When we design single-chip electronic circuits, we often use the following commonly used circuits. We need to redraw them every time, which is laborious and troublesome, and prone to errors. Therefore
It is quite good, and it is related to the 2440 development board. If you don't have this development board, you don't need to download it, it's all from actual operation [url]http://www.embedsky.net/
I bought an LSM303DLH magnetic field sensor module online and planned to use the CH579M-R1 development board to drive it. Here is a photo of the module:There are 8 pins on the module, 4 of which are u
With the continuous progress of society and the development of the Internet of Things, the outdoor application scenarios of electronic products have continued to grow at a high rate. Electronic produc
Soldering surface for printed circuit boards: HAL lead-free
The HAL lead-free soldering surface provides the best solderability on all surfaces, but the thickness of the tin layer varies.In "HAL Lead
