If the sub 6GHz 5G network is likened to expanding a single-lane highway in an old city, then millimeter wave 5G is equivalent to building a new four- to eight-lane highway in a new city.
Compared wit...

I use stm32f103, UART11 57600,8,1,N.When using it, I occasionally find that the communication stops, but it works normally after reset. Because the speed is relatively slow in the design, I use Wanli'...
StartFragmentI would like to ask, what should be connected in the middle of the signal coming out of the I/0 port of stm32, and then connected to the relay (such as a 24v relay)...
I recently made a board that requires many I/O ports, but the chip I chose at the beginning does not have many I/O ports, so I want to make a NIOS core in the FPGA and send data to the nios through th...
