Depends on the protocol they use on the USB connection. Serial over USB has its quirks. Using a Leonardo, a Due or a SAMD21 based Arduino allows you to implement something like HID which should give you better latency
- madeintheusb 10y agoYou are right though I do think HID is limited to 64 Kbytes/S. But an SAMD21 or 32U4 could allow me to build a cheaper product. I have to think about it now. What I am currently achieving is - 100Kbytes/S in I2C with a 10Mhz I2C EEPROM and - 2.4 Mbytes/S in SPI with a NOR FLASH at 103Mhz using the FTDI FT4222 and the FT232H should the same or better.
