: Connects directly to the 5V power output pin of your development board. GND : Connects to the system Ground (GND) rail.
All YL105 models are manufactured by , a leading global producer of wire, cable, and heat shrink tubing. Alpha Wire maintains ISO 9001 certification and is known for products that meet stringent military (MIL), UL, and CSA standards.
As explained, "YL" = Yellow, "105" = Packaging: 4-foot piece. Arduino and NRF24L01 : 6 Steps (with Pictures)
AMS1117-3.3V (steps down 5V to the 3.3V required by the nRF24L01+). Output Voltage: Stable 3.3V to power the radio module. Operating Current: Typically peaks around 12–15mA during transmission. Connectivity: 2x4 female header for plugging in the nRF24L01+. Input Pins:
Aris slammed the datasheet onto the table. “YL105. NPN Silicon Phototransistor. ” He read the lines aloud, as if they held a secret.
