2 Board Resources
Here aims to introduce the hardware and software resources of the M48Z-M33 Mini Board, including the introduction of chip resources, the introduction of experimental platform hardware resources, and the supporting resource use guide. By studying this manual, the reader will have a comprehensive understanding of the resources of the Mini Board, which will be very helpful for subsequent program design.
It is intended to provide readers with a comprehensive introduction to the M48Z-M33 Mini Board resources. It is highly recommended that you read this manual before learning the examples!
2.1 Hardware Description
M48Z-M33 Mini Board selects STM32H503CBT6 as MCU, the chip integrates FPU instructions, It has 32KB SRAM, 128KB FLASH, 6 16-bit timers, 1 GPDMA controller (total 8 channels), 3 SPI, 3 full-duplex I2S, 3 U(S)ART, 1 FDCAN, 1 12-bit ADC, 1 RTC (with calendar function) and 37 general IO ports.
- USB interface: this interface can not only be used as a USB slave communication interface, but also has a power supply function, which can supply power for the Mini Board. USB_Slave can be used to connect the computer to realize the USB virtual serial port experiment.
- SWD debug port: used for simulation debugging, downloading code, etc.;
- Reset button: used to reset the Mini Board.
2.2 Software Resources
There are up to 35 examples provided. Before learning each example, carefully read the README.md, which includes a brief introduction to the example function, hardware hookup, STM32CubeIDE configuration instructions, and running phenomena. Here are all the examples.
