PCIe adaptor for multiple mini-PCIe chips #35
Comments
Hi @dsnet
Also looking if there's a better idea |
Another option: Sell PCIe cards with X number of Edge TPUs on it. The buyer specifies X, you sell a card that matches X,
At the end of the day, the buyer just wants EdgeTPUs in PCIe format. For this to work, I would expect the price to be somewhere within $20-$50 for every EdgeTPU. As an absurd pricing, consider the Asus PCIe accelerator card, which costs a whopping $1310. It's made up internally of 8x dual-core modules. Each dual core module costs $40, so 8*40 should be $320. So for the adaptor, we're paying for a markup of $990. That's just not economical. More money is going to the adaptor than the AI modules themselves. |
I used the QNAP QM2-4P-384 Quad M.2 PCIe Card. It has a built-in PCIe bifurcation, so that it works on older motherboards. With the dual core modules and the m.2 B+M adapters, that gives me eight TPUs: The QNAP is selling fairly cheap on ebay. It comes with both the low-profile and high-profile PC brackets, so it installs nicely on a regular desktop... |
could you let me know what adapter you are using exactly? Thanks. |
I bought four of the following adapters:

Hi, thank you for your work!
This might be a short-sighted request, but reflects current production conditions.
At present, the only module in stock is the single TPU in mini-PCIe form.
With a passive adaptor like these, I was able to get them to connect to my server. However, this is highly wasteful occupying a multiple-lane PCIe slot with only a card that uses a single lane.
Would you be able to produce an adapter card that converts multiple PCIe lanes in a single slot to multiple mini-PCIe? Say, perhaps 4 mini-PCIe or any number that makes sense.
