When ordering the BOM, make sure to order at least 5 (five!) of each component so you end up with the possibility to solder 5 different PCBs.
- Any ESP32-S3-WROOM-1 (NOT 1U!) should work. There are a few variations of the same footprint with more or less RAM and FLASH.
- H1-H4 componenets are mount holes, they don't need any component assigned.
- In case of resistor or capacitors shortage, it is also OK to find other supplier as long as it follows the same specification (e.g. 20k resistor 5%)
The design of the BattleButBot plays an important role. How it is designed determines how heavy (or how light) it is. Two requirements: sturdy and light.
A cyberpunk alike robot is cold as hell. The low poly edges also make it easier to print.
What you need:
- 6 M3 8mm/5mm screws
- 6 Heat inserts
- The body
- The lid
- The front
- A 2S-7.4V Battery
- The PCB
- The two wheels
Place the battery close to the front of the bot.
Place the switch.
Place both motors with the gears facing the top (to prevent any friction with the bottom).
Before screwing the PCB down, finish all the connections.
Place the PCB and the lid, and screw it down.
Clone the project by running the following command:
