Radiona ULX3S Open Source Hardware ECP5 FPGA Development Board Launched for $99 and Up (Crowdfunding)

Last summer, we wrote about Radiona ULX3S education board combining a Lattice Semi ECP5 FPGA with an Espressif Systems ESP32 WiFi & Bluetooth WiSoC.

Designed for a digital logic course at the University of Zagreb, the board is open-source hardware with KiCAD hardware design files released on GitHub, and programmable with the Arduino IDE (FPGArduino) and ProjectTrellis open-source toolchain.

At the time, there was only a version based on Lattice ECP5 85F with 84K LUT, but they’ve now made versions with cheaper variants of ECP5 FPGA and launched the board on Crowd Supply.

Radiona ULX3S specifications:

The company has also released the workshop materials on Github with instructions for Linux and Windows. Support is available on Gitter where you can chat with other members of the community.

A comparison table for various Lattice Semi ECP5 development has been published as well. Note that it does not include the tiny, Feather board compliant, OrangeCrab that has just launched for $99 with ECP5 25F FPGA on GroupGets.

Radiona ULX3S is available in three versions with the following pricing:

If you feel up to it, you could also buy the bare board for $10, but you’d need to source and solder the components yourself. The crowdfunding campaign has just launched, and it’s going well so far for over $20,000 raised surpassing the $15,000 funding target. Shipping is free to the US, and $12 to the rest of the world with rewards expected to start shipping on June 16, 2020.
