UnAmiga ITX 

 

UNAMIGA ITX 

Hardware Specifications 

High-quality 4 layer board including an FPGA Board. 
24bit video DAC to output VGA 15khz/31khz output (depends 
on the core). 
I2S PCM5102 audio DAC with Dual stereo RCA jacks. 
Dual MicroSD for Data and Multicore capable. 
ATX connection. 
2 DB9 for Amiga Joystick and Mouse. 
4 USB ports with overcurrent protection.  
Wifi Module and RTC circuit included (battery not included). 
HDD, FDD, POWER, and FLASHING led on-board. 
Onboard STM32 for Multicore support. 
 

Note

: There are no serial, parallel, or external floppy ports 

available. Also, multicore support is available onboard, but to 
use this feature, among additional steps required, an 
additional 2x5 IDC female-female connector is required. Also, 
some of those cores like the NEXT core require an SRAM to be 
soldered on board (the footprint is below the FPGA module).  
 
The SDRAM part number is 

IS61WV5128BLL-10TLI for 512K or 

IS61WV10248BLL-10TLI (1MB).
