$35 Tessel 2 IoT Board Features Atmel SAMD21 MCU and Mediatek MT7620n WiSoC

Tessel is a Wi-Fi IoT board based on NXP LPC1830 Cortex M3 MCU and Texas Instruments CC3000 modules, that’s designed to bring embedded development to web programmers with a system that can be programmed with JavaScript and Node.js.  At the time of the crowdfunding campaign in 2013, the board was available with external modules (Relays, sensors, Bluetooth LE…) for $100 and up, but now Technical Machine, the company behind the project, has announced Tessel 2 combining Atmel SAMD21 Cortex M0+ to control I/O and Mediatek MT7260n for Wi-Fi connectivity, still programmable with JavaScript ot Node.js. Tessel 2 specifications: MCU – Atmel SAMD21G14A-MU Cortex M0+ MCU @ 48MHz with 16KB SRAM and 2KB Flash SoC – Mediatek MT7260n MIPS24KEc Wi-Fi SoC @ 580 MHz System Memory – 64MB DDR2 Storage – 32MB flash for firmware (OpenWRT) Connectivity – 10/100M Ethernet, and Wi-Fi 802.11 b/g/n with dual PCB antennas USB – 2x USB 2.0 host ports + 1x micro USB port for …

Tessel ARM Cortex-M3 MCU Board Brings Hardware Hacking to Web Developers with JavaScript and Node.js

People who are proficient with JavaScript or web technologies may not be completely comfortable with programming MCU in assembler and/or C programming language. Node.js, written in JavaScript, seems to be quite popular this days for diverse projects, but technical.io has decided to design a board called Tessel, powered by a Cortex M3 MCU. that can be fully programmed with JavaScript/Node.js. Tessel hardware specifications: MCU – NXP LPC1830 ARM Cortex-M3 @ 180mhz System Memory – 32MB SDRAM Storage – 32MB Flash Connectivity – Wi-Fi via TI CC3000 Expansion – 16-pin GPIO bank for prototyping Power – Micro USB or battery The board is said to be compatible with 1000’s of Node.js modules from NPM, can be programmed via USB or Wi-Fi using your own IDE, and support Tessel modules, as well as Arduino Shields. There are two (price) classes for Tessel modules: Class A: Relay — turn devices on and off (up to 5 amps) Temperature/Humidity sensor — get information about the …
