1. Introduction
GD also produces memory. Currently, the company uses GD25Q256E memory. This memory is relatively small and very suitable for our current products. It adopts QSPI communication mode. To
I read Huawei's data, which says that the selection of the two capacitor values before and after the Pi-type filter is as follows: the DC capacitor is 10UF, and the AC capacitor is 0.01 to 1UF. I don'
