About the Trugbild PCB

Trugbild is an open source FPGA PCB design by JakubKajzer, published on GitHub. It is a 4-layer board measuring 85 × 40 mm, with 90 components from 19 distinct parts.

Its main chip is the XC3S50A-4VQG100C, from the FPGA family. Other key parts include the AS4C32M8SA-6TIN, MIC5365-3.3YD5, LDK130PU12R_DFN6 and MX25L1636EM2I-08G. By type, the board carries 30 diodes, 29 capacitors, 14 resistors, 7 inductors, 5 ICs and 4 connectors.

From the project

An FPGA working in serial with HDMI, for some real live video modifications

- Xilinx Spartan 3 XC3S50A - 2MB Flash memory - 32MB DRAM memory - Possibility to power device only from HDMI or from external input

- [x] Order PCB fabrication - [ ] Order elements - [ ] Solder everything - [ ] First run - [ ] Try to run device only with power from HDMI (max. 50mA@5V) - [ ] Make and test if device can transmit HDMI at Full HD - [ ] Make some video modification while transmitting - [ ] Try to add some kind of neuron network to face recognition - [ ] Try to cover detected faces with some picture or someone face :) ## Comments ### Make PCB This point took me many hours of…

Trugbild: common questions

What microcontroller does the Trugbild use?

The Trugbild is built around the XC3S50A-4VQG100C, from the FPGA family.

How big is the Trugbild PCB?

The Trugbild measures 85 × 40 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Trugbild?

90 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Trugbild design files?

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

Can I use the Trugbild design in my own project?

The repository has no license, so all rights stay with JakubKajzer. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Trugbild 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.
