Espressif ESP32-S3-DevKitC-1 v1.1 — board outline, module overhang, dual USB-C and header rows
What are the ESP32-S3-DevKitC-1 dimensions and where are the USB-C ports and module? · Modern device · basis: Espressif's ESP32-S3-DevKitC-1 v1.1 DXF and PCB layout PDF (2022-04-29), with module size from the ESP32-S3-WROOM-1 datasheet.
Also called: esp32-s3-devkitc-1, esp32 s3 devkitc, esp32-s3-devkitc-1 v1.1, esp32-s3-devkitc-1-n8r8, esp32-s3-devkitc-1u, esp32 s3 devkit dimensions, maker esp32
Exact dimensions. Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part. Mating features

Notes
- Exact nominal dimensions. PCB 25.40 × 62.87 × 1.60 mm, square corners; datum is the lower-left PCB corner at (0, 0), bottom on z=0, USB-C end at y=0.
- No mounting holes: the board is held by its two 2 × 22 header rows (2.54 mm pitch) or in a breadboard.
- ESP32-S3-WROOM-1 module 18.00 × 25.50 × 3.10 mm at x 3.75–21.75, y 43.64–69.14: the antenna end overhangs the board edge by 6.27 mm (overall length 69.14).
- Two USB-C receptacles 8.20 mm wide, 3.20 mm tall, at x 1.90–10.10 and 15.30–23.50, y 1.03–6.30.
- Header pins project about 6 mm below the board: leave that clearance underneath. Not modelled: pins, buttons, LED and small parts.
