Build it yourself
Electronic Cats publish the full CatSniffer v3 KiCad project (schematic, PCB, libraries, 3D STEP) and 3D-printable enclosures in their own repo under CERN-OHL v1.2.

git clone https://github.com/ElectronicCats/CatSniffer.gitResearch notes
Verified via gh api tree + blob fetch (200) and by grepping the downloaded files. hardware/ holds a full KiCad project (.kicad_sch/.kicad_pcb/.kicad_pro, lib tables, .pretty footprints, board STEP); the repo root LICENSE.md is CERN-OHL v1.2; cases/ holds 3D-printable enclosures (STL/STEP/3mf). The KiCad source is the v3 board: it has RP2040 + SX1262 and the PCB title block reads rev 'v3.2' (the schematic title block still says '2.0'). TRAP: hardware/CatSniffer.pdf is a stale v2 export (SAMD21E18A + CC1352P1F3RGZT, 'Rev: 1.0'), so it was deliberately left out; export a fresh PDF from the .kicad_sch instead. The KiCad CC1352 symbol is named CC1352P1F3RGZT, while v3 ships a CC1352P7 in the same VQFN-48 RGZ package. Confirm the fitted part against a real unit before ordering. No standalone Gerbers are committed; generate them from the .kicad_pcb. Last hardware/ commit was 2025-01-15 ('Update

What still needs checking
- The product page gives inconsistent firmware-license labels; verify the license in the particular repository/release.
- The store’s weight and dimensions appear to be erroneous or packaging fields; physical board dimensions need confirmation.
