into a complete mess.

Still a work in progress. Curious how other people approach this. Do you place connectors first and route around them, or let the routing decide?

Did I miss something? I think I finally have all features in the schematic now:
- Power supply 3.3V
- Power supply 5V/3A (for Rpi)
- 4 AD inputs
- 4 generic outputs
- 4 RC servo outputs
- on-board temperature sensor
- External NTC interface (measure DC motor temp)
- Hall sensor input to measure motor speed
- I2C bus for external battery current sensor
- Buzzer

Phew... it is getting crowded on the board now...

Work in progress! Building a custom STM32 controller board for my internet-controlled RC car.

The STM32 handles the real-time hardware: 4 RC servo/ESC outputs, analog inputs, general-purpose outputs, IÂČC and a buzzer. It communicates with a Raspberry Pi over UART, while the Pi handles the camera, web interface and internet connection.

Still designing and testing, so things will probably change along the way!

Small engineering improvements matter as much as big new features.

Not every update is visible, sometimes the biggest win is improved reliability.

Today’s change: the video stream is more resilient to transmission errors, making the RC platform more stable in real-world conditions.

What invisible improvement has made the biggest difference in your projects?

An old RC car + Raspberry Pi 3 + Lovable = ❀

Now I need to stabilize the power to the RPi so itbis not restarted when given full throttle

Adding support to control my WLED ESP8266 based nodes directly from the dashboard.

Lots of useful features on my dashboard. Although the UI is created using Lovable I run a local webserver on my RPi4 to render the page (mainly for security reasons). A deployment script reads from the git repository shared with Lovable and publish it to the web server. Very convient!
