WS480X from wisesun, in a SOP-8. 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 | GND | power_in | Ground pin for the receiver IC. |
| 2 | ANT | input | RF signal input pin; saturation input level is -20 dBm with RSC = 50 Ω. |
| 3 | VDD | power_in | Supply pin with an operating range of DC 2.0 V to 5.5 V; absolute maximum is 5.5 V. |
| 4 | CTH | input | Selects the reference signal mode for the internal data comparator; CTH source impedance is 145 kΩ. |
| 5 | DO | output | Demodulated digital data signal output. |
| 6 | SHUT | input | Shutdown control: connect to VDD to shut down and to GND for normal operation; SHUT pin low to receive start time is 3 ms. |
| 7 | NC | unconnected | Not connected; leave floating. |
| 8 | REFOSC | input | External crystal connection; the pin can also be driven by an external reference clock through a coupling capacitor with a peak-to-peak amplitude of 0.3 V to 0.7 V. |
