• RP2350 Microcontroller
  • I/O bus connection to the FPGA.
• GOWIN GW1NR-9 FPGA.
  • 8MB internal PSRAM.
  • Internal bitstream Flash with AUTO BOOT.
• Non-volatile memory.
  • 4 MB User Flash.
• Peripherals
  • RP2350
    • 8 x GPIO.
    • 4 x ADC.
    • 1 x LED.
  • FPGA
    • 16 x GPIO.
    • 1 x LED.
    • 2 x Pushbuttons.
• USB-C connector
  • UART over USB (Thonny)
  • JTAG over USB
• 1 x Power LED.
• 3.3V and 5V rails.
• EPM11-MCU example project (coming soon!).
  • Custom, board-specific MicroPython image.
  • Includes a scripting layer for ‘out of the box’ communication with the FPGA.
  • Includes a custom Pin and ADC mapping.
• EPM11-FPGA example project.
  • Includes a guided setup of the FPGA build prerequisites and environment.
  • Includes a CPU interface module (coming soon!).
  • Provides an example of building and probing an fpgacapZero Embedded Logic Analyzer (ELA).
  • Extensible, i.e. user can add their own application specific RTL modules.
  • Simple build and program workflow stages.
  • Fully scripted workflow – no GUI-based programs are required.

Documentation

The EPM11-FPGA example project on Github provides a great overview of setting up the FPGA build prerequisites and environment, as well as building and programming the FPGA example project to the board.

A EPM11-MCU example project on Github that provides a custom, board-specific MicroPython image is coming soon! See ‘Section 6’ of the Datasheet below for instructions on flashing a custom MicroPython image to the EPM11.
