I. Overview

This vehicle is a new energy disinfection vehicle, specially designed for "unmanned" household disinfection. It has low cost, compact appearance, and strong scalability. It can be transformed into an emergency power supply vehicle, an "unmanned" plant sprinkler vehicle, and a wedding vehicle. Rings, necklaces, teleporters, etc.

The new energy disinfection vehicle adopts a modular design and different modules can be replaced as needed. The disinfection vehicle is equipped with an ESP32CAM camera module, a large-capacity lithium battery module, a 4-way L9110 motor drive module and a spray module (humidifier)

2. ESP32CAM

The ESP32CAM camera module is a customized module. It is different from the official ESP32CAM module of Essence in terms of function and size. The main difference is that the customized ESP32CAM camera module has an onboard Type-C interface and CH340 circuit. The program can be downloaded with one click through the type-C interface. , without psram (cache) chip, the measured video stream output has no impact, leads to 8 gpio for use (excluding LED flash control pin), board size 55x30mm,

3. Lithium battery module

This module adopts 2 parallel and 2 series design. There is a 10A 7.4V 8.4V balanced 2-string lithium battery protection board on the bottom of the board. DC-DC stamp hole step-down power supply 5V*2, 3.3V*1, which can provide peripheral equipment The efficient and stable power supply leads to the XH2.54 interface, 5.0-section front terminal, DC-012 interface, USB interface and pin header to facilitate the access of electrical equipment.

4. Motor drive

The motor driver adopts L9110 motor driver. The motor driver GPIO pull-up resistor is 10K. The motor driver is divided into 2 outputs, which can be used perfectly with the customized ESP32CAM development board.
