Riskybirdv3: common questions
What microcontroller does the Riskybirdv3 use?
The Riskybirdv3 is built around the ESP32-C6-MINI-1/U, from the ESP32 family.
How big is the Riskybirdv3 PCB?
The Riskybirdv3 measures 58.3 × 58.3 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Riskybirdv3?
172 components, from 76 distinct parts. The full bill of materials is listed on this page.
Where can I download the Riskybirdv3 design files?
From the ucb-bar/riskybird repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Riskybirdv3 design in my own project?
The repository has no license, so all rights stay with ucb-bar. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Riskybirdv3 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.
