Many GPIOs of SAM R21 support PWM output function, so it is also very easy to implement the breathing light function. You only need to change the duty cycle of the PWM output periodically to change th
What are the basics of Power over Ethernet ( PoE )? The IEEE 802.3af standard for PoE requires that all data terminal equipment (DTE) receive power using the same cabling as data, which specifies 48V
This article takes RFID products that use magnetic coupling and CMOS technology as an example to briefly introduce the composition of such chips. Based on the listing of various destructive/non-destru
What is a DC-DC converter? In fact, it is a voltage converter that effectively outputs a fixed voltage after converting the input voltage through a DC-DC converter. Generally, DC-DC converters are div
