Yl-105 Datasheet

If you need a reliable receipt of signals from standard wireless remotes or sensors, the YL-105 is the superior choice over the cheaper "green board" receivers.

The YL-105 is most commonly known as an adapter module for the NRF24L01 2.4GHz wireless transceiver. It is a utility component designed to simplify the connection between a microcontroller (like an Arduino) and the NRF24L01 radio module. YL-105 Datasheet Overview

The primary function of this module is to provide voltage regulation and a stable power supply for wireless communication.

Regulated Power: Includes an AMS1117 3.3V voltage regulator. This is critical because the NRF24L01 module is sensitive to voltage and operates strictly on 3.3V, while many microcontrollers provide 5V.

Dimensions & Form Factor: A compact footprint of 26 x 18.6 x 10mm and a weight of roughly 3g.

Connectivity: Features an 8-pin socket specifically for the NRF24L01 Wireless Module and a header for easy wiring to a breadboard or MCU. Expert Review & Performance

Based on its technical specifications, the YL-105 is highly recommended for DIY electronics projects for the following reasons:

Stability: Wireless transceivers often experience communication failures due to "noisy" power supplies or current spikes. The YL-105's onboard capacitor and regulator provide the stable current needed for reliable data transmission.

Ease of Use: It eliminates the need for complex voltage divider circuits or external 3.3V power sources, making it a "plug-and-play" solution for beginners.

Safety: It prevents permanent damage to the NRF24L01 module, which can occur if accidentally connected to a 5V power pin without regulation. Alternate Identification

While the adapter is the most common use of the "YL-105" name, it is occasionally associated with other products in different niche markets:

Home Security: A wireless infrared motion sensor alarm model YL-105 exists, typically used in garages or sheds.

Consumer Tech: There is a YL105 mini drone designed for beginners and kids, featuring brushless motors and 8K video.

If you are using the YL-105 Transceiver Adapter, wire it to your microcontroller using this standard mapping:

VCC: Connect to 5V power (External or Microcontroller 5V pin). GND: Connect to common Ground.

CE/CSN/SCK/MOSI/MISO/IRQ: These pins pass directly through to the nRF24L01. Connect them to your SPI pins as required by your library (e.g., RF24 Library for Arduino). Which YL-105 are you working with?

The LM393 does not have built-in hysteresis, but many YL-105 modules add a small positive feedback resistor. Check your board; if not present, you may experience output jitter near the threshold. The datasheet often omits this, so add hysteresis in software (debouncing) or external resistors if needed.

The YL-105 receives raw radio signals. It does not decode them. You need a microcontroller to decode the data. RCSwitch mySwitch = RCSwitch()

Common Library: RC-Switch (ideal for generic remote controls) or VirtualWire/RadioHead (for custom data packets).

Example Code (Using RC-Switch Library):

#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();
void setup() 
  Serial.begin(9600);
  // Receiver is connected to Interrupt 0 (Pin 2 on Arduino Uno)
  mySwitch.enableReceive(0);
Serial.println("YL-105 Receiver Ready...");
void loop() 
  if (mySwitch.available())
int value = mySwitch.getReceivedValue();
if (value == 0) 
      Serial.print("Unknown encoding");
     else 
      Serial.print("Received: ");
      Serial.print( mySwitch.getReceivedValue() );
