Checking the working temperatures
Our tests show that the passive cooling installed by the Banana Pi team over all the board’s chips works incredibly well. These are the temperatures recorded during R4 Pro operation. It’s also worth noting that the two fans built to push hot air out of the case perform excellently.

It is already on presale.
Yes, I know, thank you.
Hi, the main problem about the BPI R4 is its BE14 Wifi NIC (6 antennas and many shielding/noise problems).
In your pictures, we can clearly see the new BE19 NIC with 14 antennas: did you test it? Is it going to be released to the public this year? Thank you!
HI. Not yet, but from what I’ve heard, it should officially be released in a few weeks.
Thank you so much! Will you make a new post when the BE19 will be out? Did you have the R4 Pro for testing or these are just info from the company?
Not yet, but I’ll probably test the R4 Pro and the Wi-Fi expansion board and review them once both are ready and available.
For now, it’s just general news info.
