Supply chain troubleshooting
⚠️ In case a few componenets are not available refer to the list below:
- 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%)
Design
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.
Cyberpunk
A cyberpunk alike robot is cold as hell. The low poly edges also make it easier to print.
