16*16 dot matrix screen driver board

Overview

With a 16*16 SMD LED dot matrix screen, of course, a matching driver board is needed. The size of the driver board is consistent with the dot matrix, and the hole positions of the pin and female headers also correspond one to one.
The board integrates a usb to ttl program download port and uses the HT42B564 module solution verification.
The control chip uses STC89C52RC microcontroller.
The main power supply is expected to use a CR2302 two-position battery box with a diode connected in series to make the battery output voltage drop below 6v.

Differences between 74 series circuits and CMOS series circuits
Not long ago, I needed to design a timing circuit with a delay of 5 seconds. The design idea was finalized, but there was a problem during the experiment. The following figure is the circuit that need
Selection and Differences of Isolated Oscilloscopes and Differential Probes
Sometimes it is dangerous to use an oscilloscope to measure a circuit system with a potential difference. This danger may come from a short circuit inside the device or from the potential itself. As t
