Figure 1Figure 2Figure 1 is a BUCK circuit, connected to a 500 ohm load, AI4, AI5 are the return detection signals, AI4, AI5 are divided and passed through the operational amplifier, and the value aft
I finally rewrote the driver of ov7221 and successfully captured the image, but the image is not very clear. I don't know if it is related to the 30W pixel.
The key problem is that the camera has a ve
This is my first time drawing a PCB. When I tested it, I found a strange problem. If the input PWM signal is 5kHz, there is no problem. But if it is higher, 15kHz, it is always at a low level. No matt
I feel very good after getting this board. I think it should be the best domestic development board I have ever used.
The board is small in size and compact in design, and can basically meet the commo
