Datasheet [work]: Yl105

Note: While the nRF24L01+ transceiver requires a strict 3.3V supply on its VCC pin, its data pins (CE, CSN, SCK, MOSI, MISO) are 5V tolerant. This allows you to route SPI signals safely from a 5V microcontroller through the YL-105 without external logic level shifters. Why the YL-105 Is Necessary 1. Preventing Transceiver Damage

: Ensures clean power delivery for environmental monitoring systems and automated lighting arrays.

Includes the AMS1117-3.3V IC for stable power. Voltage Input: Accepts 4.8V - 12V DC input. Output Voltage: Stable 3.3V DC. yl105 datasheet

: Irradiated polyolefin (PO), which is flame-retardant and fluid-resistant. Shelf Life

(Note: Although the VCC line requires 5V to run the regulator, the nRF24L01+ logic pins are . This means you can run the SPI data lines directly from a 5V microcontroller without logic-level shifters). Schematic and Circuit Breakdown Note: While the nRF24L01+ transceiver requires a strict 3

Connect to Arduino Digital Pin 11 (Hardware SPI MOSI).

While cost-effective, the YL-105 has distinct limitations that engineers must account for: Preventing Transceiver Damage : Ensures clean power delivery

While the adapter itself (YL-105) serves as a power interface, its performance is tied to the voltage regulator usually found on the board:

The YL105 family comes in a variety of inner diameters to accommodate different cable bundles.
