TinyFPGA-B-Series: common questions

What microcontroller does the TinyFPGA-B-Series use?

The TinyFPGA-B-Series is built around the ICE40LP4K-CM81, from the FPGA family.

How big is the TinyFPGA-B-Series PCB?

The TinyFPGA-B-Series measures 17.8 × 35.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TinyFPGA-B-Series?

34 components, from 18 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the TinyFPGA-B-Series design files?

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

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

Yes, under the terms of its GPL-3.0 license, which tinyfpga chose for the repository.

Can I test firmware for the TinyFPGA-B-Series 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.
