Follow this precise mapping scheme to interface your hardware cleanly without sacrificing communication stability:
The NRF24L01+ is strictly 3.3V tolerant. Supplying 5V to the VCC pin of the NRF24L01+ will burn it out. The YL-105 solves this safely.
When building wireless sensor networks, IoT nodes, or remote control systems using microcontrollers like Arduino, STM32, ESP8266, or ESP32, developers frequently encounter power-supply and wiring complexities. The nRF24L01+ module requires a strict but pulls peak current bursts during radio transmission that standard microcontroller 3.3V pins cannot safely handle.
Monitoring voltage thresholds to prevent overcharging. Troubleshooting Tips yl105 datasheet
While overwhelmingly associated with Alpha Wire's heat shrink tubing, it is worth noting that the "YL-105" designation appears in other unrelated, niche products. Some search results may point to an "YL-105" as a component in a remote control infrared alarm system, with specifications including a 6V DC power supply, 105dB alarm sound, and a detection range of 3 to 5 meters. Additionally, there are "YL105" sensors, such as the SRWQ100-YL105-9001, a water quality sensor for residual chlorine.

| | Likely Cause | Solution | |-------------|------------------|---------------| | Relay does not click | No power on VCC | Check 5V and GND connections. | | Relay clicks but load doesn’t turn on | Wrong wiring (NC vs NO) | Load should be connected to COM and NO. | | Random toggling | Floating input pin | Use a pull-down (active HIGH) or pull-up (active LOW) resistor (10kΩ). | | Microcontroller resets when relay activates | Power supply insufficient | Relay coil draws ~80mA. Use a separate 5V supply for module. | | Jumper setting ignored | Poor contact | Remove/insert jumper multiple times or solder the desired connection. |
