# Adafruit PiCowbell boards and Pico cases > What are PiCowbell dimensions for the Raspberry Pi Pico? - Category: Electronics › Microcontroller boards - Kind: Modern device - Basis: Adafruit CAD (MIT); PiCowbells match the Pico outline 51 × 21 mm and its Ø2.1 mm holes on 47 × 11.4 mm - Page: https://xemstudio.com/objects/adafruit-picowbell-pico-accessories/ · JSON: https://xemstudio.com/api/geometry?object=adafruit-picowbell-pico-accessories · Plain text: https://xemstudio.com/objects/adafruit-picowbell-pico-accessories/sheet.txt - License: dimension sheet CC BY 4.0 (Xem Studio); linked files under their publishers' licenses ## Notes - PiCowbell (Proto, Adalogger, DVI, Camera, Terminal…): 51 × 21 mm, the Pico's four Ø2.1 mm holes (47 × 11.4 mm pattern), mounts under the Pico on 2.54 mm headers; stack height about 10–12 mm board to board. - DVI and Camera PiCowbells extend past the outline for the HDMI socket / camera connector; see the bounding boxes. - The Pico case (6252) is Adafruit's printed case design for the bare Pico. ## Sizes | product | bbox_l_mm | bbox_w_mm | bbox_h_mm | |---|---|---|---| | 5200 Proto PiCowbell | 53.2 | 20.3 | 5.1 | | 5703 PiCowbell Adalogger | 52.1 | 20.3 | 5.6 | | 5745 PiCowbell DVI | 52.2 | 20.3 | 4.9 | | 5945 PiCowbell Camera | 52.9 | 20.3 | 7.4 | | 5907 Terminal PiCowbell | 52.7 | 43.2 | 12.0 | | 5905 Proto PiCowBell | 53.2 | 38.1 | 5.3 | | 5906 Proto Doubler PiCowBell | 67.3 | 53.3 | 6.4 | | 5967 Proto Tripler PiCowBell | 96.5 | 53.2 | 6.4 | | 6363 PiCowBell HSTX DVI | 52.1 | 20.3 | 5.0 | | 6252 Pico Case | 56.0 | 42.0 | 11.6 | ## Where the files are - Adafruit (official): [Adafruit_CAD_Parts: STEP, Fusion 360 and STL for Adafruit products](https://github.com/adafruit/Adafruit_CAD_Parts) — STEP, F3D, STL — MIT ## Free STEP/STL (10 parts, MIT License (Adafruit_CAD_Parts), Adafruit Industries) Index: https://xemstudio.com/files/adafruit/adafruit-picowbell-pico-accessories/index.json - 5200-proto-picowbell: [STEP](https://raw.githubusercontent.com/adafruit/Adafruit_CAD_Parts/main/5200%20Proto%20PiCowbell/5200%20Proto%20PiCowbell.step) · [STL](https://raw.githubusercontent.com/adafruit/Adafruit_CAD_Parts/main/5200%20Proto%20PiCowbell/5200%20Proto%20PiCowbell.stl) — Adafruit #5200 Proto PiCowbell;
