Firefly introduces FireBLE Bluetooth Low Energy Board

So just as today I wrote about XBAND BLE Sensor board, the makers of Firefly-RK3288 also announced their own Bluetooth Low Energy board aptly named FireBLE, and also integrating a 6-axis gyroscope and accelerometer, but instead of being based on Nordic or Cypress, the company went with an NXP BLE chip. FireBLE board specifications: SoC – NXP QN9021 ARM Cortex M0 MCU @ 32MHz with 94KB ROM (protocol stack), 64 KB SRAM, 128KB flash Bluetooth – BT 4.0 single mode. Central and peripheral mode with up to 8 simultaneous connections. Sensors MPU-6050 3-axis gyroscope and 3-axis accelerometer with an on-board Digital Motion Processor (DMP) capable of processing 9-axis motion fusion algorithms. Battery and temperature sensor USB – micro USB port for power and programming Expansion – 3 expansion headers with access to SPI, UART, I2C, GPIO, and PWM, as well as OLED display interface. Debugging – JTAG, support SWD online […]

Allwinner CedarX Media Codec Library GPL/LGPL Compliance Update

Last month, I wrote about potential open source licenses and VP6 copyright infringement by Allwinner with their CedarX media codec library, and then since there’s been a few developments. First, Allwinner sent me an email saying they’ve now updated Cedarx library and referring my previous article. Here’s an extract: Here, I have some update of the Allwinner’s open-source status. We have done a lot of discussion with the developers from the linux-sunxi communication about the software license of CedarX. For each question or requirement asked by the developers, Allwinner has identify and try to give the best solution. Now, we believe Allwinner’s CedarX license is fully compliant and resolves concerns from the community. And you can take the announcement https://www.mail-archive.com/[email protected]/msg10597.html as a reference. Allwinner is always supporting the open-source, and try to do better and better. You can see some update on the github https://github.com/allwinner-zh, and some feedback from developers: […]

XBAND is a Tiny $10 Bluetooth Low Energy Sensor Module (Crowdfunding)

ZX Tek‘s XBAND is a board about half the size of a micro SD that comes with a Bluetooth LE radio and a 6-axis MPU6500 motion sensor that can be integrated into wearables and IoT applications such as a remote controlled robot with a camera., a wireless smart light-bulb, and iBeacon device and so on. There seems to be two versions of the module XBAND 061-N51822 and XBAND 1018-CY8C4247 with the following specifications: SoC (one or the other) Nordic Semiconductor nRF51822 ARM Cortex M0 MCU @ 16 MHz with 256KB Flash, 16KB RAM, and Bluetooth Low Energy support Cypress PSoC4 BLE core ARM Cortex M0 MCU @ 48 MHz with 128KB flash, 16KB RAM, and Bleutooth Low Energy support Bluetooth – 4.0/4.1 with high gain ceramic chip antenna Sensors – On-board 6-axis MPU6500 motion sensor + an extra configurable sensor (not idea what that is…). Connectors – Board-to-board connectors with […]

How to Install Ubuntu 14.04 on Acer Aspire E5 Laptop

I’ve been owning an Acer Aspire One D255E netbook with a 10″ display, an Intel Atom N455 processor and 1GB RAM that served me well during my travels, but as I’ve become older and less patient, I felt I needed to upgrade it. I planned to spend around 10,000 Baht (~$300), wanted a 14″ display, one of the low power CPU such as Intel Bay Trail-M or AMD Mullins / Beema processors, at least 500GB storage, 4GB RAM, and the ability to install Ubuntu. Finally, after going through several products at my local shop, I had to chose between Acer Aspire E5-411-P3CL with a 7.5W TDP Intel Atom N3540 and Acer Aspire E5-421G-45L0 with a 15W TDP AMD A4-6210 processor that both sell for 11,900 Baht ($365). Despite my preference for processor with lower TDP, I still went with the AMD system, since the performance is a little better, the […]

Acer Shamelessly Sells Aspire E5 Laptops with a Crippled UEFI Setup Utility

Yesterday, I bought an Acer Aspire E5-421G-45L0 laptop powered by AMD A4-6210 “Beema” processor and after some effort I managed to install Ubuntu 14.04 and make it mostly work, but more on that later. I also planned to copy a 64-bit OS VirtualBox virtual machine from another PC to this PC, but I quickly realized I could only select 32-bit operating systems, so my 64-bit image could not boot. Virtualization extension are required for 64-bit support in VirtualBox, and I had not checked whether AMD A4-6210 supported these before purchase. Amazingly, I could not find that information on AMD’s very own website, but CPU Boss reports A4-6210 does indeed support AMD-V virtualization. All good, so I must be just a question of enabling it in the “BIOS”. So I rebooted the laptop, and pressed F2 to enter InsydeH20 Setup Utility. There are few options with only Information, Main, Security, Boot, […]

Asus C201 Chromebook to be Powered by Rockchip RK3288 Processor

If you’ve been following this blog, you should know that Rockchip is working with Google on Chrome OS, so it was just a matter of time before a Rockchip powered Chromebook or Chromebox sees the light of the day. The first Rockchip RK3288 chromebook might end up being Asus C201 Chromebook with apparently a custom version of the Cortex A17 processor dubbed Rk3288-C, as OMG Chrome found out in Troxell’s 2015 brochure for K-12 education. So far we only know a few details about the specifications: SoC – Rockchip RK3288-C quad core Cortex A17 processor @ up to 1.8GHz System Memory – 2 to 4 GB DDR3 Storage – 16GB eMMC Display – 11.6″ display with 1366×768 resolution Webcam – VGA resolution The exact model name should be C201PA. Rockchip RK3288 should provide performance quite similar, and in some cases even better, to Intel Atom Z3735F, except possible when it comes […]
