SparkFun 16 Output I/O Expander Breakout
SX1509
Are you low on I/O? No problem! 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 you can dim LEDs. It can be set to blink or even breathe pins at varying rates. This breakout is similar to a multiplexer or "mux," in that it allows you to get more IO from less pins. And, with a built-in keypad engine, it can interface with up to 64 buttons set up in an 8x8 matrix.

Dual Wide Range Power Monitor
LTC2992
The LTC®2992 is a rail-to-rail system monitor that measures current, voltage, and power of two supplies. It features an operating range of 2.7V to 100V and includes a shunt regulator for supplies above 100V. The voltage measurement range of 0V to 100V is independent of the input supply. Two ADCs simultaneously measure each supply’s current. A third ADC monitors the input voltages and four auxiliary external voltages. Each supply’s current and power is added for total system consumption. Minimum and maximum values are stored and an overrange alert with programmable thresholds minimizes the need for software polling. Data is reported via a standard I2C interface. Shutdown mode reduces current consumption to 25μA typically.
