Ultra World Development Board / Quad-Channel SuperCharge

Project Introduction:
This project is a development board based on the STM32 microcontroller, which can be used, explored, and used for learning STM32.
Project Functionality
: This design is a four-channel ammeter and development board based on the STM32F411 microcontroller. It features five independent buttons with functions RST, BOOT0, KEY1, KEY2, and KEY3, a reserved program download interface, seven I/O ports, one serial port for connecting to a host computer, four input C ports, and four output C ports. This development board is compatible with most STM learning tutorials and video projects on
Bilibili. This design uses the STM32F411 as the main controller , the INA226 as the voltage and current detection module , the W25Q128JVSIQ memory chip, and a 4-inch IPS LCD display. The source code is entirely open source for easy learning. The host computer can be downloaded from the official website using VOFA+. ​​Expansion I/O ports are provided using a pin-type design for easy expansion. The required functions and definitions are explained in the hardware description. Required nylon posts include: 6 M39 posts , 2 M39+6 posts, and 4 M35+6 posts. Nylon straight-through posts are also included. (Dimensions: 3.25 x 2.5 mm ) 4 M35 screws, 8 LCD screens , 4-inch IPS full-view screen from Yaoyuanhong Technology on Taobao, no touch screen: https://item.taobao.com/item.htm?_u=788del24c32&id=737966874686&spm=a1z09.2.0.0.724b2e8dnr4ZhW&skuId=5267043615195 . Main controller is STM32F411CEU6, please purchase separately. TYPE-C interface, 16-pin, vertical plug, black, standard model, 10.5h. The software ( link: https://item.taobao.com/item.htm?_u=788del24713&id=753926992827&skuId=5201266957788&spm=a1z09.2.0.0.724b2e8dnr4ZhW ) currently has some bugs and is still being optimized and adjusted. New versions will not be available in the future.
