Adafruit has announced the availability of the AirLift Bitsy add-on ESP32 WiFi co-processor priced at $14.95. This innovative daughterboard allows you to use the powerful ESP32 as a WiFi co-processor, significantly enhancing the capabilities of your projects. By offloading the WiFi connection management to a separate chip, your code becomes simpler and more efficient. This setup eliminates the need to cache socket data or compile and debug an SSL library, making your development process smoother and more streamlined. Adafruit provides further insights into the new arrival:
Enhanced Functionality with ESP32
“You probably have your favourite ItsyBitsy (like the Itsy’ M4) that comes with its own set of awesome peripherals and lots of libraries. But it doesn’t have WiFi built in! So let’s give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi network and transferring data from a site, even if it’s using the latest TLS/SSL encryption (it has root certificates pre-burned in). Send basic but powerful socket-based commands over 8MHz SPI for high-speed data transfer.”
The ESP32 is a robust and versatile chip that can manage complex tasks such as connecting to WiFi networks and handling data transfers securely. With root certificates pre-burned in, it ensures secure connections using the latest TLS/SSL encryption standards. This makes it an ideal companion for your ItsyBitsy projects, providing a seamless and secure WiFi experience.
Applications and Benefits
The AirLift Bitsy add-on ESP32 WiFi co-processor is perfect for a wide range of applications. Whether you’re working on IoT projects, home automation, or data logging, this co-processor can handle the WiFi connectivity, allowing your main microcontroller to focus on other tasks. This division of labor not only simplifies your code but also enhances the overall performance of your project.
For instance, in an IoT project where multiple sensors are collecting data, the ESP32 can manage the WiFi communication, sending data to a cloud server or a local database. This ensures that your main microcontroller is not bogged down with network-related tasks, allowing it to process sensor data more efficiently.
Moreover, the high-speed 8MHz SPI interface ensures rapid data transfer between the ESP32 and your main microcontroller. This is particularly beneficial in applications where real-time data processing is crucial, such as in robotics or live data monitoring systems.
