README
Readme.mdPicoTag – Hardware Overview
PicoTag is a compact hardware reverse engineering and interface discovery board powered by the Raspberry Pi Pico W. It is designed for embedded developers and security researchers who need to scan, probe, and interact with unknown hardware interfaces like JTAG, SWD, SPI, and UART. The board routes 16 GPIOs for flexible digital analysis, integrates a flash dumper interface, and supports a built-in terminal experience via USB.

Questions
How big is the PicoTag PCB?
It measures 63 × 59.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PicoTag use?
90 parts, built around the TF-015 and WS2812B-2020. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PicoTag KiCad files?
From the ril3y/picotag-hardware repository on GitHub, at the commit this page was made from: the board is PicoTag.kicad_pcb and its schematic PicoTag.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoTag design in my own project?
Its repository states no licence, so its author keeps all rights: ask ril3y before reusing the design.
