SinoVoIP Releases $35 Banana Pi BPI-M2+ Board with Allwinner H2+ Processor

Banana Pi BPI M2+ board was first released with Allwinner H3 processor, but the same PCB can also be used with Allwinner H2+ and H5 processors since the processors are pin-to-pin compatible, and SinoVoIP intends to release three version of the board, and just launched BPI M2+ (aka BPI H2+) with Allwinner H2+ processor for $34.50 + shipping, $1.5 cheaper than the H3 version also listed on Aliexpress. If you shop around, and don’t order on the official SinoVoIP store, you may find cheaper price for the boards. As expected, the specifications have not changed apart from the processor:

  • SoC – Allwinner H2+ quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz
  • System Memory – 1GB DDR3
  • Storage – 8GB eMMC flash, micro SD card slot up to 64GB,
  • Video & Audio Output – HDMI with CEC support
  • Connectivity – Gigabit Ethernet, 802.11 b/g/n WiFi + Bluetooth 4.0 (AP6212)
  • USB – 2x USB 2.0 host ports, 1x micro USB OTG port
  • Camera – CSI Interface for 8-bit YUV42 CMOS sensor up to 1080p30
  • Expansions – 40-pin Raspberry Pi compatible header
  • Debugging – 3-pin UART header for serial console
  • Misc – Power, recovery, and u-boot buttons; Power and status LEDs, IR receiver
  • Power Supply – 5V/2A via power barrel (micro USB OTG port does not support power input)
  • Dimensions – 65mm × 65mm
  • Weight – 48 grams

The processors are not that different either, with Allwinner H3 supporting 4K video decoding and output up to 30 Hz, while H2+ is limited to 1080p60. The rest of the features look exactly the same. The company’s BPI M2+ page is all about the H3 version but most parts should be identical for the new boards. Supported operating systems include Android 4.4, Ubuntu 16.04 (Mate), Kano, Raspbian, Debian 8 and more according to the Download page, but none of them are likely to be working perfectly, and I’m not 100% sure they are working on the new H2+ board since they were all released last year, except Android 4.4 (Jan 2017). It might just be a case of updating the Device Tree (DTB) file however. [Update: I forgot the images are based on an ancient Linux 3.4 kernel, so not device tree here].

You may also wonder why Orange Pi Zero board with the same H2 processor sells for $7, while that new board goes for about $35… One of the reasons is that Banana Pi boards are  generally more expensive, but the price gap is mostly due to vastly different hardware specifications: 256 to 512MB DDR3, no eMMC flash, no HDMI output, Fast Ethernet, no camera support, smaller board, etc…

If the H2+ variant really provides Gigabit Ethernet I don’t believe in any differences between H2+ and H3 any more.

BTW: None of those vendor images use DT anyway. It’s still fex there and we know of zero adoptions necessary to switch H3 with H2+. You can run any BPi M2+ image on this BPi H2+ thingie as you can run any NanoPi NEO image (H3) on an OPi Zero (H2+) and vice versa. This will only change with the H5 variant due to different CPU cores there. Ah, and there’s one other exception: since this vendor forgot to implement voltage regulation all BPi M2+ are fed with 1.3V (schematics tell 1.2V and my BPi M2+ shows 1.4V instead —… Read more »

I thought the difference was in the VPU: the H3 can handle 4K but the H2+ is limited to 1080p.

Change the H2+ case test to 0 and you’re most probably already done

I didn’t get that.
You want to tell us that h2+ can be made playing 4k?

@itchy n scratchy No idea (I’m not that much into video/display stuff anyway). At least that’s one of the variants discussed today in linux-sunxi IRC: a software quirk limiting memory reservations based on chipid so that H2+ chips aren’t able to handle more than 1080p. What puzzles me a bit more is H2+ being said to lack Gigabit Ethernet capabilities so how is it possible to replace H3 with H2+ on a GbE equipped board (if they would use H2+/H3 internal Fast Ethernet PHY they would’ve to reroute the PCB — I don’t know whether it’s also possible to connect… Read more »

@tkaiser weird story, lets see what is found out in the near future, but your guess re licensing sounds pretty plausible to me…

However it’s not 100% related, this seems to give some interesting pointers to start digging deeper:

Yeah, let’s stop speculating for now. But I’m still curious what first BPi H2+ users report when running iperf3 against a GbE capable host. If they get 95 Mbits/sec max while ethtool is talking about ‘Speed: 1000Mb/s’ some might be ‘slightly’ annoyed. So let’s hope ‘missing Gigabit’ on H2+ is just not true 🙂

@tkaiser lets see if h2+ will find its corner…
