- CH32V003 RISC-V microcontroller, powered by one AAA cell through a TPS61021A boost converter. - Three SK6812MINI-E RGB LEDs: the flying car's headlights, and the fingerprint scanner indicator. - Four self-blinking LEDs: the tower spire and the geodesic sphere. - Two capacitive touch pads: the fingerprint, and Lil Chompy's head. - SAO connector: the badge is an SAOv3 host on I2C, and GPIO1/GPIO2 carry a 115200-baud…

2026-badge: common questions
What microcontroller does the 2026-badge use?
The 2026-badge is built around the CH32V003F4P6, from the RISC-V family.
How big is the 2026-badge PCB?
The 2026-badge measures 92 × 63.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 2026-badge?
28 components, from 16 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 2026-badge design files?
From the bsidesorlando/2026-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 2026-badge design in my own project?
The repository has no license, so all rights stay with bsidesorlando. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the 2026-badge without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
