The video focuses on several basic elements and concepts about batteries. First, it introduces what fuel measurement technology is, and explains the intrinsic relationship between shutdown voltage, discharge rate, temperature and battery age. Then four main battery-related definitions were listed: battery chemical capacity (Qmax), availability (Quse), and battery internal resistance, including three factors that affect internal resistance performance—state of charge (SOC), temperature, and aging. The relationship between the degree and the remaining battery capacity (RM).
I am working on the wireless transmission of sim900 and need to upload a picture file of about 60kb to the server. I use TCP transparent transmission and find that the speed is too slow. I want to ask
I am a sophomore, and I am working on a research project with several classmates at school, mainly wireless sensor networks. The content is roughly to detect the open and close status of the door, and
CC2640 R2 is a low-power wireless MCU launched by Texas Instruments for Bluetooth Smart applications. The chip runs TI's BLE protocol stack and has the characteristics of low power consumption, rich p
I knew when I was a kid that books are the ladder of human progress. So how many books do you, as electronic engineers, read every month? Please vote and let us mortals see the gap between us and the

In PCB design, the signal transmission delay on the bus is agreed to be greater than (1/6) the digital signal rise time tr≤6tpd, then such a signal is considered a high-speed signal and produces a tra
