Mosquito-Scope™ (or Squito-Scope™)

I am gathering requirements for the next version of Flea-Scope now, including multiple input amplification ranges (for measuring sub-millivolt signals), 80 Msps using dsPIC33A (or possibly 2 channels at 40 Msps), OPA810 (for 0mV open input offset), BLE, a USB-C connector, GUI support for multiple channels in one web-page, 0.8” PCB width (down from 1.0”), etc.
