Its main chip is the SC0914(13), from the RP2040/RP2350 family. Other key parts include the TLV1117LV33DCYR, TPD1E05U06QDPYRQ1, 157112V12700, W25Q32JVSSIQ and AP2112K-1.2TRG1. By type, the board carries 52 capacitors, 50 resistors, 10 diodes, 9 connectors, 7 ICs and 6 switches.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

This FPGA experimentation and development board was developped for efabless chipignite workshops and labs to serve as an easy to use experimentation board and stepping stone towards ASIC digital design, allowing for simple migration of design to Tiny Tapeout projects.

It is released as open hardware, and all the design files are included here, as akicad project.

Chipignite discover: common questions

What microcontroller does the Chipignite discover use?

The Chipignite discover is built around the SC0914(13), from the RP2040/RP2350 family.

How big is the Chipignite discover PCB?

The Chipignite discover measures 53.5 × 65.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Chipignite discover?

139 components, from 46 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 Chipignite discover design files?

From the efabless/chipignite_discover repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Chipignite discover design in my own project?

Yes, under the terms of its Apache-2.0 license, which efabless chose for the repository.

Can I test firmware for the Chipignite discover without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
