The Texas Instruments TPS2113A autoswitching power multiplexer allows you to switch seamlessly between two power sources of 2.8 V to 5.5 V while blocking reverse current into either source. The power multiplexer (or mux) has an adjustable current limit that can be set as high as 2 A and an adjustabl..
The SX1509 Breakout is a 16-channel GPIO expander with an I2C interface – that means with just two wires, your microcontroller can interface with 16 fully configurable digital input/output pins. But the SX1509 can do so much more than just simple digital pin control. It can produce PWM signals, so y..
The SparkFun FTDI SmartBasic is a variation on our classic FTDI Basic board which allows you to connect a second device to the hardware serial port on an Arduino Pro, Pro Mini, or other USB-less board without compromising the ability to bootload code from the Arduino IDE. The FTDI SmartBasic hardwar..
