WL500B from WL, in a SOP-8. 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 pin (接地管脚). |
| 2 | ANT | input | RF signal input pin for 300-440 MHz wireless reception (RF 信号输入脚). |
| 3 | VDD | power_in | Power supply pin, operating voltage DC 2.0-5.5V (电源管脚，DC 2.0~5.5V). |
| 4 | NC | unconnected | No connect/floating pin (悬空). |
| 5 | DO | output | Demodulated data signal output; output disabled when continuous high level exceeds 8ms (解调数据信号输出). |
| 6 | SHUT | input | Work mode selection pin; connect to power for shutdown mode, ground for working mode (工作模式选择脚). |
| 7 | SQ | input | Squelch selection pin; apply power or leave floating to enable squelch, connect to ground to disable squelch (静噪选择脚). |
| 8 | RO | input | Reference oscillator input pin for external crystal oscillator connection, input impedance 290 kΩ (外接晶振管脚). |
