Elecfreaks EF08288 NEZHA Inventor's Kit V2 for micro:bit (without micro:bit) content_copy

The ELECFREAKS NEZHA Inventor’s Kit V2 for micro:bit is a learning and experimentation kit developed based on Planet-X sensors. It serves as a programming learning set for children and teenagers to playfully learn fundamental concepts of electronics, robotics, and programming. The kit is specifically designed for use with the BBC micro:bit V2, although the micro:bit board itself is not included in the package. It offers a wide range of sensors and modules suitable for various applications in robotics and STEM education.

Applications
This kit is ideal for use in schools, workshops, maker spaces, or at home to introduce children and teenagers to the world of programming and electronics. It promotes practical skills, logical thinking, and creative problem-solving. The 32 thematic case studies and extensions provide structured instructions for implementing various projects such as robots, lighting systems, or sensor networks. The modules are also designed to serve as a foundation for individual developments for advanced users.

Features and Equipment in Detail
The kit includes a variety of sensors and modules, such as LED lights, potentiometers, soil moisture sensors, ultrasonic sensors, collision sensors, and line-following sensors. These enable the collection of various environmental data, such as distance, moisture, light, or physical contact. The sensors can be controlled via 7 RJ11 interfaces on the Nezha board, allowing for flexible combinations and expansion of functions. Additionally, the board features 4 TT-motor interfaces, 4 servo interfaces, and 4 Fischertechnik motor interfaces to control different drive systems.

Technology Explained Simply
The Nezha board is the central control module of the kit. It includes an integrated battery with a capacity of 900 mAh, enabling approximately 2 hours of operation. The nominal operating voltage is 3.7 V, with stable operation between 3.2 V and 4.2 V. The charging voltage is 5 V, and charging via the USB Type-C port takes approximately 120 minutes. The board measures 82 mm in length, 60 mm in width, and 28 mm in height. The integrated power supply via network cable (PoE-like) is not applicable here, as this is a standalone control module with an internal battery.

Compatibility and Accessories
The kit is exclusively compatible with the BBC micro:bit V2. It does not include any additional accessories beyond the mentioned sensors, modules, and building blocks. The more than 400 building blocks allow for the construction of various enclosures and models, enabling individual customization of project designs. The building blocks are not compatible with other systems such as LEGO or Fischertechnik, but are specifically developed for the Nezha kit.

Assembly and Installation
Assembly involves connecting the building blocks and attaching the sensors and motors to the corresponding interfaces on the Nezha board. The interfaces are clearly labeled, and the instructions for the 32 case studies include step-by-step guidance for assembly and programming. Connection to the micro:bit is made via the board’s designated pins, with the micro:bit board needing to be purchased separately.

Advantages in Operation
The kit offers high flexibility due to the wide range of sensors and drive interfaces. The integrated battery function enables mobile applications without external power supply. The clear structure of the case studies and modular design facilitate learning and project repeatability. The use of RJ11 connectors ensures secure and easy wiring of the sensors.
