UDOO Neo Combines Arduino, Raspberry Pi, Wi-Fi, Bluetooth and Sensors into a Single $49 Board (Crowdfunding)

UDOO Neo was unveiled last February as the first hobbyist board features Freecale i.MX6 Solox Cortex A9 + Cortex M4 processor. I was expecting UDOO to design support board since their earlier UDOO board combined Freescale i.MX6 processor with an Atmel MCU, and the new processor allowed for integrating the same functionality into a single chip. The board is now on Kickstarter where you can pick UDOO Neo Basic for $49 (Early bird is $35), or UDOO Neo for $59 (Early bird was $45) adding an Ethernet port, some sensors, and 1GB RAM, instead of 512 MB for the Basic version. But both versions of the board basically share the same specifications: SoC – Freescale i.MX 6SoloX ARM Cortex-A9 core @ 1GHz with 2D/3D GPU and ARM Cortex-M4 Core @ 166 MHz System Memory – 512MB (Basic) or 1GB DDR3 Storage – micro SD slot, 8-bit SDIO interface (on expansion headers) […]

Onion Omega is an Atheros AR9331 Wi-Fi Module Supporting Various Docks and Add-on Boards (Crowdfunding)

There are so many inexpensive Wi-Fi modules running Linux that it would be easy to discard Onion Omega as yet another Wi-Fi module based on Atheros AR9331 WiSoC. However, the developers have tried to bring some added value by making programming easier for web developers, integrating it with a cloud platform (free for non-commercial use), and providing basicor Arduino dock, and add-on boards for Ethernet, OLED, Relay… to make building hardware projects easier too. Let’s go through the hardware first, starting with the module specifications: SoC – Atheros AR9331 400MHZ MIPS 24K System Memory – 64MB DDR2 400MHz Storage – 16MB Flash Connectivity – 10/100 Mbps Ethernet + 802.11b/g/n Wi-Fi up to 150Mbps with PCB antenna w/ uFL connector I/Os – 18 GPIOs USB – 1x USB 2.0 Power Supply – 3.3V; Typ. consumption: 0.6W Dimensions – 28.2mm x 52mm (1.1″ x 2.0″) Since this type of module is not […]

Wi-Fi SD Card Adapter for micro SD Cards Sells for $15 and Up

Wi-Fi SD cards are mostly used with camera in order to wirelessly transfer photos or/and videos to your computer or mobile device without having to take out the card or transfer them via a micro USB cable. I first discovered this type of card with Toshiba FlashAir in 2011, but now EyeFi seems to be the most popular brand, and comes in different sizes with the 8GB Wi-FI SD card selling for $44 on Amazon US. There are cheaper alternatives with some Wi-Fi SD card adapters accepting micro SD card selling for about $15 and up on Aliexpress or Buyincoins, and DX calls it CY EP-027, but sells it for $23. It does not come with storage but since a 8GB class 10 SD card now costs about $8, it’s still nearly 50% cheaper compared to the 8GB EyeFi SD card. Some features of the card: Max micro SD card […]
