>The flea-scope's hybrid FPGA/MCU architecture for USB streaming is clever - using FPGA pipelining to handle 100MS/s capture paired with an STM32 for protocol translation is sweet cost-wise. BUT, the 8-bit ADC resolution and lack of input protection networks (compared to Rigol's 1MΩ//20pF frontends with overvoltage clamping) make it risky in case of unattenuated signals.
