ROS Ackerman Simplification
This is a simplified control board for the lower-level machine of an Ackerman ROS robot. It's a beginner's drawing board and not very mature.
Includes an STM32C8T6 minimum system board, motor drive module, MPU6050/6500, MINI560 step-down module, DRV8833 motor driver, and a reserved Bluetooth interface. It can implement basic functions as a lower-level controller for ROS vehicles. Because it only provides two motor interfaces, one motor module, and one PWM interface for controlling the servo motor, it can be used as a control board for Ackerman vehicles. It can also be modified to control two-wheel differential vehicles and other types of vehicles as needed.

LM5122 Boost Module 12V to 24V 5A Dual Phase - [Refer to Official Layout]
LM5122 12V to 24V dual-phase module
This is a 12V to 24V module based on the LM5122QMHX boost converter chip, with layout and parameters automatically generated by TI tools.
Theoretically, it can output 10A of high current with a 240W load, but the actual output depends on the components used; without a load tester, the exact figures are unclear.
The inductor used is a domestic PQ2615, 10uH 30A.
An extended dual-phase interface is provided, with wiring instructions printed on the board. For extended use, the input and output need to be connected in parallel.
The extended dual-phase interface works normally in actual testing; however, its effectiveness is unknown. Further verification with an oscilloscope is needed; proceed with caution when prototyping.

STM32F407VET6 Minimum Development Board 2.0
The STM32F407VET6 minimum system development board 2.0 has been successfully prototyped and tested, but has not yet been soldered. Optimization is currently at this stage. Discussion and guidance are welcome. (Only group: 289917684)
The STM32F407VET6 minimum system development board 2.0 has been successfully prototyped and tested, but has not yet been soldered. In previous versions, the 1.27mm header pins were found to be too expensive, so a baseboard was added to solder the core board onto it. The solder pads on the baseboard will be lengthened later for easier soldering. This is the current optimization. Discussion and guidance are welcome. (Only group: 289917684)
