LR690L from Feng Niao RF, in a SOT-23-6. 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 | XTAL | passive | Crystal oscillator connection; external crystal frequency selected per FOSC = FRF/32 (÷1/32), e.g. 9.81563 MHz for 315 MHz or 13.52127 MHz for 433.92 MHz RF. |
| 2 | GND | power_in | Power supply negative (ground); 0 V reference for all internal circuits. |
| 3 | SHUT | input | Shutdown control input, active-low; low level = normal operation, open or high level = sleep mode (ISTBY = 0.3 μA typ). |
| 4 | DATA | output | Demodulated ASK/OOK data output; logic level follows received signal envelope, data rate up to 10 kbps. |
| 5 | VDD | power_in | Power supply positive; operating range 2.0 V to 5.5 V (typ 3.3 V); working current 2.8 mA at 315 MHz, 2.9 mA at 433.92 MHz (3.3 V), sleep current 0.3 μA. |
| 6 | ANT | input | RF signal input; connect to antenna via matching network; sensitivity −110 dBm (ASK/OOK), spurious reverse isolation −20 dBm, ANT pin impedance RSC = 50 Ω. |
