Hello!! It's Joseph

 from lambdaconcept     ECPIX-5 comes in two FPGA variants: LFE5UM5G-45F (45K LUTs) or the larger LFE5UM5G-85F (85K LUTs).     * Lattice ECP5-5G FPGA with 5Gbit/s SERDES.     * 4Gb (256MB) of DDR3L RAM     * 256Mb (32MB) Quad-SPI Flash     * Built-in JTAG and serial USB interface     * USB-C port for USB 2 and USB 3 operation     * HDMI 1.4b transmitter     * Gigabit Ethernet     * Full size SATA port     * microSD (UHS-II capable)     * Four RGB LEDs     * Eight industry standard PMOD connectors Applications:     * nMigen/Migen/LiteX programming     * USB 2/USB 3 prototyping     * Game console emulation     * Software Defined Radio     * Customizable RISC-V SoC  using open source toolchains, and schematics available.  -45F an...

  The ULX3S was developed primarily as an educational tool for undergraduate-level digital logic classes, based on Lattice ECP5 FPGAs. with the hard work form Radiona and others, it features a wide selection of components and interfaces( USB, GPDI, SPI, WiFi and BT(from ESP32), Audio,SD, OLED, JTAG,...) and open souce toolchains: yosys, nextpnr, trellis, fujprog, and many others some history and its predecessor ULX2S Radiona Org official webpage and comparison chart quick start guide github: github ulx3s aggravator links in one page  radiona   EMARD (Marko Zec, U of Zagreb, Croatia) Goran on PMOD boards gojimmypi kost and his ghdl examples LiteX on ECP5 LFE5U-45F zzz instant messaging:  twitter getter.im news: the beginning: odysseus project cnx software   hackaday another similar board, ECPIX-5 from lambdaconcept
