Banana Pi BPI-S64 Core is a “Compute Module” based on Actions Semi S700 Processor

SinoVoIP has launched many development boards & SBCs under the Banana Pi brands, but so far they had not designed any system-on-modules (SoM). Banana Pi BPI-S64 Core is their first SoM, which they refer to as “Compute Module” for the compulsory Raspberry Pi reference, and it’s not based on Allwinner or Realtek processors used in many of their recent boards, but instead an Actions Semi S700 quad core Cortex A53 processor. Banana Pi BPI-S64 Core specifications: SoC – Actions Semi S700 quad core Arm Cortex-A53 processor with Arm Mali-450MP4 GPU with OpenGL ES2.0/1.1, OpenVG 1.1, EGL 1.5 support System Memory – 2GB LPDDR3 Storage – 8GB eMMC flash Edge Connector – 204-pin SO-DIMM connector Power Supply – PMIC on-board Dimensions – 67.5 x 30 mm The company also provides Banana pi BPI-S64 core kit for getting started with the module. Development kit preliminary specifications: SODIMM slot for Banana BPI-S64 Core […]

Orange Pi 3G-IoT SBC Launched for $24.90

We had two Arm Linux SBCs with cellular connectivity from Shenzhen Xunlong so far: Orange Pi 2G-IoT for 2G connectivity, and Orange Pi 4G-IoT with LTE support in Asia and Europe. But what if you needed 3G connectivity, and did not want to spend $45 on the 4G board? There was no option until today, but the company has just launched Orange Pi 3G-IoT with WCDMA (UMTS), TD-CDMA and CDMA2000 support. Orange Pi 3G-IoT-B board specifications: SoC – MediaTek MT6572 dual core Cortex A7 processor @ up to 1.2 GHz with Arm Mali-400 GPU System Memory – 512MB DDR2 Storage – 4GB eMMC flash, micro SD slot Display I/F – FPC connector for FWVGA display (854×480) Camera I/F – MIPI connector Audio – 3.5mm audio jack, built-in microphone, 2x solder pads for optional speakers Connectivity Cellular Nano SIM card slot 2G GSM – 850/900/1800/1900 MHz 3G WCDMA -(B1/B2/B5/B8), TD-CDMA, CDMA2000 […]

IOTA Tangle is a Blockless Distributed Ledger for the Internet of Things – Running a IOTA Full Node on Rock64 Board

A lot of efforts is going into distributed ledger technologies like the blockchain, and while I keep hearing blockchain is the future, there’s a lot of hype, and so far I have not seen that many practical use cases. But recently I saw Open Source Foundries – a new company announced at Linaro Connect US 2017 – participated in the IOTA blockchain BoF at the OpenIoT Summit 2018 showing a demo publishing sensor data to the IOTA Tangle. So maybe we have a practical application here… Sadly, there’s no video recording of the IOTA blockchain BoF, so instead let’s go to the IOTA website to find out more. What is IOTA? That’s the short description of the solution: An Open-Source Distributed Ledger The first open-source distributed ledger that is being built to power the future of the Internet of Things with feeless microtransactions and data integrity for machines. The key technology […]

Khadas Tone High Resolution Audio Board is Designed for Khadas VIM/VIM2, PCs, and Other SBCs

Khadas VIM and Khadas VIM2 are development boards powered respectively by Amlogic S905x and S912 processors that come with decent software support. The company also provides application specific add-on boards for their SBCs, and a while ago, I reviewed VIM2 with their dual tuner board and showed how to stream videos from my satellite dish or terrestrial antenna to the local network. Their latest solution is Khadas Tone board for high-quality audio applications. Khadas Tone “VIMs Edition” specifications: Multicore MCU – XMOS XU208-128-QF48 with 8x xCORE-200 cores up to 500 MIPS DAC – ES9038Q2M 32-Bit Stereo Mobile Audio DAC THD+N – ≤ 0.000337% @1KHz SNR – ≥ 120dB @ 10Hz~20KHz DNR – ≥ 120dB @ 10Hz~20KHz Crosstalk – ≥ 127dB @ 10Hz~20KHz Frequency Response – ±0.08 dB @ 10Hz~20KHz Sampling Frequency PCM: Up to 768KHz @ 32bit DSD: Up to DSD256 @ 1bit Clock Jitter Reference Clock Jitter < 3ps […]

Xiaomi Mi Router 4 is a $60 AC1200 Router with Three Gigabit Ethernet Ports

Xiaomi Mi Router 3 AC1200 router based on Mediatek MT7620A processor was launched in 2016 for just under $40 on online retailers. It had at least one caveat however, since it only supported Fast Ethernet. The company has now launched an upgraded version – Xiaomi Mi Router 4 -, still an AC1200 router, but equipped with a faster Mediatek MT7621A processor, and three Gigabit Ethernet ports. The new router sells for 199 RMB ($31 US) in China, but it’s also found for under $60 including international shipping on sites like Banggood or GearBest. Mi Router 4 (Miwifi 4) specifications: WiSoC – Mediatek MT7621A dual core MIPS processor @ 880MHz System Memory – 128 MB DDR3-1200 Storage – 128 MB SLC NAND Flash Wi-Fi 2.4GHz – 2X2 MIMO up to 300Mbps 5GHz – 2X2 MIMO up to 867 Mbps Wireless Security – WPA-PSK/WPA2-PSK encryption, wireless access control (black and white list), […]

FriendlyELEC Launches a Rockchip RK3399 SBC for $129. Meet NanoPC-T4

Earlier this year, we have a number of SBCs based on Rockchip RK3399 hexa-core processor from Orange Pi RK3399 to ODROID-N1, or Pine64 RockPro64 boards. FriendlyELEC has joined the fray with their NanoPC-T4, which they claim is the the smallest RK3399 based high-performance ARM board. The SBC comes with 4GB RAM, 16GB eMMC flash, dual-band WiFi module and an M.2 PCIe interface with NVME SSD support. NanoPC-T4 board specifications: SoC – Rockchip RK3399 hexa core big.LITTLE processor with two Arm Cortex-A72 cores up to 2.0GHz, four Cortex-A53 cores up to 1.5GHz, and a Mali-T864 GPU withsupport for OpenGL ES1.1/2.0/3.0/3.1, OpenVG1.1, OpenCL, DX11, and AFBC System Memory – 4GB dual channel LPDDR3 Storage – 16GB eMMC 5.1 flash, M.2 slot for NVMe SSD, 1x microSD slot Display / Video Output HDMI 2.0a up to 4K @ 60Hz withHDCP 1.4/2.2 DisplayPort 1.2 Alt Mode on USB Type-C LCD I/F – 1x eDP […]

A Closer Look at Mediatek MT8516 Cortex A35 SoM / Devkit for Android Things

Earlier this month, Google released Android Things 1.0, the first stable release for the IoT operating system, and announced several certified SoMs (systems-on-module) based on NXP i.MX 8M, Qualcomm SDA212 & SDA624, and MediaTek MT8516 SoCs. However at the time, beside some information about the processor itself, there was not many details about MT8516 system-on-module. Since then, MediaTek wrote a blog post about their Cortex A35 solution for Android Things & Google Assistant, so let’s have a look. First the MT8516 SoM is not exactly what I had expected, but instead a complete single board computer, and this is why they call it virtual SoM (vSOM). Google defines the latter as reference design provided by the chip vendors and certified by Google. Mediatek MT8516 quad core Cortex A35 vSoM / development board specifications: SoC – MediaTek MT8516 quad core Cortex A35 processor without GPU System Memory – 4Gbit (512MB) DDR3L […]
