Editor’s take

In favor

  • Fully open-source hardware + firmware + SDK
  • 16 channels — best price/coverage in the open ecosystem
  • Strong BrainFlow / LSL / MNE integration

Against

  • Effective sampling drops to 125 Hz with Daisy
  • Requires self-assembly
  • Bluetooth pairing finicky in dense RF
