Interface breakout boards
OpenPressure combines an ADS1220 24-bit ADC and a SAMD21 microcontroller to make a complete 24-bit, high precision pressure and temperature sensor interface.
This incredibly small stereo amplifier is surprisingly powerful - able to deliver 2 x 2.1W channels into 4 ohm impedance speakers (@ 10% THD).
LP55231 LED Breakout is an Led controller that controls a series of RGB'S and is best suited for variable intensity and colour mixing applications.
Sparkfun Load Cell Amplifier breakout board is precise and accurate ,reads data from load cells to measure weight.
Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakouts to control up to 992 PWM outputs (which we would really like to see since it would be glorious)
HDMI Plug Breakout Board is a light weight ,less expensive breakout board.
ProtoPi T with USB Serial Access is an add-on to the breadboard as it allows you to play with all the GPIO pins
Proto Pi T bridges the gap between the Raspberry Pi3 and the breadboard.
PROTOCENTRAL U2U BRIDGE (FTDI 230X) acts as a bridge to convert USB to UART.
