Open source iCE40 FPGA board

Olimex preparing iCE40HX1K-EVB.It is first iCE40 FPGA which works with ICESTORM FOSS toolchain.

It`s 5x5 cm 4 layer board with iCE40HX1K on it, 512KB 10 nS fast SRAM, UEXT as programming connector, so you can program it with OLinuXino (which can run also the tool chain on it) or with Olimexino-328 or any other boards we have with UEXT.
All free iCE40HX1K singals are available on right angle bus connector, to this bus connector we designed 4 additional boards:

- iCE40-ADC fast 100Mhz ADC with BNC input connector so you can make Digital Storage Oscilloscope with p to 512 KB buffer
- iCE40-DAC fast 100Mhz DAC with BNC output connector will allow you to make DDS generator with odd forms using the on board SRAM
- iCE40-DIO fast IO with level shifter with programmable by I2C DAC threshold in range 1.5-5.5V, so you can capture digital signals with different levels making inexpensive Logic Analizer
- iCE40-IO with VGA and PS2 keyboard connectors board
- iCE40-IO will allow you to emulate small retro computers.

All additional modules are stackable and the bus pass through them, so you can stack more than one ADCs or more than one DACs etc if you need more IO.
