In recent years, the real-time positioning technology of mobile vehicles based on GPS system and GSM wireless communication network has developed rapidly and is widely used in public security, fire pr
I developed a device using omap, using a USB interface, setting the USB device to self-powered, and setting the maximum current to 100mA. After plugging it into a PC, it can get 300mA of current and c

Introduction: When the ADN2812 uses the default working mode (i.e. locking to the input data mode), it can automatically lock to the input data mode without programming and external reference clock as
1-3. Input and output matching circuit
The purpose of the matching circuit is to choose a way of acceptance. For those transistors that want to provide greater gain, the way is to accept and output it
