Liangshanpai smart car motherboard

This project refers to the smart car motherboard designed based on the smart car design scheme of the Lichuang Liangshan School development board.
Functions include tracking, camera collection, Bluetooth, remote control, etc. . . Note: I drew two versions of the smart car motherboard. The wiring of the first version (V1.1) was a bit messy. After laying out the signal lines and power supply, I couldn’t route them, so I changed it to a 4-layer board. I felt unsatisfied, so I drew another one. version (V2.1).
           In the second version, in order to reduce the board size, the tracking circuit module is drawn separately on another board (V2.2).
V1.1 (first edition): V2.1 (second edition): V2.2 (tracing circuit):

 In the end, due to the quality problems of the purchased components and the purchase quantity Due to the shortage, the impact of the epidemic on express delivery, and early school holidays, the functions currently implemented are limited to obstacle avoidance and tracking (the tracking is not perfect). The relevant effect video is in the attachment. Of course, since the time is up, I have to finish the project first. Later, I will continue to improve the tracking and develop other functions.
