# Features
* Lattice iCE40-HX8K FPGA in 256-pin BGA.
* 32 MByte SDRAM (16M x 16).
* Serial configuration flash (at least 2 Mbit).
* Three Grove connectors.
* Two PMOD connectors.
* One 20x2 header with 3.3V, ground and 18 FPGA I/Os.
* Two SATA headers (for differential signals; don't know if they would work with SATA HDDs.)
* DIP switch with four SPST switches.
* Two momentary pushbuttons.
* Four LEDs.
* 100 MHz oscillator.
* 5.0 V jack for external power supply.
* 3.3 V and 1.2 V regulators.
* Adjustable voltage on one bank of FPGA I/O pins.
* 32 KByte HAT EEPROM.
* 40-pin RPi GPIO header.
