Key features of RFDuino board: MCU – Nordic nRF51822 Cortex M0 @ 16 MHz Memory –  16 KB on-chip SRAM Storage – 256 KB on-chip Flash Connectivity – Bluetooth 4.0 Low Energy built in MCU GPIO – 7 pin software configurable as digital IO, analog ADC, SPI, I2C, UART and PWM.  The company currently offers several stackable shields for RFDuino including battery shields (1x AAA, 2x AAA, and CR2032 coin battery), a servo shield, a USB shield, a prototype shield […]

Thingsquare Mist – Open Source Firmware for The Internet of Things

Thingsquare recently released the source code for the Thingsquare Mist firmware, an ultra lightweight router software (<4 kB memory) for the Internet of Things based on open Internet standards such as IPv6, RPL (Routing Protocol for Lossy networks), and 6lowpan. Thingsquare Mist allows to connect battery-powered wireless micro-controllers to the Internet, and is currently used in applications such as smart light bulbs, connected home appliances, and connected cities. The IPv6 mesh network is composted of nodes with a low power radio that communicate with the Mist router (Green), which in turn connect to the Internet and Thingsquare Cloud backend (Thingsquare Haven) to store the data, and/or receive control commands via Ethernet or Wi-Fi. The end users can then use an App to monitor, and/or control the devices remotely. Thingsquare Mist uses IETF RPL IPv6 mesh routing protocol (pronounced “ripple”) for IPv6 nodes communications. Thingsquare Mist runs on several low-power wireless […]

How to Root Rockchip RK3188 mini PCs

CloudnetGo CR9 was the first Rockchip RK3188 mini PC I had ever seen reported, but since then others apparently based on the same board have started to show up including Tronsmart T428, Rikomagic MK802 IV, as well as Ugoos UG802B, UG007B and MK809 III. We’ll get a lot of choices, but most of time the firmware does not provide root access. I noticed AndroidPC.es published instructions to root those device in Spanish yesterday, but today, Geekbuying rooted the Ugoos devices with the same method used for RK3188 Tablets. You have to follow those 5 simple steps: Make sure USB Debugging is enabled on your mini PC (Settings -> Developer Options) Connect your RK3188 mini PC to a Windows PC via the USB port. Your PC should detect a new device, and try to install the driver. You can download the driver at https://www.dropbox.com/s/uqisjj4hqftlaxa/GEEKBUYING_Rockchip_Batch_Tool_v1.6.rar (password: GEEKBUYING.COM) After having installed the driver, download […]

MK808 mini PC gets Android 4.2.2 Beta Firmware

Last week, Geekbuying announced the first release of Android 4.2.2 for MK808, with support for MK808B coming soon. They warn users that it’s still beta since this is the first time Android 4.2 is available on Rockchip RK3066 mini PC, however I could not find user’s complains in the comments section, but at least one users in ARMTvTech is disappointed by this release. You’ll find three download links: Android 4.2.2 for MK808 (dropbox) – Currently unavailable due to heavy traffic Android 4.2.2 for MK808 rooted (Gdrive) – Same version as above but rooted by deadhp1 RKBatchTool  1.5 (dropbox)- Windows tool to perform the upgrade. Currently unavailable but there are alternate links. Once you get the files, you can follow the instructions showing how to upgrade MK808 firmware, or watch the video showing the upgrade process. MK808 is another device I don’t own, so I haven’t been able to try it […]
