Introduction

Our Artemis line would not be complete without including the Feather-compatible SparkFun Artemis Thing Plus. With 21 GPIO Pins - all PWM and interrupt capable - there are 2 I2C buses available, as well as SPI and UART. We've included the digital MEMS microphone that allows for always-on voice commands with TensorFlow and machine learning, and the Qwiic connector makes using our Qwiic sensors as easy as plug and play!

Required Materials

You'll need the Artemis Thing Plus and a USB C cable. Any USB C cable should work, including the one that probably came with your phone charger.

  • Built in BLE radio
  • 8 ADC channels with 14-bit precision
  • 2 I2C buses
  • 1 SPI bus
  • 2 UARTs
  • PDM Digital Microphone
  • I2S Interface
  • Qwiic Connector

Serial and JTAG Programming

The RedBoard Artemis Thing Plus has two methods for programming. The most common is the USB C connector that operates as a USB to serial bridge. By simply pressing 'Upload' in the Arduino IDE or 'make bootload' from the SDK the firmware on Artemis is updated.

We use the CH340E on the RedBoard Artemis Thing Plus. The driver should automatically install on most operating systems. However, there is a wide range of operating systems out there. You may need to install drivers the first time you connect the chip to your computer's USB port or when there are operating system updates. For more information, check out our How to Install CH340 Drivers Tutorial.

The second method is JTAG programming. An unpopulated JTAG footprint is available for more advanced users who need breakpoint level debugging. We recommend checking out our JTAG section for the compatible male header and a compatible JTAG programmer and debugger.

GPIO

The Artemis Thing Plus has 21 available GPIO pins on either side of the board. In addition, there are separate IO for a user button and LED. The LED pin supports PWM but the button's pin does not. The Artemis Thing Plus Schematic can give you more information on which of the Apollo3 pads are broken out for the Thing Plus. You can also cross reference this with the Apollo3 Pad Map.

Qwiic and I2C

The I2C pins on the Artemis Thing Plus are labeled SDA and SCL on the back of the board. They are controlled in the Arduino IDE using Wire.begin(), Wire.read(), etc. While pins 16/17 use Wire1, the Qwiic connector uses Wire so you can use SparkFun's Qwiic ecosystem (there's over 50 boards and more every week!).

Mic and RTC

The Artemis excels at low power voice recognition. To enable this we've included a PDM MEMS microphone on the board. Additionally, the Artemis module can operate an RTC given an external 32kHz crystal so we've included that was well.

Board Dimensions

All board dimensions are listed in inches. Overall the pcb measures 2.3x.9 inches with a slight overhang from the USB-C connector.
