项目链接：ECP5 FPGA in an "S7 Mini" form factor

使用Lattice的ECP5 FPGA制作的FPGA核心板，板上带有64Mb的HyperRAM DRAM、MicroSD卡槽以及丰富的IO端口

关键特性：

• Lattice ECP5-12/25F FPGA in a caBGA256 package.
• 32 / 64 3V3 IO on 2.54mm / 1.27mm pitch grid.
• 64 Mbit HyperRAM DRAM.
• USB Full Speed (12Mbit) connection to FPGA over Type-C connector.
• MicroSD card support.
• 8 Multiplexed RGB LEDs.

参考了以下与ECP5相关的开源设计：

• Black Mesa Lab's S7 Mini for the form factor and feature set inspiration.
• Greg Davil and his OrangeCrab and Butterstick development boards.
• Matt Venn's Basic ECP5 design.
• SpriteTM / Hackaday's 2019 Supercon Badge.
• Luke Valenty's TinyFPGA-EX.
• 1BitSquared's HyperRAM PMOD for symbol and footprint.
• ECP5 Symbol from xesscorp's Kicad Schematic Symbol Library.
