m1601w.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 3 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

M1601W

Mysentech · Temperature and Humidity Sensor · SOT-23

M1601W 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 input. Operating range 1.8V to 5.5V (absolute max -0.3V to 6V). Typical supply current 0.1µA idle (single-shot mode), 4.8µA average at 1 measurement/s, 450µA peak during conversion.
2 DQ bidirectional 1-Wire single-bus digital interface (open-drain). Requires external pull-up resistor (typ. 4.7kΩ, 1kΩ recommended for long cables or multi-drop). Carries all ROM/function commands, temperature data, and CRC. VIL ≤ 0.3·VDD, VIH ≥ 0.7·VDD, VOL ≤ 0.4V @ IOL = -3mA.
3 GND power_in Device ground reference. Connect to system ground plane.

CAD (KiCad official)

  • Symbol: M1601W
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: m1601w-etched.step / m1601w-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); m1601w.step / m1601w.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
m1601w.step 59 KB You want the bare part, or you mark your own boards.
m1601w-etched.step 1.1 MB You want the part with M1601W already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 273 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 (29 pp, sha256 ecdd68f8f5232fc5, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
