About the BosonFrameGrabber PCB

BosonFrameGrabber is an open source FPGA PCB design by gregdavill, published on GitHub under the MIT license. It is a 4-layer board measuring 63 × 63 mm, with 64 components from 33 distinct parts.

Its main chip is the LFE5UM-25F-6MG285C, from the FPGA family. Other key parts include the TLV70725PDQNT, SN74LVC1T45DRLR, S27KS0641DPBHI020, Boson and AT25SF081-MAHD-T. By type, the board carries 24 capacitors, 18 resistors, 10 ICs, 4 connectors, 3 switches and 3 diodes.

From the project

Simple but Small Frame Grabber

Development BigBoard (Do not use! known errata)

Due to supply issues of the ECP5 in cs285 I developed this PCB to start work on firmware. Despite many errata the board was functional (after mods) and did aid in fw development.

ECP5 8MB/16MB HyperRAM: high density, low pin count. 1MB QSPI Memory (XSON 3x2 package) MicroSD socket MEMs Oscillator JST GH SM06 locking Data/Power connector JTAG on GH SM06 2x 5V tolerant I/Os on connector 1x LED 240x240 IPS LCD. (used on NANO v6, MIPI interface)

BosonFrameGrabber: common questions

What microcontroller does the BosonFrameGrabber use?

The BosonFrameGrabber is built around the LFE5UM-25F-6MG285C, from the FPGA family.

How big is the BosonFrameGrabber PCB?

The BosonFrameGrabber measures 63 × 63 mm, has 4 copper layers and is 1.2 mm thick.

How many components are on the BosonFrameGrabber?

64 components, from 33 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 BosonFrameGrabber design files?

From the gregdavill/boson-sd-hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the BosonFrameGrabber design in my own project?

Yes, under the terms of its MIT license, which gregdavill chose for the repository.

Can I test firmware for the BosonFrameGrabber 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.
