Riotee probe is an open-source printed circuit board by NessieCircuits, from the NessieCircuits/Riotee_ProbeHardware repository on GitHub, published under the CERN-OHL-W-2.0 licence. It is a 4-layer board of 43.2 × 22.9 mm with 74 parts on 86 nets, routed with 469 tracks and 144 vias.
It is built around the RP2040, W25Q16JVUXIQ and 74LVC2T45GT, with the TLV73333PDBV, TPS71721DCK and TS5A3166YZP among its other parts. Its parts include 28 capacitors, 27 resistors, 9 ICs, 4 connectors and 2 diodes. It belongs with the sensors and measurement boards and the RP2040 boards of this library.
The Riotee probe lets you program a Riotee module that is soldered onto your PCB or plugged into a breadboard. It has a standard 10-pin 0.1" connector compatible with the popular Tag-Connect cables that allow in-circuit debugging with a very small footprint.

Specification:
The probe has a dedicated controller (Raspberry Pi RP2040) that manages the upload of new firmware to the Riotee device as well as the communication with a PC. The firmware running on the RP2040 is hosted in this repository. To upgrade the firmware on the Riotee probe, connect a wire from one of the ground pins to the test pad labelled 'USB_BOOT' on the bottom of the board, while plugging in the USB cable. A removable storage drive should appear on your PC. Drop a UF2 compatible binary into the drive.

74 parts, built around the RP2040, W25Q16JVUXIQ, 74LVC2T45GT and TLV73333PDBV. 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.
From the NessieCircuits/Riotee_ProbeHardware repository on GitHub, at the commit this page was made from: the board is kicad/riotee-probe.kicad_pcb and its schematic kicad/connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
