Using STM32F072 to regulate the pocket experimental power supply of TX4211 and SY6345

Cruelfox, a forum expert, has updated his article to share with you an experimental idea of ​​a CNC experimental power supply. The power supply uses two domestic chips, with a 3,000-word detailed explanation. He briefly talked about the first experimental power supply he made, whose shell was an aluminum medicine box and whose knob was a toothpaste cap. He mainly talked about the ideas and principles of the current mini PCB pocket version.

Design of car system based on STM32 Bluetooth control (hardware + source code + paper)

 "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.
