: Connect to 5V power (External or Microcontroller 5V pin). GND : Connect to common Ground.
RC-Switch (ideal for generic remote controls) or VirtualWire / RadioHead (for custom data packets).
The YL-105 is a 5V to 3.3V voltage regulator adapter board designed to facilitate stable operation for the nRF24L01+ wireless module with 5V microcontrollers, utilizing an on-board AMS1117-3.3 regulator. It features an 8-pin interface for the module and provides necessary power stability to prevent signal issues. For full specifications and purchasing, visit MakerLab PH Instructables
The YL-105 controller module features four pins for easy integration with microcontrollers like Arduino, Raspberry Pi, or ESP32. Connects to power supply. GND: Ground connection. yl-105 datasheet
The nRF24L01+ module is notoriously sensitive to power issues. When using 5V systems, connecting the module directly to 5V will burn it out. Using the 3.3V pin on an Arduino frequently provides unstable power, leading to erratic wireless communication. The board provides: Safe Voltage: Proper 3.3V regulated power supply.
: Emits a piercing 105dB alarm to deter intruders.
: The recovered wall thickness is vital for mechanical protection and insulation. : Connect to 5V power (External or Microcontroller 5V pin)
A voice—not audio, but felt—rippled through his mind: “Hello? Is anyone there?”
The 8-pin female socket directly replicates the nRF24L01+ layout. When the transceiver is inserted into the YL-105 socket, the regulated 3.3V power is delivered cleanly to the module's VCC pin. The SPI control lines ( SCK , MOSI , MISO , CSN , CE , IRQ ) pass directly through the adapter to the host MCU. Schematic and Circuit Architecture
All he had was a partial PDF header: “YL-105 Dual-Factor Biometric Bridge – Preliminary Datasheet v0.9.” The YL-105 is a 5V to 3
The YL-105 shines in projects requiring low-power, low-cost wireless links:
The YL-105 is a rugged, high-pressure transducer often utilizing stainless steel diaphragms designed for measuring gage, absolute, or differential pressure in liquids and gases. Due to its robust construction, it is frequently used in environments with high temperatures and high media compatibility needs. Key Features and Benefits
