BitaxeUltra: common questions
What microcontroller does the BitaxeUltra use?
The BitaxeUltra is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the BitaxeUltra PCB?
The BitaxeUltra measures 56.5 × 99.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the BitaxeUltra?
85 components, from 44 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 BitaxeUltra design files?
From the bitaxeorg/bitaxeUltra 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 BitaxeUltra design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which bitaxeorg chose for the repository.
Can I test firmware for the BitaxeUltra 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.
