Even with the YL-105, ensure your Arduino can supply enough current. If using PA+LNA modules (high power), ensure the power supply is robust.
Using the YL105’s own dark current vs. temperature graph on page 3 of the datasheet, Aris calculated the exact bias resistor needed to ignore the red LEDs. He added a tiny, black heat-shrink tube over the phototransistor—the datasheet’s mechanical drawing showed a 5mm diameter, perfect for a light pipe—to act as an optical bandpass filter. yl105 datasheet
The technical parameters outlined in the YL-105 module datasheet include: Specification Note / Context Can accept up to 7.0V max depending on the LDO variant. Output Voltage 1.9V to 3.6V DC Configured out-of-the-box to supply precisely 3.3V . Onboard Voltage Regulator AMS1117-3.3 IC Industry-standard LDO capable of handling up to 800mA peak. Quiescent / Operating Current 12.3 mA typical Scalable based on the underlying nRF24L01+ TX/RX state. Form Factor Dimensions 26mm x 19mm x 12mm Even with the YL-105, ensure your Arduino can
