Product information "Waveshare RoArm-M2-Pro (EU), 4DOF, 360° rotation, ROS2-compatible, ESP-NOW, Open Source, 12V 5A"
The RoArm-M2-Pro robotic arm series is a modular, intelligent 4-DOF robotic arm system with high-torque servo drives and fully open-source control architecture. The RoArm-M2-Pro model combines a 360° omnidirectional base with three flexible joints and enables a working range with a maximum diameter of 1090 mm. Utilising ST3235 bus servos with metal housings, this design offers improved structural stability and reduced backlash during extended use. The arm is controlled by an ESP32 microcontroller that supports wireless connectivity via WiFi and ESP-NOW. In addition to web app control, the system offers a variety of interfaces for serial and USB communication.
Comprehensive graphical and video tutorials are available. Thanks to its complete openness to sources, it can be easily integrated into customised application projects. The arm is compatible with ROS2, supports JSON-based HTTP commands and offers graphical coordinate control via the web application. The carbon fibre and aluminium alloy structure ensures a low overall weight of 873.3 g (without table mount), allowing the arm to be mounted on different mobile platforms. The system is prepared for various types of installation, such as table clamp mounting, rail mounting and mobile module installations with and without countersinking. The integrated 12-bit magnetic encoder ensures a feedback accuracy of ±4 mm.
The system serves as a multifunctional robotic arm with applications in research, prototyping, automation testing and education. The direct joint control and the inverse kinematics system enable precise positioning through coordinate input. The dual-drive system on the shoulder joint doubles the available drive force. The movements are smooth and stable thanks to curve speed control. The installation of different end effectors (EoAT) is supported by standardised mounting interfaces. Control can be carried out by simply clicking in the browser-based web application. For complex applications, it is possible to customise the control interface and add new functions. The control software is cross-platform and runs on mobile devices, tablets and PCs. In addition, several RoArm-M2 devices can be synchronised via ESP-NOW in leading-following mode.
Comprehensive documentation and tutorials are available. As the hardware and software are completely open source, the RoArm-M2-Pro enables maximum transparency, customisability and interoperability. Developers, educational institutions and researchers can access the entire source code, circuit diagrams and documentation, adapt or extend them as required and thus implement customised solutions and functions. The open-source architecture promotes collaborative further development and also offers long-term investment security as there are no proprietary dependencies.
The RoArm-M2-Pro (EU) product version is supplied pre-assembled and includes mounting materials, brackets and adapter plates for attaching cameras and extension modules. Flash storage on the ESP32 and JSON-based task sequences are available for storing motion sequences. The installation of additional components such as cameras, end effectors or sensors is facilitated by standardised mounting points and supplied accessories.

Waveshare: High quality modules for your Raspberry Pi
Waveshare is a reliable specialist when it comes to displays, cameras and other modules for your Raspberry Pi. With the products of the innovative electronics expert, you can turn your computer into a true all-round device.
Waveshare provides an optimal view
You are looking for the ideal display module for your Raspberry Pi? At Berrybase you will find a wide range of products from Waveshare. Each display and all associated modules have been designed with the utmost precision and meet the highest demands - no matter what purpose the respective product is supposed to serve.
For example, the Waveshare ePaper HATs offer perfect conditions if you want a high display quality even in strong sunlight. A big advantage of ePaper displays is their extremely low energy consumption. The best example is the 2.13" 250×122 ePaper Display HAT with integrated controller, which is optimally tailored to the Raspberry Pi 2B, 3B, Zero and Zero W. The communication with this module is done via SPI interface. The ePaper display equipped with the HAT is limited to the colors black and white and reflects light like conventional paper. This is good for the display quality.
If you prefer a display in the three colors red, black and white to complement your Raspberry Pi, the 2.7" 264×176 ePaper Display HAT is recommended. It has the same technical features as the other Waveshare ePaper HATS.
Compact and of brilliant quality: The Waveshare 7 inch Display
The Waveshare 7 inch display, on the other hand, scores not only with its compact design, but also with a 1024x600 hardware resolution and capacitive touch control. On all devices with Raspberry Pi OS, the 7 inch LCD even works driver-free. The integrated 3.5mm jack enables sound output, while the image is produced via an HDMI connection. The impeccable quality manifests itself in a high-quality glass surface with a 6H hardness level.
At Berrybase, you can get the display including a robust case on request - so that it is optimally protected against external influences. Besides the Waveshare 7 inch display, the electronics specialist also has many other screens in different sizes available.
Waveshare Game HAT: Turning your Raspberry Pi into a game console
One of the top sellers at Berrybase is the Waveshare Game HAT for the Raspberry Pi. The controller transforms your computer into a mobile game console. The 3.5" IPS display convinces with a 480×320 resolution and ensures smooth image playback and thus unlimited gaming fun. The sound is reproduced via on-board speakers or optionally via the 3.5 mm jack socket. The battery of the Game HAT is charged via the integrated charging circuit. The module is compatible with the Raspberry Pi models A+, B+, 2B, 3B and 3B+. For other versions the connection via HDMI cable is possible.
If you want to turn your Raspberry Pi into a mobile retro console, we recommend the GamePi43 with a 4.3-inch IPS display, which is suitable for the Raspberry Pi models B+, 2B, 3B and 3B+, or the especially compact GamePi20. The latter features a 2.0-inch IPS display and is compatible with the Raspberry Pi Zero 1.3, Zero W as well as the Zero WH.
Practical accessories for every purpose
By the way: Waveshare's product range is also peppered with useful accessories for your Raspberry Pi. The Li-Ion battery HAT for example provides a mobile power supply for your computer. The 8 channel DIN rail relay module from Waveshare allows you to use your Raspberry Pi as a control module for tech projects in the home, for example to centrally control the home lighting or shutters. And with the Ethernet / USB HUB HAT, Waveshare has designed a module that extends the USB capability of your Raspberry Pi and provides an RJ45 Ethernet port. The latter offers an enormous added value when a stable wired Ethernet connection is required.
