## Overall (mm)

| length | width | height |
|---|---|---|
| 110.1 | 89.13 | 15.8 |

**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.

## Notes

- PCB 110.0 × 84.0, 1.6 thick, board bottom at 0. Power/heater terminals on one short edge, EXP1/EXP2 LCD headers on the other; USB, SD and the ESP32 antenna on one long edge, stepper connectors on the other.
- Four Ø3.2 mounting holes on a 102.0 × 76.0 rectangle, 4.0 in from each edge.
- Tallest part: the pluggable power terminal block, 15.8 above the board bottom; screw terminals 11.65, EXP headers 10.75, driver sockets and motor connectors 8.65.
- The SD card overhangs the board edge by 5.13 (89.13 overall), the micro-USB by 1.11 and the ESP32 antenna by 1.82.
- Not modelled: plug-in stepper driver modules and heatsinks (they add height above the driver sockets), capacitors, small 2-pin headers and pin tails under the board.
- All dimensions are exact nominal millimetres, true size, with no tolerance added.

## Mating features (exact size; open press / slide / run / socket by your process clearance, leave designed and clamp as drawn)

| feature | exact | mates with | fit | files |
|---|---|---|---|---|
| Mounting holes | 4 × Ø3.2 on 102.0 × 76.0 | M3 standoffs in an electronics enclosure | designed | all |
| Driver sockets | five pairs of 1×8 female rows, tops 8.65 above board bottom | plug-in StepStick drivers (A4988, DRV8825, TMC2209) | designed | all |

## Questions

**What is the MKS TinyBee hole pattern?**

Four Ø3.2 holes on a 102 × 76 mm rectangle, 4 mm in from each edge of the 110 × 84 mm board.

**How tall is the MKS TinyBee?**

15.8 mm to the top of the power terminal block, without plug-in stepper drivers fitted.

**Does anything stick out past the TinyBee board edge?**

Yes: the SD card by 5.13 mm, the ESP32 antenna by 1.82 mm and the micro-USB by 1.11 mm.
