Ranked in these QuestionsQuestion Ranking
Pro NodeJS support out of the box
Out of the box it supports Node 4.x LTS and doesn't require any setup to use it.
Pro Co-processor system
Runs Linux and user application code on a 580MHz Mediatek router-on-a-chip, with an asynchronous 48MHz SAMD21 coprocessor for GPIO, ADC, I2C, SPI, PWM and UART programming
Pro Programmable via USB or Wifi
Pro Easy to get started with
The Tessel 2's "Getting Started" experience requires little more than installing Node.js and a single package (the CLI) via npm. Complete walkthroughs for Linux, Mac and Windows are available and up-to-date
Con Very little memory
64 megabytes of RAM. This places it more in line with an Arduino style board than a SBC on the level of Raspberry Pi.
