Brightside - for my second version of an esp32 SPUD GUN tank.

Since somyone really cares about this project, I made it more readable ：） This board contains: Motor Drivers: Contains two l298n to drive two 550 motors, each chip allows 2A current, and 550 motor uses up to 3A current, that's why I made this special board to drive them. I fit the most common heatsink just onto these chips, CHECK if it fits your heatsink. They are critical. Servo: Two servo outputs, for my suspension, or your turrets. Power: Apply 12V to drive motor and 5V to drive mcu & l298n VSS. If you use other voltages, remember to insert into the '12V' socket, even if it is just 5V!! Relay Module: Contains 2 relays, each with a BC547 transistor, for the weak esp32 io cannot directly drive them. Connected to PIN 22 and 23. I've changed the risisters to fit this 3.3V mcu, using 3.3V logic, the relays are still powered by 5V. All of the components are DIP, SMT is a little difficult for me, I made a variant using VNH5019, and messed it up.. For this one, I tested, all work great. I use the relays to control alcohol pump & ptc resister & zvs module. Would you like to see my arduino code for this? I also made an android app to control my tank, by bluetooth. The whole project will be uploaded onto youtube before Oct ends, It is a cool one! Soon...I hope
