SparkFun Electronics® Releases SparkFun Edge—the Ultra-Low Power Development Board for Machine Learning using TensorFlow Lite

Developers can join SparkFun Founder Nathan Seidle and Google Engineer Pete Warden for a livestream and Q&A at 11am Mountain on April 5, 2019

Boulder, CO, April 01, 2019 (GLOBE NEWSWIRE) -- The SparkFun Edge, a new development board powered by Apollo3 from Ambiq, is now shipping from The SparkFun Edge was created in collaboration with Google’s TensorFlow Lite team to create new tools for developers to bring voice and gesture recognition to edge devices. The Apollo3 from Ambiq uses a Cortex M4 processor with 384KB of RAM and 1MB of Flash storage, requiring extremely low levels of power and allowing the SparkFun Edge to run for several days on a coin cell battery. SparkFun Founder, Nathan Seidle, and Google Engineer, Pete Warden, will be hosting livestream at 11am Mountain Time on Friday, April 5, 2019 ( for developers to ask questions and learn the story behind the SparkFun Edge.

“Academia has been talking about artificial intelligence for decades, and while the field has made amazing strides, there haven’t been many tangible effects for general users. With exciting new tools like TensorFlow for machine learning, and increasing processing power, we are starting to see improvements that we can begin to reap benefits from,” said Seidle.

"We wanted to show examples of TensorFlow running on embedded systems at a super-low power—we needed a tool to do that. We talked with SparkFun and Ambiq and now we are able to share this device with the world,” said Pete Warden.

The utilization of Ambiq Micro's latest Apollo3 Blue microcontroller, an ultra efficient ARM Cortex-M4F 48MHz (with 96MHz burst mode) processor, runs TensorFlow Lite using only 6uA/MHz. Apollo3 Blue sports all the cutting edge features expected of modern microcontrollers including six configurable I2C/SPI masters, two UARTs, one I2C/SPI slave, a 15-channel 14-bit ADC, and a dedicated Bluetooth processor that supports BLE5. On top of all that the Apollo3 Blue has 1MB of flash and 384KB of SRAM memory - plenty for the vast majority of applications.

On the SparkFun Edge, developers will have built-in access to sensors, Bluetooth, I2C expansion, and GPIO inputs/outputs. To support edge computing cases like voice recognition the Edge board features two MEMS microphones, an ST LIS2DH12 3-axis accelerometer on its own I2C bus, and a connector to interface to an OV7670 camera (sold separately). An onboard Bluetooth antenna gives the Edge out-of-the-box connectivity. Also available on the board is a Qwiic® connector to add I2C sensors/devices, four LEDs, and four GPIO pins. To boast its low-power capabilities, the board is outfitted with battery operation from the CR2032 coin cell holder. Programming the board is taken care of with an external USB-serial adapter like the Serial Basic Breakout via a serial bootloader, but for more advanced users the board also includes JTAG programming and a debugger port.

As an entirely open-source project, developers can take a look at the code and hardware files on GitHub and at

About SparkFun Electronics (

In 2003, CU student Nate Seidle blew a power supply in his dorm room and, in lieu of a way to order easy replacements, decided to start his own. Since then, SparkFun has been committed to sustainably helping our world achieve electronics literacy and explore the edges of technology from our headquarters in Boulder, Colorado. No matter your vision, SparkFun's products and resources are designed to make the world of electronics more accessible. In addition to more than 2,000 open source components and widgets, SparkFun offers online tutorials and training designed to help demystify the wonderful world of embedded electronics. We're here to help you start something!

About TensorFlow (

TensorFlow is Google's end-to-end open source machine learning platform. In the three years since launch, TensorFlow has matured into an entire end-to-end machine learning (ML) ecosystem helping to power the ML revolution we see happening around us. It has been downloaded over 41 million times and has over 1,800 contributors from around the world. TensorFlow as a comprehensive ML platform is helping a diverse set of practitioners, researchers, and new users to build amazing new solutions to solve challenging problems with AI.
