How to Make a $15 Web Server for IoT Applications


If you have an embedded project that requires some GPIOs, and Ethernet connectivity, you now have a few choices of low cost low boards such as the Raspberry Pi with Broadcom ARM11 SoC for $35 + shipping,  Texas Instruments Connected LaunchPad with an ARM Cortex M4 MCU for $20 including shipping, and today I’ve given a try at a solution to run an HTTP server with an Arduino Leonardo clone connected to ENC28J60 Ethernet module that together cost about $15 including shipping. This Ethernet module has been around for a while and is well supported, I just never took the time to give it a try before. I’ve purchased ENC28J60 module on eBay for $3.46 and connected it via SPI to an Arduino Leonardo clone I acquired as part of a kit via Indiegogo for $12. The kit is not available for purchase outside the crowdfunding campaign, but you can […]

GOsingGO GSG-TB06 Android TV Stick Features an Ethernet Port

There’s a plethora of Android HDMI TV dongles, but all of them only provide Wi-Fi connectivity, and if you need better network performance you need to add Ethernet via an USB to Ethernet dongle. There’s now another solution, that may not be very new, with GOsingGO GSG-TB06 a mini PC based on AllWinner A10 that includes an Ethernet Port. Here are the specifications of the device: SoC – Allwinners A10 @  1.0GHz System Memory – 1GB RAM Storage -4 to 32 GB flash + micro SD card slot Video output – HDMI & AV USB – 1x USB 2.0, 1x micro USB for power Connectivity – Ethernet (RJ45) + Wi-Fi 802.11 b/g/n (AR6103) Dimensions – 105L x 37W x 15.6Hmm The device comes with a USB power adapter, an RCA (AV) cable, and a user’s manual. The manufacturer says it’s running Android 4.1. The specs are not that great, but […]

IEEE Updates 802.11 Standard to Support 600Mb/s Wi-Fi and Approves 802.1aq Standard for Large Ethernet Networks

IEEE has recently announced a standard update for WiFi (802.11-2012) which adds support for 3.7 GHz bands, 600Mb/s throughput and mesh networking among other things, and approved 802.1aq Shortest Path Bridging standard, which will streamline the creation and management of large Local and Metropolitan Area networks by using the next-generation VLANs. IEEE Wi-Fi 802.11-2012 Standard IEEE 802.11-2012 is the 4th revision of the Wi-Fi standard. It has been expanded by supporting faster and more secure devices, while offering improved Quality of Service and cellular network hand-off. Key amendments to the standard: IEEE 802.11n now defines MAC and PHY modifications to enable throughput up to a maximum of 600Mb/s Direct-link setup “Fast roam” Radio resource measurement Operation in the 3650-3700MHz band Vehicular environments, mesh networking, security, broadcast/multicast and unicast data delivery Interworking with external networks and network management. IEEE 802.11 is available for purchase for $5 at the IEEE Standards Store. […]
