FPGA-ITX-01 FRONT 3D.png

Features

  • FPGA Adapter Card
  • 170x170mm, Mini-ITX card
  • 1 MB SRAM
  • 5V PS/2 keyboard connector
  • SD Card socket
  • 3:3:2 VGA (256 colors
  • 5V USB B (power only)
  • XIAO RP2040
  • Stereo Audio Jack
  • 3 I/O slots
    • Carry all J8 connections
    • Slot spacing 0.6"

Connectors

FPGA-ITX-01 FRONT CAD.PNG

J1, J13 - Stereo Audio Jack

  • 3.5mm stereo connector
  • Jack on card has priority over connection to chassis jack
    • Chassis front panel jack gets disconnected when jack is plugged into the card
  • Stereo pinout
    • Tip: This acts as the left channel signal wire
    • Ring: This acts as the right channel signal wire
    • Sleeve: This acts as the common return wire
  • J13 is header to case jack
  • Minimal LP filter
  • FPGA Sound on our GitHub
  • Using PWM to generate sound
  • How to Generate Sound using PWM
  • Run at frequency well above audio, say 44.1 or 48 KHz
  • Output of filter with 50% duty cycle will produce smoothed average voltage at the mid-point
  • Values > 50% duty cycle will produce a voltage higher than the average
  • Values < 50% duty cycle will produce a voltage lower than the average

FPGA-ITX-01 J1 -AUDIO.PNG

J2, J9 - 5V PS/2 keyboard connector

  • PS/2 connector
  • 5V to 3.3V level shifter

FPGA-ITX-01 J2 J8PS2.PNG

FPGA-ITX-01 J9 KBD.PNG

  1. CLK
  2. DATA
  3. +5V
  4. GND

J3 - 5V USB B (power only)

FPGA-ITX-01 J3 USB-PWR.PNG

J4 - 3:3:2 VGA (256 colors

  • VGA connector
    • 8-bit video (3:3:2)

FPGA-ITX-01 J4 VGA.PNG

J5 - SD Card socket

FPGA-ITX-01 J5 SD CARD.PNG

J6, U1 - XIAO RP2040

  • All pins are bought out to J1, J2 headers
  • Used as an FTDI card replacement
  • Tx/Rx/RTS/CTS brought to FPGA card
  • Connected to SD Card
    • SD Card is shared with FPGA
    • Can be used as replacement disk drive for BASIC Load/Save commands

FPGA-ITX-01 J6 QTPY.PNG

J7, J8 - FPGA Adapter Card

J7 - CPU I/O pins

  • Connects to SRAM, PS/2, VGA, SD card

Revision History

Rev 2

  • Moved upper right mounting hole
  • Fixed R23 DRC
  • Add pull-up resistors for input only pins
    • J8-35, 36, 57, 58
  • Move silkscreen pin numbers around FPGA a bit
  • Widen JTAG silkscreen block
  • Verified pin No Connects are correct
  • Added Rev 2 marking
  • Change R2H, etc to call out R/G/B (match PL)

Rev 1

  • Upper right mounting hole is in wrong spot
    • At 0.9" from edge, should be 0.9" from upper left mounting hole
    • Not big issue, no mechanical interference on board, just use 3 mounting holes
  • Yabs = 2.47480315, change to 2.87480315
  • R23 DRC error
    • Overshot pin on rear side
    • Verified right pin is connected
  • Input only pins do not support internal pull-ups
  • Missing Rev marking (use P-Touch label)
