Summary of REDBOARD ARTEMIS – SPARKFUN’S NEW BLUETOOTH ENABLED ARTEMIS MODULE
The SparkFun RedBoard Artemis (DEV-15444) is a low-power microcontroller board with an Arduino Uno R3 footprint. It features the Ambiq Apollo3 processor, running at 48MHz up to 96MHz, and includes Bluetooth 5.0, a digital MEMS microphone, USB-C, and Qwiic connectors. Compatible with the Arduino IDE, it offers extensive I/O capabilities including multiple UARTs, SPI, and I2C buses, making it ideal for voice commands and machine learning applications using TensorFlow Lite.
Parts used in the RedBoard Artemis:
- Ambiq Apollo3 Cortex M4F Processor
- USB-C Connector
- Qwiic Connector
- Digital MEMS Microphone
- Built-in BLE 5.0 Module
- Current Consumption Jumpers
SparkFun‘s new DEV-15444 RedBoard Artemis has an Arduino Uno R3 footprint, 1M Flash/384 KB RAM, and a processor that uses less than 1mA of current at peak. This Artemis board includes a modern USB-C connector and a Qwiic connector that makes programming and I2C easy. This RedBoard is fully compatible with SparkFun’s Arduino core and can be easily programmed with the familiar Arduino IDE. It also has a digital MEMS microphone which is definitely going to help with always-on voice commands and machine learning with TensorFlow lite. The DEV-15444 RedBoard runs at 48MHz (turbo up to 96MHz) and Bluetooth to boot. This Artemis board also features 2 UARTs, 6 I2C buses, and 4 SPI buses. There is also added support for jumpers to measure current consumption for low power testing.
