Pico2-ice

Powered by Raspberry Pi!

The pico2-ice is a small, low cost board with the Raspberry Pi Pico processor (RP2350) and a Lattice Semiconductor iCE40UP5K FPGA. The board features independent flash for the FPGA and RP2350, low power SSRAM, a couple of pushbuttons and a 3 color LED with all FPGA and RP pins brought out to easy to use 0.1" header pins (most arranged as PMOD's) for fast prototyping.

The tinyVision.ai pico-ice Board Features:

• Raspberry Pi RP2350B processor
• Lattice UltraPlus ICE40UP5K FPGA with 5.3k LUTs, 1Mb SPRAM, 120Kb DPRAM, 8 Multipliers
• All RP2350 and 32 FPGA GPIO on 0.1” headers
• 4MB SPI Flash
• 8MB low power qSPI SRAM
• 2 RGB LED, one for the RP2350 and one for the FPGA
• 2 pushbuttons, 1 for RP2350 boot mode that can also be used for other functions, and one for the FPGA
• On board 3.3V and 1.2V Regulators, can supply 3.3V to your project
• Open source schematic and layout using KiCAD design tools
• 4 layer board with a solid ground plane for good signal integrity

Board and Firmware features:

• MicroPython support: Shipped with Micropython support for FPGA programming and clock control.
• FPGA clock supplied by the RP2350, easy to program FPGA clock under control of the RP2350
• RP2350 can program the FPGA directly or the dedicated FPGA flash.
• 8 bit wide bus between FPGA and RP2350, can be used for qSPI, UART etc.

Boards are fully tested and programmed with a Micropython port and blinking LED FPGA image before shipping. Included are four dual PMOD's (not soldered on to give you flexibility in mounting). Please note that a USBC cable is not included!

This board was designed as a community effort with many people contributing to the board and firmware development. Thank you to all those who helped review and try this out, this board wouldnt be possible without you!
