This is my First RC Tank

Hopefully i have provided enough info for people to get creative and making it! The controller was a PS2 controller to Arduino, I have provided the code and circuits / PCB so that should be enough. As for the motherboard in the tank i have provided the gerber files, BOM, Firmware (Atmel Studio) and detailed PDFs.

As for the tank it uses 4 stepper motors, so 2x a4988 drivers are needed.
A battery from hobby king, I'm using a 2800mAh and i get 2 hours from it.
80mm fan
10mm steel balls (for the bearings)
various size bolts and nuts (all M3)
2mm solid core wire to join track treads
the quantities are on the part names.

NOTE!!!!!! You can either use a gearbox for each stepper motor or not use one at all, if you use one then only use files labels gearbox, if you don't, ignore them.

Comment if you have any questions

Enjoy!
