Hi all, I got a 4WD car kit and realized now on assembly I got the wrong version. I was going to use the Raspi 4 with camera for a custom project. What I got instead was the car kit for Pi PICO. It says PICO PRO on the board. Now, all parts of the kit are fine for me otherwise. Can I buy the 4WD Hat separately? Can you point me to a source? Got this one: ![image](https://canada1.discourse-cdn.com/flex029/uploads/sunfounder/original/1X/76ad0ec04f7f258bc3815a0a3b5bd096cf8afa1e.jpeg) but need that one: ![image](https://canada1.discourse-cdn.com/flex029/uploads/sunfounder/original/1X/2b4340f6a7a650121439e93719549b325a3f77e8.jpeg) Any other ideas on how to connect the Pi 4 to my existing kit? ---

regarding the use of the Pico Pi HAT with my Pi 4: Are the GPIO connectors on PICO Pi and Pi 4 equivalent? If so, I should be able to wire up the PICO sockets on the HAT module to the Pi 4´s GPIO connectors. If I then install microPython on my Pi 4 would I be able to read sensors and control motors just the same as when using the Pico? Or is a special driver needed for either platform? ---

The Raspberry Pi interface and driver are not compatible with pico and cannot be used directly. ---
