Key Features
- Largest ECP5; LFE5UM5G-85F
- PCIe 2.0 x2 card edge connector on two SERDES channels
- Remaining two SERDES channels on M.2 E-key connector
- 1GByte x32 DDR3L (two x16 chips)
- Dedicated HDMI output, using TFP410 serialiser
- 1000BASE-T GbE connector with RGMII PHY
- USB-A 2.0 host connector with ULPI PHY
- FT2232H for debug JTAG and UART/FIFO with type-C connector
- PCIe, external 12V or USB power input
- 12 bicolour (tristate) user LEDs, 4 user buttons, 8 user DIP switches
- 128Mbit QSPI flash for boot and data
- microSD card connector
- Dual PMOD connector with extra "middle" IO pins
- As many remaining IO as possible on high speed FFC connectors with a differential optimised pinout (3x 24 IO). Selectable 1.8V/2.5V/3.3V
Layout
- PCIe card form factor
- At least Ethernet, USB-A, USB type-C power/debug and HDMI out
- Other connectors probably would have to be on other sides. FFC connectors probably on top so they can loop over to another card to form a 2-slot card (e.g. with ADCs/DACs for SDR/DAQ)
Possible accessories using high-speed FFC connectors
- MIPI DSI smartphone-style LCDs
- MIPI CSI-2 cameras
- High speed ADC/DAC
- HDMI in/out, direct or using serialiser chip
- LVDS video in/out for LCDs or block cameras
- Breakout board to dual or triple PMOD

Questions
How big is the Ecp5 mainboard PCB?
It measures 200 × 111.2 mm and has 8 copper layers, 1.6 mm thick.
What parts does the Ecp5 mainboard use?
512 parts, built around the TPS62823DLC, TLV75712PDRV, TPS2041BD and BSH111BKR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ecp5 mainboard KiCad files?
From the gatecat/TrellisBoard repository on GitHub, at the commit this page was made from: the board is hardware/ecp5_mainboard/ecp5_mainboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ecp5 mainboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask gatecat before reusing the design.
