32-channel steering robot driver board based on ESP32

Overview

For the needs of making robots, we designed this 32-channel servo drive board. The board can drive PWM servos from 5 to 12V. It can adapt to a wide voltage range, so it is very convenient to use.
There is a voltage monitoring circuit and buzzer on the board, so if you use a battery to power the robot, you can measure the battery power through the voltage detection circuit. If the power is too low, you need to alarm and stop the robot to prompt us to charge.
There is also an mpu6050 onboard, so that we can perceive the robot's posture and other information, and plan actions based on the robot's posture.
At the same time, there is a small 1.14-inch color screen onboard with a resolution of 140*240, which can display the status of the board and robot in real time to facilitate on-site testing of the robot.
There are also several independent buttons on the board. As debugging buttons, the button functions can be flexibly customized to debug the robot.

The LM3S chip is very popular in the forum, but it is found that not many people actually use it, and it does not seem to have any price advantage.
