"Bluetooth controlled car based on stm32f4" is a motor drive module, power management module, stm32f4 main control module, Bluetooth serial communication module, and android control module based on the STM32F4 DISCOVERY development board produced by STMicroelectronics and ARM. The motor drive module uses two L298N chips to drive 4 motors. The enable terminal is connected to 4 PWM wave signals from the main control board, and the 8 input terminals are connected to the 8 output ports of the main control board; the power management module uses LM2940 -5.0 chip converts 12V to 5V, 12V is used for power supply of motor modules, and 5V is used for power supply of Bluetooth modules, sensors, etc.; the main control module uses the MDK editing program and then downloads it to the main control board to realize the integration of hardware and software Interaction; the Bluetooth serial port communication module uses the FBT06_LPDB pin-in Bluetooth module to communicate with the main control board through the serial port and at the same time communicate with the android phone; the android control module is a set of functions such as turning on Bluetooth, searching for Bluetooth, and controlling the car. Users can control the movement of the car through the android control terminal to achieve some functions and services that users need.

Supports various Cortex-M cores, can be used wirelessly in the local area network, and can be used remotely in the external network.
The Jlink OB made by F072 has a maximum speed of 3000kHz, and the Jlink V9 has a maximum speed of 12000kHz.
AT89C52 microcontroller is used as the core control component to design an electronic keyboard. The microcontroller is used as the main control core, and it forms the core main control module together with the keyboard speaker and other modules. The main control module is equipped with 8 buttons and a reset button.
A hardware control circuit with TMS320F28335 as the core was designed, and experiments were conducted on the AC speed regulation SVPWM algorithm.
The STM32 Nucleo-64 board provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and power consumption features, provided by the STM32 microcontroller.
This little robot is called ONE, which is actually a work UP made when he was in school five years ago. After finishing it that year, I never had time to sort out the materials. During this period, many classmates came to ask me questions related to this project. This time, I simply uploaded the materials to Github and made them open source. Open source information includes the source code of the STM32 main control and the 3D model files of the mechanical structure. The circuit source files can no longer be found due to their age. Students with basic knowledge can study it by themselves~
The product design is open source and very cool and beautiful.
