The UPDuino v3.1 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.x 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
- Works with IceStudionightly/dev branch only at the moment
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/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
