LizardBot1 ProjectFiles: common questions
What microcontroller does the LizardBot1 ProjectFiles use?
The LizardBot1 ProjectFiles is built around the ESP32-WROOM-32E, from the ESP32 family.
How big is the LizardBot1 ProjectFiles PCB?
The LizardBot1 ProjectFiles measures 130 × 90 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the LizardBot1 ProjectFiles?
125 components, from 62 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the LizardBot1 ProjectFiles design files?
From the lizard-electronics/LizardBot1_ProjectFiles repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the LizardBot1 ProjectFiles design in my own project?
