Proffieboard V3.9 - Open Source Lightsaber Sound Board

The Proffieboard is a revolution in lightsaber electronics. Fully open source this feature packed board includes smooth swing which provides the most realistic sound effects we have seen in a sound board. The v3.9 ProffieBoard is the latest update in the Proffieboard saga and features a more powerful STM32 microprocessor combined with a motion coprocessor IMU, 3W audio amplifier, and 6 MOSFETs to control external LEDs. It features USB charging, support for deep sleep, additional flash memory (512kb), and much more.  New in V3.9: More FLASH (512kB instead of 256kB): This means more presets, but it also means we can now turn on optimization without running of of memory More RAM (160kB instead of 64kB): No immediate effect, but makes mp3 and echo effects possible More PINS: New CPU is BGA with 64 pins instead of 48. This means more data pins, and and other things, listed below Faster SD card access. The new board uses SDIO instead of SPI to access the SD card. SDIO is significantly faste
