Ultra-compact footprint optimized for space-constrained builds. 2x4 Female Header (8-Pin) Direct drop-in match for standard nRF24L01+ RF modules. Input Connection Pins 6-Pin Male Header Exposes Power (VCC/GND) and the hardware SPI bus.

– Use a heat gun (not an open flame). Heat evenly around the tubing until it shrinks tightly onto the substrate. The minimum shrink temperature is 90 °C; full recovery occurs at 121 °C for the FIT‑221 series and 140 °C for the FIT‑300 series.

The YL105 heat shrink series is a versatile solution found across many industries:

The YL105 is typically available in a small package, such as a SOT-23-5 or a SOP-8.

, meaning you can usually connect them directly to a 5V Arduino without needing additional level shifters. Instructables or a specific code library to get your communication started?

When you plug the nRF24L01 module into the YL-105, the pins map as follows: Pin 1 (GND) →right arrow YL-105 GND Pin 2 (VCC) →right arrow YL-105 regulated Pin 3 (CE) →right arrow Pin 4 (CSN) →right arrow YL-105 CSN Pin 5 (SCK) →right arrow YL-105 SCK Pin 6 (MOSI) →right arrow YL-105 MOSI Pin 7 (MISO) →right arrow YL-105 MISO Pin 8 (IRQ) →right arrow YL-105 IRQ Wiring Guide: Connecting to an Arduino Uno Connecting the Go to product viewer dialog for this item.

: SPI Pin initialization signal. Pass-through to the radio.

The module includes dedicated pass-through trace channels for standard hardware data lines. Because the nRF24L01+ inputs are natively 5V tolerant, these logic paths pass uninhibited through the YL-105 without requiring active logic-level conversion ICs: MOSI (Master Out Slave In) MISO (Master In Slave Out) SCK (Serial Clock)

This is the #1 cause of nRF24L01 failure. Even though the YL-105 regulates the voltage, if your Arduino is powered via a standard USB port, it might not provide enough current for continuous transmission. Try using a separate power supply or breadboard power module.
