The chip ferrite beads BLM series is designed to work nearly as a resistor at noise frequencies, which greatly reduces the possibility of resonance and leaves signal wave forms undistorted.

After using wince5 on mini2440 board to connect wireless network card, I found that the wireless network card was not started after restarting. I need to unplug the USB plug and plug it in again to co...
Can someone please help me see if this circuit diagram is correct? And what are the appropriate values of resistors and capacitors? A novice among novices needs help...
As of today, I have written some debugging codes. I found another software bug. The delay timer does not work properly, but the motor can rotate at high speed. Is it considered hard commutation? Howev...
1. What is our project? In layman's terms, this project is to install an Internet cafe in the hotel, and the computers are not concentrated in a lobby, but are scattered in the hotel rooms to provide ...
The chip model of the board is MSP430F2618. There were always problems with the calculation and collection of data before. Later, it was found that it was the floating point data processing. For the c...
1. If the MCU has a serial port peripheral, plus a level conversion chip, such as MAX232, SP3485, it is an RS232 and RS485 interface.2. RS485 uses differential signal negative logic, +2~+6V represents...
