Review: Vive l esp32 - Pour qui cherche une base de travail autour d ESP32, voici un excellent produit réellement open source. Beaucoup de possibilités d add on autour de la carte robot. Pour le prix, lets go.. Review: Good but not can be improved - The solid metal body is impressive. One of the wheels is a bit loose though. In general it’s good for this price. ## Features - 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CF55LM6Q | | Additional Features | On-board mounted ESP32 module | | Age Range Description | 14+ years | | Are Batteries Required | No | | Batteries are Included | No | | Battery Description | 18650 Li, 7800mAh | | Best Sellers Rank | #81,780 in Computers ( See Top 100 in Computers ) #1,244 in Single-Board Computers | | Brand Name | Waveshare | | Color | black | | Customer Package Type | FFP | | Customer Reviews | 3.5 out of 5 stars 55 Reviews | | Educational Objective | Learning Robotics, Programming, and Electronics | | Included Components | 3S UPS power supply module, multi-functional robot driver board based on ESP32, 0.91inch OLED screen | | Is Assembly Required | Yes | | Item Weight | 2.6 Pounds | | Manufacturer | Waveshare | | Manufacturer Part Number | WAVE ROVER (EN) | | Manufacturer recommended age | 0 - 1 years | | Material Type | Metal | | Maximum Speed | 4.5 Kilometers per Hour | | Model Name | WAVE ROVER (EN) | | Model Number | WAVE ROVER (EN) | | Number of Items | 1 | | Number of Packs | 1 | | Operation Mode | Remote Control | | Power Source | Battery Powered | | Set Name | 1 | | Size | 33.7 millimeters | | Sub Brand | Waveshare | | Subject Character | Action figure | | Theme | Video Game | | Toy Vehicle Form | Crawler | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Waveshare - **Model name:** WAVE ROVER (EN) - **Connectivity technology:** Bluetooth - **Included components:** 3S UPS power supply module, multi-functional robot driver board based on ESP32, 0.91inch OLED screen - **Operating system:** Linux, Windows 10 ## Images ![Wave Rover Flexible and Expandable 4WD Mobile Robot Chassis, Full Metal Body, Multiple Hosts Support, with Onboard ESP32 Module - Image 1](https://m.media-amazon.com/images/I/61ANtWcK24L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Vive l esp32 *by P***R on 24 November 2023* Pour qui cherche une base de travail autour d ESP32, voici un excellent produit réellement open source.
