I saw in the documentation that the supply voltage range of LM124 is 3~30V, but when I was debugging the board, I found that when the supply voltage of LM124 was changed, the output voltage would chan...
The Bluetooth ceramic antenna I bought has a theoretical center frequency of 2.45G, but the test result is 2.7G. The callback loss near 2.45G is very poor, but the finished device works normally (the ...
Let's see if the solution is feasible by using STM32 to communicate with MIPI module. Attached is the data format of MIPI, including read and write. I originally wanted to use PIC18F to do it, and use...
