E002 rocker: common questions
What microcontroller does the E002 rocker use?
The E002 rocker is built around the ESP32-S3-WROOM-1-N8R2, from the ESP32 family.
How big is the E002 rocker PCB?
The E002 rocker measures 56.5 × 216 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the E002 rocker?
213 components, from 56 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 E002 rocker design files?
From the oscar-wik/e002_rocker 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 E002 rocker design in my own project?
The repository has no license, so all rights stay with oscar-wik. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the E002 rocker without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
