STC32G12K128 Development Board

Overview

For the main control chip, this design uses the STC32G12K128 microcontroller, which features high performance and rich peripheral interfaces. To maximize functionality, this development board exposes almost all of the STC32G12K128's full-function pins to meet diverse application needs.
Specifically, the design incorporates the ESP826601S module, which primarily utilizes pins P1.1 and P4.0. When using the ESP826601S module, to ensure its proper operation, pins P1.1 and P4.0 must be kept idle to avoid conflicts with other functions.
Furthermore, this development board integrates the NRF24L01-2.4G wireless communication module, which occupies pins P7.2 to P7.7. When using the NRF24L01-2.4G module for wireless communication, these pins must also be kept idle to ensure communication stability and reliability.
To facilitate debugging during development, this development board also features an OLED display interface, providing developers with an intuitive debugging tool that helps quickly detect and verify system status. This
is my first development board design, and there are many shortcomings; I welcome any corrections or suggestions from experienced developers.

How many Ω is 103KΩ?
For a resistor, 103KΩ is often used to express the resistance value. Some electronic circuit books say that 103K=10 x 10 3 Ω , that is, 10 4 Ω. Some books say that it is 1.0 x 10 3 Ω, that is, 10 3 Ω.
After receiving the information broadcast by the router, the terminal calculates the RSSI, but the data is sometimes normal and sometimes incorrect? ?
