BPI-R4 back and wifi7 seatsink
1 Like
I guess this does not fit into the metal case.
Nice - I used a normal heatsink, but this one has screws 
Now the usual question: Where can I buy this? Could not find it on Aliexpress yet?
Nice heatsink, really nice solution, but what about connecting the heatsink to the bottom plate of the case? Because the heatsink is upside down oriented and there is not any fan, cooling is not efficient as it could be. I think, that we still need the heat get out from the case somehow.
If you’re talking about the official CNC case, I have two MOD ideas:
- open a heat-sink shaped hole at the bottom. Place your CNC case upside down and move the rubber feet accordingly. Or keep the original top-bottom design, rase the bottom with taller rubber feet. Or,
- trim the new heat-sink to fit into the existing limit of space. Less efficient but might still be workable thermally
I wonder if the new heat-sink will help to lower noise-floor of the BE14. @Betonmischer

Good morning,
I sent an email to [email protected] to ask whether the new BPI‑R4 back and WiFi‑7 heatsink will finally be put on sale.
I have finally received all the products of the new BPI‑R4 Pro.
I would like some more information about whether it will be sold on https://www.bpi-shop.com/heatsink.html,
or, alternatively, on AliExpress.
Above all, do you have a release date?
Thank you if you can also share this information through this channel, in case other users are also waiting.
Kind regards.
All the accessories will be sold in bulk. We are currently accelerating the mass production process as the first batch of BPI-R4 Pro has been sold out. We will have new batches available this month, and everything will get better. We also hope that everyone can offer good suggestions, and we will listen carefully.
Good morning, I sent you a private message regarding my motherboard, which I purchased from Proventa’s official store. It’s defective.
I’m waiting for you or someone from the store to reply to my messages, which include all the logs of the corrupted NAND I received.
Besides the NAND malfunctioning, the SD card doesn’t even boot, as I’ve shown you. I hope you can please tell me how to process the return and send me a new, working motherboard.
I look forward to hearing from you.
Good morning, thank you for your response. I initially sent it to [email protected], and later to [email protected] and [email protected].
You also have a private message with all the information.
It has all the logs, the NAND is corrupted and malfunctioning.
The SD card doesn’t even boot; they have photos of everything and complete logs.
I’m waiting for you to tell me how to fix it, whether with a simple image change, or if my motherboard is defective. Even the reset button doesn’t work.
Looking forward to hearing from you.
Thank you and best regards.
For sdcard,try to reduce speed in official image from 52 to 48mhz in uboot and linux.
Good morning frank-w, the problem is that the board is defective — the NAND/OpenWrt doesn’t even work properly, you can’t even install anything on the SD card. You have all the logs that show errors when booting the NAND, many errors, as well as many more tests provided for the NAND. The board arrived defective.
My board was one of the first pre-order units; I am waiting for an official response so they will replace it.
But thank you for your advice.
Regards
We will conduct a reproduction test to address the issue you encountered.
If you encounter any further usage-related problems, we suggest you create a separate thread. This thread is for discussing heatsinks.
