: SPI data transmission line from MCU to radio. Pass-through to the radio.
Use the YL-105 adapter to safely power the nRF24L01 from 5V. Connecting the 3.3V nRF24L01 chip directly to 5V will likely destroy it. yl105 datasheet
: The board incorporates surface-mount ceramic bypass capacitors across both the input and output rails. These capacitors act as local reservoirs of electrical charge. They eliminate the voltage dips and high-frequency ripples that cause transmitter resets during rapid RF power state changes. : SPI data transmission line from MCU to radio
This F3003/4 YL105 provides a significantly thicker wall than the general-purpose series, ensuring high dielectric strength and excellent mechanical durability for demanding applications like automotive, marine, and industrial machinery. Connecting the 3
