Arduino compatible Attiny85 Digispark board

This Seeeduino XIAO is the smallest Arduino compatible plate of the Seeeduino family. It is an Arduino microcontroller, integrated with the SAMD21 microchip. Despite its tiny size, it has enough interfaces for many applications.

This development board is specially designed to work with the Bare conductive Electric Paint, which makes it possible to convert touch into sound, light or any action you want. With its 12 capacitive electrodes you can create a multitude of innovative projects and scenes, combining them with the Electric Paint. It has an MP3 decoder and a MIDI synthesizer, as well as a 3.5 mm audio connector and support for micoSD cards (includes 128 MB microSD). It is based on the Arduino Leonardo and uses the ATmega32U4, which works at 16MHz and 5V. 

Do projects on touch and interactive proximity detection in a different and simple way thanks to this Touch Board.

It's a tiny board, programmable from the Arduino IDE, that hides enormous potential. The Teensy 4.0 is equipped with a 32-bit ARM Cortex-M7 processor at a blazingly fast 600 MHz. The use of the NXP iMXRT1062 chip makes the Teensy 4.0 the fastest microcontroller on the market at launch.

BeagleBone Green (102010027) is a powerful single board computer (SBC). The main change is the replacement of the HDMI interface with 2 Grove connectors. Grove is a great invention by Seeed, it is a standardised modular connector prototyping system that allows for solder- and cable-free applications. It uses the open source hardware design BeagleBone.
