Lego DIY SmartCar PCB for an IoT Lab

I'm a Computer Science professor at a University here in Spain. I needed to repair a set of DIY Lego cars within an IoT/SmartCity Lab, that I built 5-6 years ago for academic purposes. They were built using soldering breadboards, using a Raspberry Pis and an Arduino-clone UNO R3 (for each car). Painfully, the Arduino-clones started to die, and finally, only one of the 8 cars were still working. As the Arduino-clones does that I choosed at the begining were not Arduino 'compliant' (very extrange and unknown for me at the moment), reparing them required to reassembly the soldering breadbords ... too heavy! I learnt to build PCBs (It's my first design!), and finally, I ordered them to PCBway. The order was processed very fast, and in 12 days (since I placed the order), I received the PCBs. VERY WELL PACKAGED, AND FAST DELIVERY. THE PRODUCT QUALITY IS AMAZING, THE BOARDS LOOK REALLY NICE AND PROFESSIONAL ... I CANNOT BE MORE EXCITED ABOUT THE RESULT! Without doubt, I will use this service again.
