Arduino TRE Powered by TI Sitara AM335x Enters Beta with 50 Developer Boards Available for Purchase

Most official Arduino boards are based on Atmel AVR MCUs that allow hobbyists to control GPIOs, or low level interfaces, which is fine for applications that do not require much processing power. In the last couple of years however, the Arduino team has gone up the processor scale, first with Arduino Due with an ARM Cortex M3, then Arduino Yun with a MIPS processor running OpenWRT, and there latest board Arduino TRE features a Texas Instruments Sitara AM3359 AM3358 processor capable of running any Linux distributions supporting ARM. The board was announced last year, and Arduino has now launched a beta program where developers can purchase one of the 50 “Arduino TRE Developer Edition” boards for 149 Euros + VAT. Arduino TRE specifications (Parts related to TI Sitara highlighted in green): SoC – Texas Instrument Sitara AM3359AZCZ100 AM3358 (See comments) ARM Cortex A8 processor @ 1 GHz with PowerVR SGX530 […]

How to Make a $15 Web Server for IoT Applications

Arduino_Leonardo_Ethernet_ENC28J60_Assembled

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 […]
