- 5V USB B (power only)
- QTPy USB
- Used as a USB to Serial converter
- Stereo Audio Jack
- PWM Sound Output with Low Pass Filter
- 3 I/O slots
- Carry all J8 connections
- Slot spacing 0.6"
- Current: 130mA with XIAO RP2040
1 MB SRAM
- 1MB SRAM
- IS62WV10248EBLL-45TLI, SRAM. Async, 1Mbx8, 45ns
- For banked use in CP/M and as RAM Disk in other 8-bit micro designs
Connectors
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
J2, J9 - 5V PS/2 keyboard connector
- PS/2 connector
- 5V to 3.3V level shifter

J5 - SD Card socket
J6, U1 - XIAO RP2040
- XIAO RP2040
- Can power the card from the USB on this card
- 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

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 (near XAIO USB/Serial interface) 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 to install in case
- Yabs = 2.47480315, change to 2.87480315
- R23 DRC error
- Overshot pin on rear side
- Verified right pin is connected
- Input only pins (using Cyclone 10) do not support internal pull-ups
- Missing Rev marking (use P-Touch label)
- Tested/works
- Video
- PS/2 keyboard
- SD card
- 5V input
