Tweet Several companies are already offering development kits for Amazon AVS (Alexa Voice Service), but as we’ve seen in the past, those are rather expensive with far-field kits such starting at $349 with kits such as Synaptics AudioSmart 4-Mic Development Kit, or Intel Speech Enabling Developer Kit, and hands-free kits being barely cheaper at $299 and up. But there will soon be a cheaper solution, as Allwinner and SinoVoIP (aka Banana Pi) are working on “SoC-Only 3-Mic Far-Field Dev Kit for Amazon AVS” that includes 3 microphones, and works without special DSP, relying instead on Allwinner R18 processor’s audio codec and capabilities. Allwinner SoC-Only 3-Mic Far-Field Dev Kit for Amazon AVS (aka R18-AVS-EVK) specifications: SoC – Allwinner R18 quad-core Cortex-A53 processor @ 1.15GHz with Mali400MP2 GPU System Memory – 1GB DDR3 Storage – 8GB eMMC flash Video Output – HDMI Audio – 6x Microphones, 2x AEC, AUX and headphone output; GMEMS voice recognition algorithm Connectivity – Dual band WiFi, Bluetooth 4.0 …
Tweet Banana Pi M2 Magic development board was first unveiled in February of this year with an Allwinner R16 SoC, 512 MB RAM, and 8GB eMMC flash, and its main selling points were support for MIPI DSI LCD displays, CSI cameras, and 3.7V LiPo batteries. AFAIK SinoVoIP never sold that version of the board, at least on Aliexpress. Possibly due to the intricacies of Allwinner business units, the company has now officially launched Banana Pi M2 Magic (aka BPI M2M), but replaced Allwinner R16 by the similar Allwinner A33 processor, and removed the 8GB eMMC flash to bring the price down to $23 plus shipping. The “old” Allwinner R16 based Banana Pi M2 Magic board will apparently be sold as M2 Magic Plus soon. Banana Pi BPI-M2 Magic (A33) specifications: SoC – Allwinner A33 quad core ARM Cortex-A7 processor with ARM Mali 400 MP2 GPU System Memory – 512MB DDR3 Storage – micro SD slot Display Interface – 4-lane MIPI …
Tweet I’ve reviewed several Realtek RTD1295 platforms with Zidoo X9S and Eweat R9 Plus, and I was generally impressed by the storage, Ethernet, and WiFi performance. 4K video playback was good too, as long you don’t have any 4K H.264 videos at 30 fps or more. Most devices would also run Android and OpenWrt side-by-side bringing the best of both operating for respectively apps & multimedia, and server functions. HDMI input – with PVR, time-shifting and PiP functions – was also a bonus, However so far, nobody cared to design a maker board powered by RTD1295 processor. Since then we’ve learned Realtek was working on RTD1296 processor with even more Gigabit Ethernet, USB 3.0, and SATA interfaces, and SinoVoIP has now designed a board based on the SoC called Banana Pi BPI-W2. Banana Pi BPI-W2 preliminary specifications: SoC – Realtek RTD1296 quad core Cortex A53 processor with ARM Mali-T820 MP3 GPU System Memory – 2GB DDR4 RAM Storage – 8GB …
Tweet Banana Pi BPI-R2 is a multimedia router board powered by MediaTek MT7623N quad core processor with 2GB RAM, 5 Gigabit Ethernet ports, up to two SATA ports, two USB 3.0 ports, HDMI output, and I/O headers. The board is not for sale yet, but the company has recently released the source code with U-boot and Linux 4.4.70, as well as a datasheet for MediaTek MT7623N processor. The source code can be found on Github, so let’s see if we can build it:
git clone https://github.com/BPI-SINOVOIP/BPI-R2-bsp
sudo apt install gcc-arm-linux-gnueabihf
new build.sh default select BPI-R2-720P and pack all boards
BPI-R2-720P configured. Now run `make`
This tool support following building mode(s):
1. Build all, uboot and kernel and pack to download images.
2. Build uboot only.
3. Build kernel only.
4. kernel configure.
5. Pack the builds to target download image, this step must execute after u-boot,
kernel and rootfs build out
6. update files for SD
7. Clean all build.
Please choose a mode(1-7): 1
After a couple of minutes, the build would end with:
For the very last step, it asks you to login as root / sudoer, which it should not do… But we end up with the images, so at least it builds:
ls -lh ./SD/

MediaTek has also been active by committing patchsets for MT7623 to the Linux Kernel Mailing List, so mainline Linux is an eventual possibility for BPI-R2 board. We just don’t have a clear view …
Tweet SinoVoIP has unveiled yet another new board with Banana Pi BPI-M2 Berry this week-end. It’s actually quite similar to Banana Pi BPI-M2 Ultra board, by they replaced Allwinner R40 with Allwinner V40 processor, removed some features, and use Raspberry Pi 3 form factor. If we look at Allwinner V40 product brief we can see the specifications look almost identical, with V40 potentially exposing an extra CAN bus. The company’s announcement was very confusing since they show Banana Pi BPI-M2 Berry board with Allwinner R40 instead of Allwinner V40. Banana Pi BPI-M2 Berry specifications: SoC – Allwinner V40 quad Core ARM Cortex A7 processor with ARM Mali-400MP2 GPU System Memory – 1G DDR3 SDRAM Storage – micro SD slot, SATA interface Connectivity – 1x Gigabit Ethernet port, 802.11 b/g/n WiFi and Bluetooth 4.0 (AP6212 module) Video Output – HDMI 1.4 port up to 1080p60, 4-lane MIPI DSI display connector Audio I/O – HDMI, 3.5mm headphone jack, built-in microphone USB – …
Tweet Banana Pi BPI-M64 board was launched with Allwinner A64 processor, but a few days ago, I noticed the board got an option for Allwinner R18. Both processors are likely very similar since they are pin-to-pin compatible, and Pine64 was first seen with Allwinner R18, so I did not really feel it was newsworthy. But today, Google announced Google Cloud IoT Core cloud service working with a few app partners such as Helium and Losant, as well as several device partners including ARM, Marvell, Microchip, Mongoose OS, NXP… and Allwinner, having just announced the release of an Allwinner R18 SDK with libraries supporting Google Cloud IoT Core. Let’s go through the board specifications first which are exactly the same as for the original BPI-M64 board, except for the processor: SoC – Allwinner R18 quad core ARM Cortex A53 processor with Mali-400MP2 GPU System Memory – 2GB DDR3 Storage – 8GB eMMC flash (16, 32 and 64GB options), micro SD slot …
Tweet 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 …
Tweet Allwinner R16 is a quad core Cortex A7 processor found in Nintendo NES Classic Mini game console, but so far there was no development board based on the processor apart from Allwinner Parrot board that does not appear to be for sale. But Banana Pi has designed their own R16 development board, and released some information about BPI-M2 Magic board. Banana Pi BPI-M2 Magic specifications: SoC – Allwinner R16 quad core ARM Cortex-A7 processor with ARM Mali 400 MP2 GPU System Memory – 512MB DDR3 Storage – 8 GB eMMC flash (option: 16, 32 or 64GB) + micro SD slot Display Interface – 4-lane MIPI DSI connector Camera Interface – CSI connector supporting up to 5MP sensor, 1080p30 H.265 video capture Video Decoder – Multi-format FHD video decoding, including Mpeg1/2, Mpeg4, H.263, H.264, etc H.264 high profile [email protected] Audio – On-board microphone Connectivity – Wifi 802.11 b/g/n, Bluetooth 4.0 LE (AP6212) USB – 1x USB 2.0 host, 1x micro …
