M1601B

Mysentech · Temperature and Humidity Sensor · SOT-23

M1601B from Mysentech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive supply voltage input. Operating range 1.8 V to 5.5 V (absolute max −0.3 V to 6 V). Typical supply current is 0.1 µA idle (single-shot mode) and 4.8 µA average when measuring at 1 sample/s.
2 DQ bidirectional 1-Wire single-bus data I/O. Open-drain / tri-state; requires an external pull-up resistor to VDD (typ. 4.7 kΩ, range 1 kΩ to 10 kΩ; 1 kΩ recommended for long cables or multi-drop). Carries all ROM, function, temperature-read, and alarm-threshold traffic between the host and the sensor.
3 GND power_in Ground reference (0 V) for the supply and the 1-Wire signal.

CAD (KiCad official)

  • Symbol: M1601B
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: m1601b-etched.step / m1601b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); m1601b.step / m1601b.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
m1601b.step 59 KB You want the bare part, or you mark your own boards.
m1601b-etched.step 1.2 MB You want the part with M1601B already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 296 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Mysentech datasheet (28 pp, sha256 aeda39d8ec9e0fa0, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
