Future growth... AHRS and more channels

After I've completed the basic version, which is using a very small ATMega328 based processor, I'd like to expand.

The next gen processor would be the Teensy LC ($11.65).  Why this?

• Built in Hardware Serial (hardware I/O buffering)
• Much more powerful 32-bit RISC processor
• More Flash (64kb) and RAM (8kb) to do bigger/faster real-time calculations
• More and better I/O, 13 12-bit Analog inputs

This enables;

• AHRS / EIS output to a smart phone or tablet via USB.  Smart phone MFD/PFD for $60
• More analog inputs.  Multiple CHT, EGT, Manifold Pressure, etc
