The Artemis Module from SparkFun is the world's first open source hardware RF module enabling both voice recognition and BLE. The core of the Artemis module is the Apollo3 by Ambiq. This is an ARM Cortex-M4F (F indicates hardware floating point operations) with BLE 5.0 that runs at less than 1mA. And it can run TensorFlow models.
You can program the Artemis module easily under the Arduino IDE. With 1M flash and 384k RAM you'll have plenty of room for your code. The Artemis module runs at 48MHz with a 96MHz turbo mode available and with Bluetooth to boot.
Measuring 10x15mm the Artemis module has all the support circuitry you need to use the fantastic Apollo3 processor in your next project. The SparkFun Artemis Module is fully FCC/IC/CE certified and is available in full tape and reel quantities.
This module is for advanced users only. This product is just the module - which is difficult to use. We recommend one of the products mentioned below.
