Exen Mini - Setup 1. If you have not yet downloaded and installed the Arduino IDE to your computer you can download it from the Arduino website here for your OS: https://www.arduino.cc/en/Main/Software It is recommended to download the latest version. In this setup guide we are using version 1.8.1 of the Arduino IDE. 2. Open up the Arduino IDE and navigate to Tools > Board > Boards Manager 3.
. Now that you have the SAMD Boards package installed you should see the newly installed boards in the Arduino IDE boards menu. To check the boards are correctly installed go to your Arduino IDE and navigate to Tools > Board > Boards Manager If you don’t see the boards like in the below screenshot you may need to restart your Arduino IDE. Select the board that says ‘Arduino/Genuino Zero (Native USB Port)’ 5.
6. Once you have a sketch ready you need to upload it to the Exen Mini, this can be done 2 ways using USB. 1) This method is if the Exen Mini is powered only by the USB port A) Plug in the Exen Mini to your computer via USB B) Select the port your Exen Mini is connected to in the Tools > Port menu. C) Press upload to compile and upload your sketch, this first upload will fail since the Exen Mini is in ‘normal’ mode. Once the sketch fails to upload the Exen Mini will put its self into ‘Bootloader’ mode.
