The Flip&Click Board™ from MikroE has just been released. It was announced at Rome Maker Fair to wide acclaim. It is basically an Arduino board based on the same 32-bit AT91SAM3X8E CPU with an ARM Cortex M3 architecture with the usual Arduino expansion capabilities (The Blue Side).
However, the back of the board (The White Side) of the Flip n Click Board™ is fitted with four MikroBus sockets. This allows up to four Click Boards™ to be fitted and run simultaneously, significantly enhancing the Arduino's expansion capabilities.
Over 1200 Click Boards™ are now available from MikroElektronika, and stocked by The Debug Store, more than any other reseller!
