SparkFun Qwiic Pro Micro BoogieBoard

This SparkFun Qwiic Pro Micro BoogieBoard was a limited edition version of the Qwiic Pro Micro. We are now out of stock and are not reproducing it.

The SparkFun Qwiic Pro Micro BoogieBoard is a Special Edition version of the SparkFun Qwiic Pro Micro with new silk on the underside of the board. The board is the same size as the original Pro Micro but we added a few additional features by shrinking down some components on the board such as a reset button, Qwiic connector, USB-C, and castellated pads (this makes it really handy for you custom keyboard creators out there)! Think the Pro Mini except with an ATmega32U4 on board and full USB functionality.

This tiny little board does all of the neat-o Arduino tricks that you're familiar with: nine channels of 10-bit ADC, five PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 5V and 16MHz, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere. There is a voltage regulator on board so it can accept voltage up to 6VDC. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC.

The benefit of the reset button is to quickly reset the board or place it into bootloader mode without the need to take out a piece of jumper wire. The USB micro-b connector has been replaced with the USB type C connector. The through-hole pads have castellated edges for each pin to add a lower profile in your projects should you decide to build it into another assembly during production. Finally, a Qwiic connector is populated on the bottom of the board to easily add Qwiic enabled I2C devices to your projects!

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

    I followed the "Qwiic Pro Micro USB-C (ATmega32U4) Hookup Guide" and encountered several issues trying to get a Hello World program to work (clean Arduino install on Windows 10 and Fedora 32, all add-ons update, "Sparkfun SAMD (...) Boards->Sparkfun Qwiic Micro" board type selected). Here are a few tips for others intending to do the same:

    1) TXLED0 and TXLED1 macros were not recognized by the compiler. Rather than trying to resolve this, I just commented these lines out since they weren't critical for Hello World program.

    2) Serial1 (hardware serial) was similarly not recognized by the compiler. Likewise commented it out.

    3) Could not upload the compiled sketch. The Arduino/bossac software seemed to be initiating the bootloader reset via 1200 baud, but the timing was off and it was terminating on not being able to find the serial port. After 2 days of troubleshooting (double-tapping the reset button in sync with initiating the upload, manually setting the baud rate to 1200, etc), on a whim I changed the board type to "Arduino AVR Boards->Arduino Micro" and the upload worked flawlessly on board Windows and Linux. This also resolved the missing TXLED0/1 and Serial1 compilation errors above.

    Can the micro be run at 3.3 V by changing JP4?

    • Shane Pelletier / about 4 years ago / 1

      I'm going to answer two questions for the price of one here since I'm not 100% sure what question you're actually asking. Hopefully one of my answers is the right one for your question :).

      From the hookup guide, schematic, and datasheet from the voltage regulator, it looks like the Qwiic Pro Micro board can be powered by 2.5V-6V. JP4 controls the voltage the microcontroller itself runs at, which in turn affects the voltages output by the IO pins. So, if you just want to power the board with 3.3V, you can do that without touching JP4. If you want to use the board with components that require 3.3V, you'd change JP4 to select the 3.3V setting.
