JackBurton wrote:I’m finishing up a small batch of 5.5 IO Boards, Horizontal SDRAM, and USB Hubs.
The IO Boards are fully populated, including a fan and heatsink. I’m waiting for the fan screws to come in and I’ll upload pictures.
The USB Hub boards come with standoffs for proper spacing under the main board. They also include a power cable splitter to allow for a single power supply to power both the de10-nano and USB board.
IO 5.5: $50
USB Hub: $40
Shipping is $5-10 in USA
SDRAM Univeral 3.1 (horizontal): $35
IO Board 5.5 fully populated with fan and Heatsink: $50
USB Hub: $40
Shipping is $5-$10 in USA

I would like to get a SDRAM board as well as a I/O board.
I live in France.
Anyone can help me ?
You will receive the e-mail (or PM) with offer.
Let me know if you won't receive it.

Please don't spread this false assumption. Temperature of FPGA doesn't go to dangerous even without any heatsinks. Far before temperature become critical for FPGA, some cores may become unstable as timings inside the core will break normal work. It especially affects ao486 and Minimig. Also with *ANY* enclosure the temperature will easily go beyond the acceptable degree.
Fan is required for stable work!

Yeah I was able to get a heat sink and an RTC though...the RAM boards were out within 1 day..hehe..hopefully I can get in on the next batch..do you make assembled I/O boards as well? I see you have only the pcb for sale.JimDrew wrote:I am now out of SDRAM boards! I have more RAM chips in route to stuff the existing PCB's I do have.
JimDrew wrote:No, I won't be making any assembled I/O boards. I will be producing a "Super Expansion" board for the DE-10 that can be used with the MiSTer project (and others). This board has the the basic I/O board features like VGA, audio out, push buttons, LEDs, SD card socket, as well as the SDRAM and RTC built into the same board. So, one board does everything.
