BitForge-Nano: common questions
What microcontroller does the BitForge-Nano use?
The BitForge-Nano is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the BitForge-Nano PCB?
The BitForge-Nano measures 55 × 120 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the BitForge-Nano?
183 components, from 58 distinct parts. The full bill of materials is listed on this page.
Where can I download the BitForge-Nano design files?
From the WantClueTechnologies/BitForge-Nano repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the BitForge-Nano design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which WantClueTechnologies chose for the repository.
Can I test firmware for the BitForge-Nano 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.
