F7ZkZv

Gongchuang (no expansion port)

Overview

An expansion board designed based on the STM32F407VET6 core board. The power supply part: uses two voltage stabilizing modules to convert to 9v and 5v respectively, ams1117-3.3v, has a power indicator light and a voltage measurement circuit. Drive part: One a4988 module controls the stepper motor, and two tb6612 control 3 DC motors (the black plastic of the pin header must be removed so that it will not hit the 32 board above, the design is very extreme). Other modules: buzzer, buttons.
