Project description

The Arktika FPGA is an open-source FPGA development board based on the ICE40 family (ICE40HX4K-TQ144).

Main Features:

• 78 total user digital IO pins
  • 18 arduino uno compatible headers
  • 6 PMOD connectors (40 total pins)
    • 2x10pin
    • 2x6pin
    • 2x4pin
  • 18pin additional "EXT" connector
  • Buzzer connector
• 4 analog input channels
  • MCP3204 ADC
• 8 on-board LEDs
• 8 on-board DIP switches
• 4 on-board push buttons
• USB to UART bridge
• 50Mhz active crystal oscillator
• FT232hl USB bridge
  • Used for FPGA or flash programming
  • Breakout header for external use

Known bugs

• V1.0
  • Flash CS line not connected (typo on net name)
  • Arduino connector mirrores (inteded for a shield and not the arduino footprint)
  • Wrong usb to uart bridge footprint (the footprint is correct, but it is not for the intended version of the IC)

Development Log

• 27/09/20 (up to)
  • Finishing PCB design
  • Tested toolchain with some examples
