Atmel SAMA5D3 Xplained Board Unboxing and Quick Start Guide

Atmel SAMA5D3 Xplained is an evaluation board running Linux powered by SAMA5D36 ARM Cortex A5 micro-processor with 256 MB DDR2, 256 MB flash, two Ethernet ports, 3 USB connectors, and more. This embedded board targets industrial automation, networks, robotics, control panels and wearable applications. The only video output is an LCD connector so it is reserved for headless or flat panel based applications. You can check full specs on my Atmel SAMA5D3 Xplained announcement post. The company kindly sent me a sample, so that I can share my experience with the board. I’ll first post some unboxing pictures, show how to get started with the pre-installed image, and build my own Linux image. The board can be purchased for $79 from Atmel e-Store, as well as several distributors (P/N: ATSAMA5D3-XPLD). Atmel SAMA5D3 Xplained Unboxing I’ve been sent the board via DHL in the following package, which gives a short desscription […]

Texas Instruments Tiva C Series TM4C1294 Connected Launchpad Sells for $20

There are now many ultra low cost MCU development kit selling for $15 to $25 such as STMicro Discovery Board, but for this price, they’ll usually just feature the MCU, a micro USB, pin header, maybe and maybe some sensors, and they usually lack any form of connectivity, at least without extra hardware. With Tiva C Series TM4C129 Connect Launchpad, Texas Instruments brings a board that can be used for IoT application out of the box thanks to the addition of an Ethernet port. The board sells for just $19.99, which means you could easily make something like a connected 4-relay control system for about $25. Connected LaunchPad evaluation kit specifications: MCU – Texas Instruents TM4C1294NCPDT ARM Cortex-M4 @ 120MHz with floating point, 1MB Flash, 256KB SRAM, 6KB EEPROM, Integrated 10/100 Ethernet MAC+PHY, data protection hardware, 8x 32-bit timers, dual 12-bit 2MSPS ADCs, motion control PWMs, USB H/D/O, and many […]

BroadLink SP2 Wi-Fi Smart Socket for iOS and Android Adds Support for Energy Monitoring, Motion Sensing

Broadlink SP1, a low cost Wi-Fi smart socket released last year, allows you to control your electric appliance with your mobile device running iOS or Android. You could turn it on or off, set timers, and so on. An updated model is now available, Broadlink SP2, that adds energy monitoring to the features found in the previous model, to track your historic and live power consumption on your smartphone or tablet, as well as a motion sensor to automatically turn off the lights, for instance, if you are away (Auto Home / Auto Away feature). The hardware specifications are very similar to SP1 except it’s using a case made of polycarbonate plastic instead of ABS, and the device is a bit bigger: Material – PC Wi-Fi – 802.11 b/g/n Power Plug – Three flat-pin plug (Australia type) Voltage – 100~265V @ 50-60 Hz Output Current – 10A Output Power – […]

Alps Electric Magnetic Field Sensor Measures 1.15 x 1.15 mm, Software Algo Adds Gyroscope Function

I’m really impressed with the recent miniaturization of boards and components. Back in the days (in 2012), many people were amazed at the credit card size of the Raspberry Pi ARM Linux computer. Since then, we’ve seen many other ARM Linux board with similar or even smaller sizes, and on a broader scope, many smaller and smaller hardware and components: Olimex launched OLIMEXINO-85S Arduino compatible board about the size of a micro SD Card, eConais unveiled WiSmart EC19D Wi-Fi module measuring 8×8 mm, Freescale recently announced Kinetis KL03 Cortex M0+ MCU measuring 1.6 x 2.0 mm in its smallest package, etc… Today, I’ve come across another tiny chip, the world smallest magnetic field sensor by Alps Electric that measures only 1.15 x 1.15 x 0.56 mm. Height does matter too. It’s about 60% smaller than previous product by the company, but only slightly smaller than Asahi Kasei Microdevices’ AK09911C which measures 1.2 x […]
