README
pmod_microsd/README.mdPMOD_MICROSD
The Pmod MicroSD provides a microSD card slot to any board that has 3.3V logic and is pin compatible with a 12-pin Pmod port capable of SPI communication.
This board is specially designed to adapt to VCU118, and the pull-up resistor for SDIO is modified to 330 ohm.

Introduction
PMOD
This design complies with Digilent Pmod™ Interface Specification 1.2.0.
Note that the pin sequence numbers on the digilent PMOD specification are inconsistent with the PMOD pin sequence numbers of AMD VCU118 on the document. Essentially they are the same, but the numbering of AMD VCU118 uses a double-column staggered odd-even arrangement. Here is their mapping relationship.
| PMOD PIN | VCU118 PIN | SDIO FUNCTION | SPI FUNCTION |
|---|---|---|---|
| 1 | 1 | DAT3(D3) | #CS |
| 2 | 3 | CMD | MOSI |
| 3 | 5 | DAT0(D0) | MISO |
| 4 | 7 | CLK | SCLK(SCK) |
| 5 | 9 | GND | GND |
| 6 | 11 | 3P3V(VDD) | 3P3V(VDD) |
| 7 | 2 | DAT1(D1) | NC |

| 10 | 8 | #WP | #WP |
| 11 | 10 | GND | GND |
| 12 | 12 | 3P3V(VDD) | 3P3V(VDD) |
LED
There are two LEDs on the PCB, the yellow one is the card detection indicator and the orange one is the power indicator.
| LED | COLOR | FUNCTION | ON | OFF |
|---|---|---|---|---|
| 1 | Yellow | Card detection indicator | MicroSD Card inserted | No MicroSD card |
| 2 | Orange | Power indicator | Power on | Power off |
Special signal
Among them, the #WP signal is constant high level. If the WP signal is
low, please check the power supply and there may be a fault.
| NAME | HIGH | LOW |
|---|---|---|
| #DET(#CD) | No MicroSD card | MicroSD Card inserted |
| #WP | Write protect is off | This state is impossible |

Questions
How big is the Fpga candelabra PCB?
It measures 280 × 111.2 mm and has 12 copper layers, 1.79 mm thick.
What parts does the Fpga candelabra use?
738 parts, built around the CSD95491Q5MC, LSF0108PW, SN74LVC1T45DCK and PCA9306DC. 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 Fpga candelabra KiCad files?
From the chipsalliance/rocket-pcb repository on GitHub, at the commit this page was made from: the board is fpga_candelabra/fpga_candelabra.kicad_pcb and its schematic fmc_basic_peripheral/fmc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fpga candelabra design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
