: No soldering or external voltage dividers are required; it is a "plug-and-play" solution for wireless projects.
: It features an onboard AMS1117 3.3V regulator that converts a 5V input into a stable 3.3V supply. yl-105
The YL-105 is versatile and suited for various sectors: : No soldering or external voltage dividers are
, you connect the adapter's pins to your microcontroller. Note that while the power is regulated to 3.3V, the of the nRF24L01+ are 5V tolerant, meaning they can be connected directly to an Arduino Uno's digital pins. Pin Connections VCC : Connect to 5V on the Arduino. GND : Connect to GND on the Arduino. CE / CSN : Connect to any digital pins (e.g., D7 and D8). Note that while the power is regulated to 3
Based on the designation , this typically refers to a specific model of an Electronic RFID Cabinet Lock widely used in the furniture and access control industry.
The lock generally supports Mifare 1K S50 cards and compatible FOBs. It usually supports "Master Card" management, allowing a single supervisor card to unlock all locks in a facility while individual user cards work only on assigned lockers.
