1.1 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

• _ALL_ FTDI pins brought to test points

• 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 (short R16)

• _All_ FPGA pins including LED driver pins are brought to 0.1” headers

• qSPI ﬂash capability

• tinyFPGA bootloader compatible
