t1601b.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

T1601B

Mysentech · Temperature and Humidity Sensor · SOT-23-3

T1601B from Mysentech, in a SOT-23-3. 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 GND power_in Ground reference for the device. Assumed standard SOT23-3 1-Wire temperature sensor pinout - not explicitly enumerated in the supplied application guide.
2 DQ bidirectional 1-Wire data and power line. Open-drain bidirectional bus (typ. 4.7 kΩ pull-up to VDD). Carries all commands (Read temperature 0xBC, Read scratchpad 0xBE, Write config 0x4E, Read romcode 0x33, Copy page 0x48, Recall EE 0xB8, etc.) between host and device.
3 VDD power_in Supply voltage input, 1.8 V to 5.5 V. Typical measurement current 2 µA at AVG=8, 1 Hz. Decouple to GND with 100 nF close to the pin.

CAD (KiCad official)

  • Symbol: T1601B
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: t1601b-etched.step / t1601b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); t1601b.step / t1601b.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
t1601b.step 59 KB You want the bare part, or you mark your own boards.
t1601b-etched.step 1.2 MB You want the part with T1601B already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 289 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 (6 pp, sha256 e08608d6a042684f, 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.
