LR670L from 蜂鸟无线, in a SOT-23-6. 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 | RO | passive | Crystal (reference oscillator) pin; the datasheet lists the function as crystal (晶振), with a 13.52127 MHz crystal frequency for 433.92 MHz. |
| 2 | GND | power_in | Power ground. |
| 3 | SHUT | input | Mode select input: 0 = operating mode, 1 = shutdown mode (standby current 0.3 µA typ. with VSHUT=VDD). |
| 4 | DO | output | Data output, CMOS level. |
| 5 | VDD | power_in | Positive supply, 3.5 V to 5.5 V (typical 5 V). |
| 6 | ANT | input | Antenna input (RF), specified with a 50 Ω source resistance. |
