A low cost FPGA development board for absolute newbies

A low cost FPGA development board for absolute newbies.

The icerink ecosystem tries to exploit this by building a complete browser centric FPGA workflow. Edit, synthesize and upload FPGA designs from within your browser.

Doing this lowers the boarding hurdle by not requiring the installation of toolchains. Just plug in the board and begin to play :).

The main source of inspiration for this board was the upduino by Gnarly Grey. We tried to build a similarly minimal and cheap board. The main Hardware feature, our board employs additionally, is the Microcontroller that is capable of speaking…

Iceskate: common questions

What microcontroller does the Iceskate use?

The Iceskate is built around the STM32F070F6P6, from the STM32 family.

How big is the Iceskate PCB?

The Iceskate measures 23.6 × 57.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Iceskate?

37 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Iceskate design files?

From the icerink/iceskate repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Iceskate design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which icerink chose for the repository.

Can I test firmware for the Iceskate without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
