Yl-105

The YL-105 serves as a bridge between a 5V power source and the 3.3V requirements of the nRF24L01+ module. Most Arduino boards provide both 5V and 3.3V rails; however, the 3.3V rail often lacks the current capacity to handle the peak power spikes during wireless transmission, leading to failed data packets or "frozen" modules.

The YL-105 is a low-power, radio-frequency identification (RFID) based electronic lock designed primarily for secure storage solutions. It is manufactured predominantly by specialized smart lock OEMs in China (often marketed under brands like or generic white-label branding). The device is engineered to replace traditional mechanical cam locks in environments requiring keyless entry, auditability, or temporary access control, such as gyms, offices, schools, and hospitals.
