BRD1: common questions
What microcontroller does the BRD1 use?
The BRD1 is built around the SEEED ESP32-C3, from the ESP32 family.
How big is the BRD1 PCB?
The BRD1 measures 70 × 70 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BRD1?
10 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the BRD1 design files?
From the mFulmini/engineer repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the BRD1 design in my own project?
The repository has no license, so all rights stay with mFulmini. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BRD1 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.
