Tessel - “Build your product faster. Tessel 2 is a development platform you can embed in a product. Build fast with Node.js/io.js, then optimize the hardware and build thousands”.
“Note that the Camera Module will not work with Tessel 2. For camera on Tessel 2, use the USB Camera Module”.
The camera is recording the photos mirror-inverted, as the original CCD hardware does. With usual cams, the correction ( = mirroring back to a “normal” photo ) is done by internal camera firmware.
“USB Camera” - “USB Camera Module for Tessel 2. Camera, webcam, video, audio, and still images all wrapped up and supported in one. Should work with any USB webcam and/or USB speakers”.
As of 2016-02:
Tessel1 is incompatible to “NodeJS 4” and so requires to install NodeJS 0.12.10”.
The “relayr Python Library” can't be installed on Windows. The installation “pip install relayr” on Python 2.7 aborts by the error message “Pexpect is intened for UNIX-like operating systems” .
