Conexio BLITZ is a versatile all-in-one IoT prototyping companion designed for enthusiasts, by enthusiasts. It has been engineered to suit a wide range of IoT applications, including smart home automation, health and wellness monitoring, industrial IoT, inventory management in retail, and so much more.

Thanks to its powerful SoC and plentiful I/O, even demanding edge computing use cases like anomaly detection in industrial equipment are possible with BLITZ. Developers and hobbyists alike can connect their existing projects to the cloud or other local endpoints without worrying about infrastructure costs.

Supports Most Popular Wireless Protocols

BLITZ supports an extensive range of wireless protocols. It supports Bluetooth Low Energy 5.4 standard and can Bluetooth Direction Finding. In addition, it supports LE Audio, a high-throughput 2 Mbps data transfer, advertising extensions, and long-range mode. Run protocols like Bluetooth Mesh, Thread, and Zigbee concurrently with Bluetooth LE for provisioning, commissioning, or configuring mesh networks. Unlock the potential of sub-1 GHz with BLITZ, as it also supports 802.15.4 and 2.4 GHz proprietary protocols.

In the digital age, WiFi is a powerful tool. And let’s be honest, who wouldn’t want onboard WiFi? With Nordic Semiconductor’s latest nRF7200 WiFi chipset, BLITZ delivers high-speed, reliable wireless internet connectivity and seamless local device communication, ensuring your IoT projects and products are at the forefront of technological advancements.

Convenient Feather Form Factor

Designed to be adaptable, BLITZ also embraces modularity. Its QWIIC connector and feather-compatible 28 header pins are ready to integrate with compatible modules, allowing you to extend its functionality with additional hardware like cameras, thermometers, or ultrasonic distance sensors. This extensibility makes BLITZ a foundation for innovative hardware interfacing.

In addition, Conexio BLITZ is equipped with a USB Type-C port, enhancing its connectivity options. This port allows for easy connection with a wide range of devices and accessories, battery charging, debugging, and programming.

Visual Studio Code Plugin Support

To make application and project development with Conexio BLITZ fun and fast for low-level application designers and novices alike, we made BLITZ compatible with nRF Connect for Visual Studio Code. Using the nRF Connect plugin, you can build, compile, and deploy codes to Conexio BLITZ with minimal effort. Create projects with nRF Connect SDK and Zephyr RTOS with built-in templates created by the Conexio team. All the firmware examples and the source files will be available for download when the campaign is completed.

Open Source

For those of us who love tech, the ability to tweak and personalize IoT hardware is vital. Open-source firmware empowers users to customize and enhance their devices while fostering a collaborative community that contributes to continuous innovation and improvement. We’re excited to see what users do with BLITZ, be it introducing Home Assistant compatibility or integrating the board into other devices.

This approach makes Conexio BLITZ adaptable to individual needs and ensures transparency and a shared platform for development. So, when we’re ready to deliver boards to backers, we will make our GitHub repository public.
