README
KiCad/dAISy BoosterPack/readme.mdBreakout board for the Si446x as MSP430 BoosterPack.

Paired with a TI MSP430F5529 LaunchPad, this board can also be used with the (closed source) dAISy USB firmware.
This breakout board is also the basis of this project, which uses the Raw or Sync data from the Si446x for audio input into ShipPlotter software.
