Waveshare Wave Rover Flexible and Expandable 4WD Mobile Robot Chassis, Full Metal Body, Multiple Hosts Support, with Onboard ESP32 Module

Equipped with N20 reduction motors that use high-quality gearboxes, enabling it to travel at a high speed of 1.25m/s. The flexible rubber tires significantly reduce the impact of complex terrains on the product. It features a 0.91-inch OLED screen for interactive purposes. The product is designed with a charging interface and automatic download circuit, allowing it to be used while charging

The UPS power module on board contains an INA219 acquisition chip, facilitating real-time monitoring of batt voltage and charging current. The UPS power module utilizes three series-connected batt with a large capacity of 7800mAh, providing a higher output current and stronger motor power. It also offers 5V and 3.3V outputs for expanding other devices

The module includes a batt protection circuit, offering functions such as overcharging, over-discharging, overcurrent, and short-circuit protection. The sample code is developed using Arduino IDE, eliminating the need for manual configuration of the compilation environment. The open-source resource includes planar drawings and chassis structural drawings, including 3D models, facilitating secondary development

Upon startup, the ESP32 automatically establishes a WIFI hotspot. Users can connect and log in to the control interface using a smartphone (Android/iOS) or a computer (Linux/Windows/Mac) with any Chromium-based browser, without requiring an app download. The entire code is open-source and comes with online rich development documentation and tutorials

The slave ESP32 can be used to drive DC motors and serial bus servos and supports interfaces for OLED screens, TF card slots, a nine-axis IMU module, WiFi, and BT. Even without installing an upper-level device, it can be used independently.The system can be extended with various host devices, using serial communication to transmit control data in JSON format
