General

This is a full 8-pin breakout for the SIM socket allowing direct access to SIM communication.

The TLC5940 is a 16 channel PWM unit with 12 bit duty cycle control (0-4095), 6 bit current limit control (0-63), and a daisy chainable serial interface.

This is a breakout board for the Texas Instruments TXB0104 module. The TXB0104 is a 4-bit bidirectional voltage-level translator with automatic direction sensing. 

This simple breakout board makes it easy to use our LED tactile switches in a breadboard, or your next project.

This is a clever little breakout board for both the RGB and R/G illuminated rotary encoders.

MOSFETs are awesome. They're like a switch that you flip electronically! This MOSFET Power Controller makes it easy to switch a battery supply on and off using your favorite microcontroller. The board also has sewable pads so you can use it in e-textile projects that need more juice.
