Banana Pi M4

Recommended Posts

Banana Pi BPI-M4 use Realtek RTD1395 chp design ,it is a 64-bit quad-core A53 mini single board computer. It features 1 GB of RAM and 8 GB eMMC. It also has onboard WiFi for b/g/n/ac and BT 4.2. On the ports side, the BPI-M4 has 4 USB 2.0 ports, 1 USB TYPE C port, 1 HDMI port, 1 audio jack. support M.2 Key E PCIE 2.0 interface.

The RTD1395 is equipped with a high-performance quad-core CPU,ARM cortex-A53,with 512K L2 cache embedded. the RTD1395 also integrates and efficient ARM Mali-470 Graphic Processing Unit(GPU) to accelerate 2D and 3D graphics processing. For acceleration of this OSD and 2K user interface,the built-in Streaming Engine of the RTD1395 provides commonly used drawing functions.the CPU is dedicated to applications ,while most of the functions of the RTD1395 is dedicated to manipulating,decoding video streams in vaious formats.e.g. decoding 4K2K H.265,Full HD MPEG1/2/4/H.264/H.264 MVC,AVC/VC-1,VP8,VP9,AVS,AVS plus,HD JPEG,etc. Video DSP can also handle encoding of up to Full HD with H.264 format.Video decoding and encoding can run simultaneously.

Hi @Nora Lee
Very weird choice of board to call the BPi M4.

I don't have the M3, but isn't the M3 a lot more powerful and more feature rich?
Could you explain more about why Sinovoip chooses this as successor?
I don't really understand it. 100Mbps ethernet(while using a realtek SoC), all USB2, no SATA, ...
I don't know why or who this board is for.  I would liked to have seen it with HDMI-in. 

Many people would want a cheaper SBC with HDMI-in.

What will the price be? When is it available?
I'm always willing to review it.

Greetings.

just BPI-W2 support HDMI-in  , this is limited by chip .

 

BPI-M4 with M.2 interface and 8G eMMC flash on board.

Isn't there a simular SoC with HDMI-in? I thought I red somewere this was the cheaper version of that SoC.  Here-> https://www.cnx-software.com/2019/02/13/banana-pi-bpi-m4-rtd1395-board-raspberry-pi/
A small, cheap SBC with HDMI-in and Linux support for encoding it. That I'd buy and many of my viewers.


Then I wouldn't mind having 100Mbit/s ethernet and USB2.
Having an SBC for this would make life easier compared to the HDMI-capture box I'm using now. I never know what it is recording until I see it afterwards.

The W2 looks great, but it's too expensive not knowing if it'll work well for my goal.
Keep on making great stuff. I love all SBC's.
Greetings.

Mini-PCIe is good a thing, you've got this one right!

-But the specs need to be better on a SBC today. RockPro64 is doing things the right way; they pack the SBC with good specs while keeping the price as low as they can, resulting in a board with great specs, for a slightly higher price than the average boards (but it'll pay for the end-user to get this board rather than the lower priced ones).

 

My personal priority list:

PCIe2.0 or PCIe3.0 (x4 or more if possible).

CPU-native 6G SATA (at least one port, but 3 ports would be very attractive)

Low power consumption.

GbE or faster (2.5GbE, 5GbE or even 10GbE)

Choice of 1GB, 2GB or 4GB LPDDR3 or LPDDR4.

Cortex-A57 or Cortex-A72 (or higher).

HDMI 2.0a output (or better).

 

Most casual users would expect to be able to use a SBC to play back video in very good quality.

The world's most cost-effective database cluster node:

 

Best multi-core A72 or A73

4GB fastest & widest RAM possible

M.2, physical 2280 slot, PCI3 x4 for NVMe

Gigabit Ethernet

Power via barrel jack

"Big Metal Block" heat sink

 

For node maintenance, a serial console on micro USB port, USB3 type A for backup media/emergency boot

 

Headless - No HDMI.

 

RK3399 would suit.  Marvell Armada 8040 is far too expensive.  Amlogic S922x has one measly PCIe.
