STC32G12K128-LQFP64 Minimum System Board

Overview

The main controller uses two chip packages: STC32G12K128-QFN64 and LQFP. The appropriate chip can be selected for PCB fabrication and soldering.

It has 64 I/O ports.
An onboard 5V to 3.3V converter provides 5V, GND, and 3.3V outputs for easy power supply to external modules.
The board includes one power LED, one user LED
, two user buttons, one normally closed power switch, and one normally open download/reset button.
A serial port interface is provided.
A Schottky diode is added to the 5V input of the Type-C interface to prevent current reversal.
Hardware USB download is used. Pressing the reset button and then powering on via USB...

Re-understanding of analog ground and digital ground
In order to achieve good anti-interference, we often see ground splitting wiring on PCB boards. However, not all digital circuits and analog circuits must be split on the ground plane. Because this sp
Problems with CRect and RECT
If I assign a CRect object to a RECT object, will there be any problems? For example, if a function parameter is of type RECT, but a CRect object is passed in as a parameter, will there be any problem
Matrix keyboard
Why when I turn on the switch when scanning the matrix keyboard, it always displays 0, which is the number of the keys in the first row and first column. It should display nothing. I can't figure it o
【MicroPython】MicroPython mini board has arrived
I received a call from the courier today. I guessed that MicroPython had arrived, but it didn't turn out! 1. The packaging is anti-static, which is very considerate2. In addition to the small board, i
I'm touched. It's great to have a video tutorial.
Yesterday I watched MSP430, the step-by-step video operation. Very detailed. It turns out that there are many things I don't understand about stm32. After watching the msp430 video tutorial. I underst
The higher the frequency of electromagnetic waves, the farther they can be transmitted.
I've heard people say before that the higher the frequency, the greater the attenuation; recently I saw that "the higher the frequency of electromagnetic waves, the longer the transmission distance".
