Better — Yl-105 Datasheet

typically refers to a specialized VCC Adapter Board designed to power the popular wireless transceiver module. Makerlab PH The most critical "solid feature" of this board is its on-board AMS1117-3.3 voltage regulator

Understanding the pinout is essential. The YL-105 module typically exposes four pins (or a 4-pin header): yl-105 datasheet

Below is an informative paper summarizing the specifications, pinout, and application of the YL-105 module. 🛰️ Device Overview typically refers to a specialized VCC Adapter Board

1. GND: Ground (Connect to MCU Ground)
2. DATA: Digital Output (Connect to MCU Input Pin)
3. DATA: Digital Output (Same as pin 2, often used for external LED indicator or tied together)
4. VCC: Power Supply (5V)
