 UPDuino v3.0: PCB Design Files, Designs, Documentation

The UPDuino v3.0 is a small, low cost FPGA board. The board features
an on-board FPGA programmer, flash and LED with all FPGA pins brought
out to easy to use 0.1" header pins for fast prototyping.

The tinyVision.ai UPduino v3.0 Board Features:

  * Lattice UltraPlus ICE40UP5K FPGA with 5.3K LUTs, 1Mb SPRAM, 120Kb
    DPRAM, 8 Multipliers
  * FTDI FT232H USB to SPI Device
  * ALL 32 FPGA GPIO on 0.1" headers
  * 4MB SPI Flash
  * RGB LED
  * On board 3.3V and 1.2V Regulators, can supply 3.3V to your
    project
  * Open source schematic and layout using KiCAD design tools
  * Integrated into the open source APIO toolchain

Please see the wiki page for the changes that were implemented from
v2.1. Some salient features are:

  * 4 layer board with a solid ground plane, proper layout and
    decoupling for good signal integrity and FPGA operation
  * Access to on-board 12MHz oscillator using a jumper
  * All FPGA pins including LED driver pins are brought to 0.1"
    headers
  * qSPI Flash capable
  * tinyFPGA bootloader compatible

Here are some resources for you:

  * Documentation (beyond whats on this GitHub)
  * Discord channel
  * Schematic
  * AssemblyDrawing
  * Blinking LED

 Please fill out the survey to suggest improvements to this board. We
really appreciate the feedback and will make improvements as business
permits!

You can buy this board here:I sell on Tindie. For bulk orders, pelase
email us directly at: sales at tinyvision dot ai.
