Overview

Function description: You can use wifi connection to remotely control writing, drawing graphics, writing time and other operations

Design plan: 1. Hi3861 core board + PCA9685 servo driver board + Type-C power supply

2. In order to reduce the difficulty of welding, the capacitors and resistors are packaged in 0805. The servo driver board uses finished modules. TypeC uses finished direct plug sockets. The servo driver board and the servo driver board are reserved in the core board.

Type-C female direct plug interface

Product parameters: Working voltage: 5V+3.3V, maximum working current: 3A

Hardware interface: GPIO, ADC, PWM, and I2C are all individually derived

PCB design: using Jialichuang EDA professional version, double-layer board + single-sided layout

List of materials: MG90S servo (180°)*3, the main body is cut from 3mm acrylic, the pen holder and blackboard eraser are 3D printed

Instructions for use: 1. Use HiBurn for burning. For the burning method, see the attachment - Hiburn burning instructions.

2. For the IO ports connected to the three servos, please see the attachment - Xiaojian Zhong Servo IO Connection Comparison Diagram

3. After the computer is connected to the wifi of the board, enter 192.168.10.1/plot in the browser to enter the webpage to install, debug and send the clock.

(1) Click the installation angle, and the left and right servos will turn to the installation angle. At this time, the two swing arms are fixed and installed vertically. The installation angle of the lower servo is 45°, and the servo rotation with port 15 needs to be controlled on the web page.

to 45°. At this time, the fixed swing arm is installed horizontally with the ground.

(2) You can use the DogLeg software in the attachment to customize the trajectory of the clock.
