STC32G12K128 Development Board

Classic straight-in connector! Wide range of peripherals! Beginner-friendly!

I. Project Overview

    This project uses the STC32G12K128 Beta-IDIP40 chip as the main controller. Compared to the classic 89C51/89C52, this chip offers more code space and richer on-chip peripheral resources. The board size is 10x10cm, and it extensively uses through-hole component packages, paying homage to the classics with a strong postmodern cyberpunk archaeology feel. With abundant onboard peripherals and every pin on the chip utilized, it is particularly suitable for beginners to learn about 51 core hardware and practice soldering techniques. The average cost per board is under 35 RMB (price referenced from the July 2024 market, calculated by averaging the total cost of 5 development boards and then adding a 150% premium), making it an excellent choice for beginners and training.

II. Resource Introduction


Main Control Chip: STC32G12K128 Beta-IDIP40
Power Supply Overview: Except for the WiFi interface which uses 3.3V power, all other devices use 5V power from USB output. Download
and Debugging: One USB-to-serial port (P3.6/P3.7) for debugging, one USB download interface
. Onboard Peripherals:
8-digit LED
passive buzzer,
universal screen interface (compatible with IIC bus and SPI bus screens)
, CAN communication interface,
infrared receiver,
1-channel ADC acquisition (optional light intensity or potentiometer),
temperature and humidity acquisition (compatible with DS18B20 and DHT11),
4-digit LED display (74HC595 driver)
, 4-digit LED display & 4*4 matrix keypad (TM1650 driver).
4 independent buttons (KEY1 can be used for downloading simultaneously)
WiFi communication interface (ESP01S)

III. Usage Instructions: Ready to use
immediately after opening the package. Do not insert into 51 microcontrollers, as the pins are incompatible. Please refer to the datasheet.
IV. Attachments:
I've been a bit busy lately, so I just wrote a simple LED display. See the video later for the effect. The Keil project is at the end. Updates to other onboard peripheral examples will be after December 24th, 2024. See you later!

Mobile phone screen auto-clicker

The simplest mobile clicker combined with a control panel enables a game of liking and playing piano tiles.

The simplest mobile phone clicker, combined with a control board, enables a "like" and "piano tile" game.
You can buy a PUBG-like suction cup (available on Taobao) to play; the principle of GND conduction and high-level disconnection achieves double-tap likes.
A video demonstration can be viewed on my Douyin account. The accompanying clicker control board is also open-source in my projects.

Location and Communication Services Module

Location and 4G communication service module compatible with ZTE E610

This replica of the location and 4G communication service module common to the ZTE E610 eliminates the need for soldering the impedance matching circuit and CH32 microcontroller circuit during replication; the 485 jumper can be directly connected. This results in a smaller size and easier portability.

Low-power PWM output

Temperature control PWM, used in chassis or indoor applications

In the sweltering summer heat, when camping outdoors, a cool breeze is essential. This project, based on a 51 microcontroller, controls two channels of PWM wave output and allows for adjustable wind speed via Bluetooth control. Bluetooth commands are sent as: auto (automatic mode) and game (full-speed mode). The video shows it installed in the host computer case.
