Simple but effective - this breakout board has a CR1220 coin cell battery holder soldered on, an on/off switch and 0.1" pitch breakout pins for easy connecting. Great for powering very low-current...

These are very interesting 5mm diffused RGB LEDs - instead of having 4 pins to control 3 LEDs, they have only two leads - power and ground. When powered, the LEDs perform a slow fade through the...

Spin two DC motors, step one bi-polar or uni-polar stepper, or fire off two solenoids with 1.2A per channel (3A peak) using the TB6612. These are perhaps better known as "the drivers in our assembled...

A Feather board without ambition is a Feather board without FeatherWings! This is the Non-Latching Mini Relay FeatherWing. It gives you power to control, and control over power. Put simply,...

LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays. This is a very standard, yellow LED. The lens is 3mm in diameter and it is...

Need some indicators? We are big fans of these diffused green LEDs, as featured in the LoL shield. They are fairly bright so they can be seen in daytime, and from any angle. They go easily into a...
