TinyFPGA-BX: common questions

What microcontroller does the TinyFPGA-BX use?

The TinyFPGA-BX is built around the iCE40-LP8K-CM81, from the FPGA family.

How big is the TinyFPGA-BX PCB?

The TinyFPGA-BX measures 17.8 × 35.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the TinyFPGA-BX?

41 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the TinyFPGA-BX design files?

From the tinyfpga/TinyFPGA-BX repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the TinyFPGA-BX design in my own project?

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

Can I test firmware for the TinyFPGA-BX without the hardware?

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