WH-LTE-7S1

USR IOT · 2G/3G/4G/5G Modules · DIP-24

WH-LTE-7S1 from USR IOT, in a DIP-24. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 LINKA output Indicates whether the first network connection (Socket A) is established, outputting high level when connected and low level when not connected.
2 LINKB output Indicates whether the second network connection (Socket B) is established, outputting high level when connected and low level when not connected.
3 USB_DM bidirectional USB D- data line (I/O).
4 USB_DP bidirectional USB D+ data line (I/O).
5 V_PAD power_in 3.0V IO power domain.
6 UTXD1 output UART transmit pin, sending data from the module to the user device at 3.0V level.
7 URXD1 input UART receive pin, receiving data from the user device into the module at 3.0V level.
8 VBUS power_in USB power supply pin.
9 WORK output Module working indicator that toggles between high and low every 1 second (blinking) after normal startup.
10 POWER KEY input Module power on/off control, where a low level powers the module off.
11 GND power_in Module power supply negative (ground).
12 GND power_in Module power supply negative (ground).
13 DCIN power_in Module power supply positive, 5-16V.
14 DCIN power_in Module power supply positive, 5-16V.
15 NET output Network status indicator pin.
16 VCAP power_in Alternative supply input to DCIN (use one or the other, never both at once), supply voltage 3.4-4.2V with 3.8V recommended.
17 NC unconnected No connection.
18 RELOAD input Restore-factory-settings pin, effective when pulled low for 3s to 15s.
19 RESET input Module restart/reset input, active low.
20 VSIM power_out SIM card power supply pin.
21 SIM_DAT bidirectional SIM data line (I/O).
22 SIM_CLK bidirectional SIM clock line (I/O).
23 SIM_RST output SIM reset/control output.
24 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: WH-LTE-7S1
  • Footprint: Package_DIP:DIP-24_W7.62mm
  • 3D model: DIP-24 (KiCad packages3D, STEP)
  • 3D model files: wh-lte-7s1-etched.step / wh-lte-7s1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); wh-lte-7s1.step / wh-lte-7s1.glb are the bare package body.

Provenance

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

  • Datasheet: USR IOT datasheet (41 pp, sha256 03a54aeaaf005ae8, retrieved 2026-11-02, 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: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
