STC89C52RC/STC12 core board

Overview

1. All IO ports are led out, among which P0~P3 adopt a double row of pin design, which can be arranged in one row upward and one row downward to meet various needs. All pin headers are accurately positioned and can be directly inserted into perforated boards and breadboards.
2. USB-C can be used for power supply, and the CC pin has a 5.1k resistor pulled down to GND to ensure that all charging heads can be recognized normally. In addition, you can also use an external power supply and plug it into the VIN and GND pins next to the USB port.
3. The board comes with a set of 3.3V power supply (horizontal blue pin header), 5V power supply and GND. There are also reserved external interfaces (yellow and black horizontal pin header).
4. The serial programming port is led out separately (vertical blue pin header). Needle)
5. Using 3225 crystal oscillator, it is smoother and more beautiful.
6. All P0 ports have reserved pull-up resistor pads on the back of the PCB.

Circuit Design Simulation Problems
I am designing a high-frequency data acquisition analog circuit recently. I would like to ask you experts, which simulation software has a richer component library and is easier to use? ADS? Multisim?
802.11n Information
As the title says, this document mainly describes 802.11n. Well, it means the quality is good.
