Highly-expressive, transparent, open-source sip-and-puff interface based on ATMega32u4 and MX12GP.
- Based on ATMega32u4 loaded with the Arduino Leonardo bootloader.
- Uses a USB mini-B connector for all data and power.
- Uses the MX12GP pressure transducer connected through an AD8223 instrumentation amplifier to an analog input of the ATMega32u4.
