Note: The YL-105 typically maps the 8-pin connector of the NRF24L01+ into a more linear and easily understood 6-pin or 8-pin header pattern, often marking pins like VCC and GND clearly on the board. 4. Why Use the YL-105? (Advantages)

The YL105 is NOT suitable for PWM (Pulse Width Modulation) or rapid switching. Use a solid-state relay (SSR) for high-frequency control.

The LM393 output is open collector. The datasheet usually notes this, meaning you can pull it up to a different voltage (e.g., 3.3V for a Raspberry Pi) than the module’s VCC (5V). This is a major plus for mixed-voltage systems.
– 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.
For convenience, I recommend downloading the and the PC817 datasheet separately, then combining their specifications—that is effectively the YL105’s complete technical documentation. Note: The YL-105 typically maps the 8-pin connector

– Choose a tubing size where the supplied I.D. comfortably fits over your cable bundle, and the recovered I.D. is smaller than the cable diameter to ensure a tight fit after shrinking.

completely prevents this hazard by stepping down the voltage through its AMS1117-3.3 regulator. 2. Resolving Power Insufficiency
