Resonance
About the Resonance PCB
Resonance is an open source FPGA PCB design by gregdavill, published on GitHub. It is a 4-layer board measuring 45 × 35.5 mm, with 60 components from 22 distinct parts.
Its main chip is the ECP5U-12-CABGA256, from the FPGA family. Other key parts include the W25Q32JVZP, TLV62569DRLR and AP2127K-2.5. By type, the board carries 29 capacitors, 19 resistors, 4 ICs, 4 connectors, 1 crystal and 1 fuse.
From the project
1 circuit board design a day for 31 days.
This board is intended to sit between the Fundamental and Harmonic board and monitor the SPI data running to the display. The ECP5 on-board will mirror the display and output a copy to a digital monitor.

Resonance: common questions
What microcontroller does the Resonance use?
The Resonance is built around the ECP5U-12-CABGA256, from the FPGA family.
How big is the Resonance PCB?
The Resonance measures 45 × 35.5 mm, has 4 copper layers and is 0.8 mm thick.
How many components are on the Resonance?
60 components, from 22 distinct parts. The full bill of materials is listed on this page.
Where can I download the Resonance design files?
From the gregdavill/advent-calendar-of-circuits-2020 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Resonance design in my own project?
The repository has no license, so all rights stay with gregdavill. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Resonance 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.
