M5Stack Core2 (K010) ESP32 controller: 54 × 54 × 16.5 enclosure and M3 back holes — dimension sheet
Source: Xem Studio, https://xemstudio.com/objects/m5stack-core2/  (sheet CC BY 4.0)
Basis: M5Stack Core2 product size drawing on docs.m5stack.com (54 × 54, depth 16.5, rear holes Ø3.2 on 44 × 44).
Catalog version: 2026-10-20

Overall (mm): length 54.0, width 54.0, height 16.5
- Datum: enclosure centre; back face at 0, screen face at 16.5.
- Enclosure 54.0 × 54.0 × 16.5; corners drawn square because the drawing does not dimension their radius.
- Four Ø3.2 holes in the back face on a 44.0 × 44.0 square, 5.0 from each edge. They are the M3 screws that hold the base and can be used to mount the unit; modelled 4.0 deep (depth not on the drawing).
- Side ports and screen are flush with the enclosure, so nothing protrudes beyond 54 × 54 × 16.5.
- Not modelled: USB-C, Grove Port A, power button and TF-card openings, the rear keyhole slot, the speaker grille and the rear boss and LED.
- Dimensions are exact nominal (true size), no tolerance added.
