Adding Custom Boards to the Arduino v1.6.3+ Board Manager
If you have downloaded v1.6.3 of the Arduino IDE, you may have noticed the addition of a feature called the Board Manager that was added along with the Library Manager. We have been working hard on updating our boards to work with the new manager, but the IDE doesn’t support the adding of third party boards to the list yet. We have a temporary workaround for that issue in the form of a simple open source HTTP proxy that adds our Trinket Pro and Flora boards to the Board Manager list. We have also packaged the ESP8266 Arduino core and the arcore MIDI USB core for the Arduino Micro and Leonardo so they are easy for you to install and use in your projects.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

This is great, except that when I try to compile with my Trinket Pro 5V/16Mhz FTDI, I get
Arduino: 1.6.3 (Mac OS X), Board: "Pro Trinket 5V/16MHz (FTDI)"
Sketch uses 20,740 bytes (72%) of program storage space. Maximum is 28,672 bytes.
Global variables use 313 bytes of dynamic memory.
Error while uploading: missing ‘upload.params.quiet’ configuration parameter
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
Could you try a restart of the Arduino IDE and upload again? If that doesn’t work, could you post your issue to the Arduino section of the Adafruit forums?
