Bricklets
Tinkerforge Bricklets are compact modules designed to extend the features of Tinkerforge Bricks, adding sensors, I/O, Human Machine Interface (HMI), and more. Unlike Bricks, Bricklets have no fixed size. Each Bricklet is the minimum possible size. Each Brick has up to four connectors for Bricklets. Bricklets can be controlled over the USB connection of the connected Brick. Bricklets are not equipped with processors, but each one possesses its own Application Programming Interface (API). From a programming perspective, they are handled as independent modules. On startup, a Brick detects connected Bricklets. The Bricklet plugins, stored in the EEPROM of the Bricklet, are loaded into the flash of the Brick. This adds new functions to the Brick that can then be used from the PC.
