Prototyping modules are an ideal way to make it easier to build your own circuits for the Raspberry Pi, Arduino Uno or other microcontrollers. The small boards can be used to fix the circuits in place. Some modules have a plug-in adapter that can be used to connect all GPIO, I2C and supply lines to the board. Discover a wide selection of prototyping modules in different sizes and for a variety of applications from renowned manufacturers such as Adafruit, Seeed Studio and Sparkfun.
