The carrier board provides three PMOD connectors, two ADC interfaces, an SD card slot and an EEPROM for additional storage. There is also a M.2 slot on the bottom of the device, but the Wiki pages indicate that it’s “reserved” so users might have to write the drivers themselves.

    You need to check the specs, you said it has 13k LUTs and registers. It actually has 138k LUTs, which is a big difference.

  2. Giorgio Mendoza says:

    I apologize, it was a typo.
