Ornament and Crime O_C

Update via USB using Teensy Loader application (v1.33 or later). Requires that the USB trace on the module's Teensy microcontroller has been cut (a one-time hardware preparation step). Connect a micro-USB data cable from the Teensy to a computer. Download the HEX file from the GitHub releases page. Open in Teensy Loader, press the program button on the Teensy board, then click Program. Calibration data is preserved across firmware updates and no recalibration is needed.
