IoT Wi-Fi Modules Comparison Table – ESP8266 vs CC3000 vs RN131 vs HDG204

We now have several options to add WiFi to IoT / embedded projects at relatively low cost, and ESP8266 based solutions clearly wins on costs, but are there some advantages to other higher priced modules? To help us find out, Mike Barela has put up a comparison table with some Wi-FI modules based on Espressif ESP8266, Texas Instruments CC3000, Microchip RN131, and H&D Wireless HDG204 processors. Note 1 – Also comes in Arduino Shield size with SD card slot for $39.95 Note 2 & 3 – Adafruit and Sparkfun sell tested units with AT Firmware for $6.95. lower prices are available on eBay, but quality may vary. Note 4 – Currents are probably somewhat higher than stock ESP-12 due to onboard LED and regulator. The comparison is not exhaustive, but it still appears to show ESP8266 solutions support most features than pricer competing modules. There are however case where competing […]

Tronsmart Draco H3 TV Stick Firmware and SDK Released

Tronsmart Draco H3 is a low cost HDMI TV stick powered by Allwinner H3 quad core processor. At $35, the device costs about $5 more than Amlogic S805 based sticks like MK808B Plus with about the same specs (quad core Cortex A7/A5, 1GB RAM, 8GB flash, HDMI out..), but with the added benefit of 4K @ 30Hz support. Tronsmart has now released some firmware files as well as Linux kernel and an Android SDK. Two firmware files have been released: Tronsmart_Draco_H3_720p_Kernel_20150526.zip – Firmware with 1280×720 framebuffer for better performance Tronsmart_Draco_H3_1080p_Kernel_20150526.zip – Firmware with 1920×1080 framebuffer for higher resolution Please note that the resolution will only affect the user interface, and when you play videos you should get the resolution selected in Android settings. So if you play a 4K videos it will truly show as a 4K video on your TV, even though the user interface is only 720p, at […]

Allwinner R8 Module Datasheet and Price. Is the $9 C.H.I.P Computer Selling at a Loss?

Allwinner R8 Cortex A8 processor, very similar to Allwinner A13, but optimized for IoT applications, was first unveiled via the $9 C.H.I.P computer crowdfunding campaign, but at the time we did not have that many technical details. However, Olimex had already made several Allwinner boards in the past, such as A20-OLinuXino-LIME, so they decided to investigate if they too could use Allwinner R8 processor, or rather Allwinner R8 Module (R8M) with R8 SoC, 4/8GB NAND Flash and 512 MB RAM. So they managed to get R8M datasheet, and got quoted $4.8 for Allwinner R8 and $16 for Allwinner R8M with 512 MB RAM and 8GB NAND Flash for 5,000 unit orders. Wait… If R8M module is $16, how can C.H.I.P sell it for $9? One difference is that C.H.I.P module only has 4GB NAND flash, but the module quoted to Olimex appears to come with 8GB flash, but it’s not […]

Dell Inspiron Micro Desktop with Intel Celeron J1800 or Pentium J2900 Starts at $180

We’ve already seen Chinese mini PCs based on Intel Bay Trail-D processors for less than $200, even with a 500 GB HDD as found in VX2 mini PC, but if you’d like to buy from a more established brand, Dell has launched two models of Inspiron 3050 Micro Desktop with Intel Celeron J1800 (dual core) and Pentium J2900 (quad core) selling respectively for $179.99 and $229.99 direct from Dell US, and they also have built-in Gigabit Ethernet and 802.11ac that you may not always find in the cheaper Chinese models.

Linaro 15.05 Release with Linux 4.1 and Android 5.1

Linaro 15.04 has been released with Linux 4.1-rc4, Linux 3.10.79 and 3.14.42 (LSK), and Android 5.1_r3. The Ubuntu image is now based on Vivid instead of Utopic. Android and Debian builds/images have been released for Hikey’s 96boards, Ubuntu Vivid and Android builds have been setup for Qualcomm’s Dragonboard 410c. A new platform, Socionext M8M, has also show in Linaro changelog. I could not find details about M8M, but Socionext is a “new company that designs, develops and delivers System-on-Chip products” and focuses on “imaging, networking and other dynamic technologies”. Their latest press release mentions a 4K media processor with build-in HDMI 2.0 Tx and Rx, so maybe M8M is based on that processor, but I can’t know for sure as they have several chips. Highlights of this release: Linux Linaro 4.1-rc4-2015.05 GATOR updated to version 5.21.1 updated integration-linaro-vexpress64 topic by ARM LT: PCI support added – for Juno r1. Linaro […]

ESP8266 SDK 1.1.0 is Now Released Under an MIT License

ESP8266 is the now famous dirt-cheap Wi-Fi SoC used for IoT applications. It can be used by hobbyists and companies alike. But for the later, there was a licensing issue as Espressif ESP8266 SDK was initially released under the GPLv3 license. GPL code is great and lots of open source projects are released under the most common open source license. But since proprietary, closed source software has still its place in the market place, some other more permissive licenses such as LGPL are used for library, and Android for example has an Apache License 2.0. So previously, if you developed an application using ESP8266 SDK, you’re code would have to be GPL too, since the license is viral. It would also cause issues if you had released your application under an Apache or MIT license. But now, all is well, as Espressif released ESP8266 SDK 1.10 under an MIT license, […]
