# Alhambra II FPGA board

Open FPGA for makers

![](https://github.com/FPGAwars/Alhambra-II-FPGA/raw/master/wiki/V1.0/Alhambra-II-01.jpg)

## Features

* iCE40HX4K (Lattice) FPGA development board (8K using opensource toolchain)

* Open hardware

* Compatible with the opensource [icestorm toolchain](Compatible with the opensource icestorm toolchain) and [Icestudio](https://github.com/FPGAwars/icestudio)

* Arduino like board: similar pinout than Arduino one

* You can Reuse most of available shields

* Control your robots / printbots from an FPGA

* FTDI 2232H USB device allows FPGA programming and UART interface to a PC

* ON/OFF electronic switch (turn off your mobile robot easily, switching on does not overload your USB port)

* 8 general purpose LEDs (user LEDs)

* 2 general purpose pushbuttons

* 32Mb flash memory for up to 30 bitstreams or user data

* 20 Input/output 3.3V (5V tolerant) pins

* All I/O pins include 200 ohms serial resistors for direct LED activation

* 4-Channels, 12 bits A/D converter

* Cold boot pins accessible from GPIO

* Switching regulators for high frequency processing at low power input

* 12 MHZ MEMS oscillator

* Reset pushbutton

* USB power supply, two connectors (up to 4.8A)

* Power pins and I/O pins allow permanent shortcircuit
