1. The core board of the car is the Liangshan School GD32F407ZGT6 development board, which is purchased directly from Jialichuang, so no welding is required. All components of the expansion board are hand-soldered, so the appearance is a bit ugly.
2. It is recommended that components be welded sequentially from small components to large components, from patches to plug-ins, to prevent individual large components from blocking small components and making it inconvenient to weld.
3. Since I haven’t found a suitable battery holder yet, I put a sponge pad on the board and then tied it with a tie.
4. After the board is welded, you need to adjust the tracking probe, put black electrical tape on the floor, power the car, and align the probes one by one with the black wires. If the indicator light does not light up, adjust the corresponding potentiometer counterclockwise until the corresponding The LED lights up. The appropriate degree is that when the probe is aligned with the black line, the LED lights up. After the offset, the LED does not light up.
