Yl105 Datasheet «LIMITED — 2024»

: Optional pin to alert the MCU when new data arrives. 2. Female Socket Output (To nRF24L01+ Module)

The serves as a vital voltage-regulation and interface adapter designed specifically for the popular nRF24L01+ 2.4GHz wireless transceiver module . Because standard microcontrollers like the Arduino UNO provide 5V logic signals and power lines, connecting them directly to a sensitive 3.3V nRF24L01+ chip frequently causes transmission failures or permanently destroys the radio module.

The YL-105 integrates a voltage regulator and filtering components to stabilize communication. Specification 5V DC (Accepts range 4.8V – 12V) Output Voltage 3.3V DC (to power the nRF24L01) On-board Regulator AMS1117-3.3 chip Max Output Current Up to 800 mA Compatibility 8-pin nRF24L01+ or nRF24L01+ PA+LNA modules Operating Temp -40°C to +125°C Dimensions 26 x 19 x 12 mm 2.

Controlling multi-speed settings or sleep timers.

If the jumper is installed, the relay activates when IN = LOW. The wiring is identical, but logic is reversed.
