ULX3S on its first crowdfunding campaign

After many months of preparation, the team members at Radiona are ready to launch the ULX3S FPGA ESP32 crowdfunding campaign, planning to finally make 2020 what Hackaday described as “The Year of the Hacker FPGA” (*). Many people have worked on preparing the board and example code for world-wide distribution to all the makers and hobbyists worldwide. We believe this is one of the best developer boards ever – bringing together a vast array of features and capabilities in a fairly small sized and reasonably priced board.

The ULX3S has been actively developed for over 4 years and is the result of collaboration between Radiona – Zagreb Makerspace and FER – Faculty of Electrical Engineering and Computing – University of Zagreb, Croatia. Hobbyists, developers, and engineers from everywhere!

We invite you to checkout the main campaign page and help us bring the ULX3S to life by backing our campaign! Thank you for your support!
The ULX3S is a fully open source, compact, robust and affordable FPGA board equipped with a balanced spectrum of extra components and expansions. Although primarily developed as a teaching tool for mastering the principles of digital circuit design 1, a wide selection of useful features and interfaces enables it to serve as a broad spectrum module for installation in complex devices.

ULX3S uses powerful Lattice Semiconductor ECP5 series FPGA chip supported by the latest open-source toolchains. This makes the ULX3S one of the most powerful and desirable platforms for FPGA enthusiasts available today. ULX3S comes equipped with onboard WiFi, display, buttons, LEDs and storage. Flash it using the WiFi connection (over-the-air update), or with one of the bitstreams stored on SD card and browsed by onboard OLED display and buttons. Due to its battery-backed RTC, it can power down completely and wake up only on certain events making it useful for low power applications such as battery-powered remote sensor nodes. And if you’re not of the low-power type, onboard peripherals such as SDRAM, USB, Digital video out, onboard FM/ASK antenna, ADC and DAC can make it audio/video powerhouse for signal processing and synthesis, motor control or SDR cases. You can emulate arcade machines or retro computers like Minimig (Amiga) or modern systems like F32C (MIPS/RISCV). It has 56 GPIO pins, all routed as differential pairs and a PMOD compatible pinout, opening it to a wide range of expansion options. If you are just starting with FPGA, you can also use the ULX3S as powerful Arduino and program it using Arduino IDE in seconds.

It has been actively developed since 2016 and is the result of collaboration between Radiona.org – Zagreb Makerspace and FER – Faculty of Electrical Engineering and Computing – University of Zagreb, Croatia.
