## PCB Design Files, Designs, Documentation

The pico-ice is a small, low cost board with the Raspberry Pi Pico processor (RP2040) and a Lattice Semiconductor iCE40UP5K FPGA. The board features independent flash for the FPGA and RP2040, low power SSRAM, a couple of pushbuttons and a 3 color LED with _all_ FPGA and RP2040 pins brought out to easy to use 0.1" header pins (arranged as PMOD's) for fast prototyping.

The tinyVision.ai pico-ice Board Features:

* RaspberryPi RP2040 processor

* Lattice UltraPlus ICE40UP5K FPGA with 5.3K LUTs, 1Mb SPRAM, 120Kb DPRAM, 8 Multipliers

* _ALL_ RP2040 and 32 FPGA GPIO on 0.1” headers

* 4MB SPI Flash

* 8MB low power qSPI SRAM

* RGB LED, shared between the RP2040 and FPGA

* 2 pushbuttons, 1 dedicated and 1 primarily for processor reset during development but can be repurposed for user applications when not used for reset

* 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

* FPGA clock supplied by the RP2040, easy to program FPGA clock under SW control

* Examples for communicating to the FPGA over SPI

* Support for ultra low power sleeep mode: can shut down the RP2040 and FPGA while keeping the SRAM powered

Firmware features:

* pico-ice library to support drag-drop programming of the FPGA bitfile: no need of any dedicated programmer

* Alternate programming of the FPGA flash using DFU mode

* FPGA clock under RP2040 control

* Passthrough UART code enables transparent access to the FPGA's UART for debug/logging/control
