MCU Energy Efficiency Benchmark – Freescale KL02, Microchip PIC24, TI MSP430, and STMicro STM32L

Freescale has recently uploaded a video comparison the energy efficiency of several micro-controllers: Freescale Kinetis KL02, Texas Instruments MSP430, STMicro STM32L, and  Microchip PIC24. Since it’s a Freescale video, we already know the winner, but the test they performed it still interesting, and it shows drastic performance differences between architectures. The used the following exact MCU for testing: Freescale MKL02Z32CAF4R – Cortex M0+ @ 48 MHz STMicro STM32L151RBT6 – Cortex M3 @ 32 MHz Microchip PIC24FJ128GA308 – 16-bit MCU @ 32 MHz Texas Instruments MSP430F5529 – 16-bit MCU @ 25 MHz Freescale did not really select tough competition such as NXP LPC800 Cortex M0+, but instead a Cortex M3 MCU, and older 16-bit MCUs. I don’t know if Microchip has a new generation of ultra low power 16-bit MCUs , but Texas Instruments, for example, launched MSP430 Wolverine MCUs at the end of last year. So this comparison may not be […]

Ugoos UM2 Android TV Stick Features Two Full Size USB Ports

Most Android HDMI TV dongles come with only one full size USB port, as well as some micro or mini USB ports. The user then has to use an external USB hub if he or she wants to connect standard USB keyboard and mouse, and ends up with some kind of cable mess. Ugoos UM2 mini PC does not have this issue as it comes with 2 full size USB ports. The rest of the specifications are standard for a quad core HDMI TV Stick: SoC – Rockchip RK3188 Quad core Cortex-A9 +  Mali 400 MP4 GPU System Memory – 2GB DDR3 Storage – 8GB NAND Flash (Option for 16G/32G) + micro SD card slot (Up to 32GB) Connectivity – WiFi 802.11 b/g/n, Bluetooth (Version 4.0 TBC) Video Output – HDMI 1.3 Male USB – 2x USB Host ports + 1x micro USB port for power Power Supply – 5V/2A Dimension – […]

How to Buy an Arduino Leonardo (Clone) Kit for Less than $20

Borderless Electronics Indiegogo campaign for their $9 electronics kit with an Arduino Leonardo clone went so well that the owner of the campaign decided to limit the total number of boards to 15,000, and basically stop the campaign early to avoid production delays. For $12 ($9 + shipping), you could get a full kit with: Arduino Leonardo clone A mini breadboard with 10 Jumper wires A plug for a 9V battery A few components: 6 LEDs, 10x 330 Ohm resistors, 10x 1 KOhm resistors, 3x push buttons, 2 NPN transistors, 5 diodes, a light sensor, and a sound buzzer A micro USB to USB cable Although they may start a new one campaign in a few months, the campaign is over, and you can’t get this cheap Arduino kit anymore. But one of my reader (onebir) let me know that for less than $20, you can  get an Arduino Leonardo […]

CheapCast Chromecast Emulator for Android (Beta) is Available for Download

Yesterday, I wrote developers were working on making any media App and any Android device compatible with Chromecast. Sebastian Mauer has taken care of the latter, by publishing CheapCast (Beta) in Google Play. Several people have been trying it successfully, including in iMito MX1 mini PC. I’ve been less lucky. I’ve tried it by running YouTube App in Zopo ZP900S smartphone (Android 4.0.4) with 4 devices: Tronsmart T428 – “Works” but the video won’t start playing. (Bug reported in Github’s issue tracker) [Update: It now works with the latest version in Google Play]. MK908 – Refused to install anything in Google Play today… (Older Android 4.1 firmware) Wandboard Quad – “Works” but the video won’t start playing. CX-01 – CheapCast will crash when playing video I can’t really play YouTube videos over 360p without buffering here, so the reason the video won’t start in T428 or Wandboard Quad might be […]

$275 HackRF Open Source Software Defined Radio (SDR) Platform

HackRF is an open source hardware project to build a Software Defined Radio (SDR) supporting a frequency range between 30 MHz and 6GHz in both directions (Tx and Rx, half-duplex) with a maximum bandwidth of 20MHz. Jawbreaker (shown below) is a beta hardware that has been tested by several developers and beta testers, and applications such as Digital Audio Broadcasting (DAB), Bluetooth monitoring, spectrum sensing, wireless microphones, AIS, FM radio, etc.. have already been ported to the platform. In order to lower the cost of the hardware, Michael Ossmann has launched a Kickstarter campaign to fund mass production. There seems to be many SDR enthusiasts as the campaign has already reached its funding target ($80,000) and received for over $300,000 in ledges. What is Software Defined Radio (SDR) and What Can it Be Used for? Before providing details about the hardware and software, it may be useful to provide some […]
