Howchip is Teasing ExSOM-7420SB Development Board Based on Samsung Exynos 7420 Processor

We’ve already seen a few Cortex A53 boards announced in the last few months with Nobel64, as well as Hikey & DragonBoard 410c 96Boards, but none of them are based on the more powerful Cortex A57 cores. Howchip is going to change that with the upcoming ExSOM-7420SB single board computer featuring Samsung Exynos 7420 processor used in Galaxy S6 smartphone. The company has released very few details about the board, except the block diagram above that shows Exynos 7420 with 3GB LPDDR4 PoP memory, and various interfaces such as USB 2.0/3.0, UFS/eMMC, Ethernet, HDMI, MIPI DSI, Camera, as well as Wi-Fi and Bluetooth connectivity. The board will support Android 5.0 Lollipop 64-bit. No word about Linux. That’s the video teaser, but you won’t learn much… More details should eventually be published on ExSOM-7420SB product page. Alternatively, Hardkernel will also probably launch an ODROID-XU4? board based on the latest Exynos 7 […]

MXCHIP EMW3162 is a $10 Low Power Wi-Fi Module for IoT Applications

You can’t beat ESP8266 Wi-Fi modules on price to add Wi-Fi to your IoT projects, but Hackaday found a new Wi-Fi module by Shanghai MXCHIP Information Technology that sells for $10 on Seeed Studio or Amazon US, that should be better suited to battery operated project thanks to a lower power consumption. EMW3162 also features a more powerful STM32F205 cortex M3 micro-controller, as well as more I/Os than ESP8266. Specifications for EMW3162 Wi-Fi module: MCU – STM32F2 Cortex M3 MCU @ 120 MHz with 128KB RAM, 1MB flashOn Wi-Fi connectivity 802.11b, 802.11g, 802.11n (single stream) on channel 1-14 @ 2.4GHz WEP, WPA/WPA2 PSK/Enterprise (hardware encryption) Transmit power: 18.5dBm@11b; 15.5dBm@11g; 14.5dBm@11n MIN Receiver Sensitivity: -96 dBm Max Data rate: 11Mbps@11b; 54Mbps@11g; 72Mbps@11n HT20 Wi-Fi modes: Station, Soft AP and Wi-Fi direct Advanced 1×1 802.11n features: Full/Half Guard Interval, Frame Aggregation, Space Time Block Coding (STBC), Low Density Parity Check (LDPC) Encoding […]

Radxa Rock 2 Square is a Rockchip RK3288 Development Board for Hobbyists

When Radxa Rock 2 was first unveiled, it became clear it was not aimed at the hobbyist market, as it includes lot of features such as SATA, 3G modem, dual Gigabit Ethernet, up to 4GB memory and so on, and is likely to cost a few hundred dollars. The company is now working a cheaper baseboard called Radxa Rock 2 Square leveraging the same Radxa Rock 2 SoM used with the full-featured baseboard (now also called Radxa Rock 2 Full), but with less features and at price point that should be more affordable to individuals. Preliminary Rock 2 square specifications (derived from picture above): Processor/Memory/Storage – Via Rock2 SoM including Rockchip RK3288 quad core Cortex A17 processor, 2 to 4 GB RAM, and 16GB eMMC. External Storage – SATA and micro SD slot Video Output – HDMI, LVDS connector Audio I/O – HDMI, headphone jack, built-in microphone, and optical S/PDIF […]

Cubieboard4 Benchmarks in Android

Last time I tried running benchmarks in an Allwinner A80 board (A80 OptimusBoard), it either rebooted during the benchmark, or had fairly disappointing results for example for USB storage. I documented my findings in a post entitled “Current Performance and Stability Issues on AllWinner A80 OptimusBoard Development Board” which was written in October 2014. But a few months have passed, and since Cubieboard4 is another hardware platform, so I was interested in running benchmarks including storage and networking performance testing on the new board to see if any progress was made. Cubieboard4 Android Benchmarks – Antutu, Vellamo, and 3DMarks Manufacturers can add the key ro.sys.hiritsu to build.prop in order to artificially inflate their Antutu scores with Allwinner A80 processor. So before running Antutu, I checked /system/build.prop in the firmware, and found out no trace of this variable, which can only be good for CubieTech reputation. CC-A80 board, the other name […]
