DC-34-Badge: common questions
What microcontroller does the DC-34-Badge use?
The DC-34-Badge is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.
How big is the DC-34-Badge PCB?
The DC-34-Badge measures 145.2 × 203.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DC-34-Badge?
87 components, from 31 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 DC-34-Badge design files?
From the Cyber-Professionals-Enthusiast-Club/DC-34-Badge 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 DC-34-Badge design in my own project?
The repository has no license, so all rights stay with Cyber-Professionals-Enthusiast-Club. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the DC-34-Badge 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.
