GPIO Expander - Arduino Shield
16 Channel general purpose IO expander for Arduino Uno R3 boards. Provides higher current (500mA) and voltages (50V) per pin than Arduino. Voltage via Vin from Arduino or separate DCC jack - up to 50V and 500mA per pin. This uses the i2c interface, which is shared, so does not utilize any of the dedicated I/O pins of the Arduino. Each board is addressable via jumpers for up to 8 expanders on one Arduino plus possibly additional i2C devices depending on the addresses.
BOM:
1x MCP23017 - Microchip MCP23017-E/SP - Mouser Part
2x ULN2803A - STMicroelectronics - Mouser Part
1x CUI Inc PJ-202A - Sparkfun PRT-00119 (Optional - Only needed if you plan to NOT use Vin from Arduino Uno)
Optional Shield Stacking Headers - Useful to stack shield with other shield - not that all pins are transferred up to next shield.
1x - Shield Stacking Headers Kit - Adafruit
Optional male pins for jumpers for board - since the spacing is standard .1 inch (2.54mm) there are many options.
2x 2x5 90deg Header - suggested 90 deg headers for outputs if stacking shields - Mouser Part
4x Jumpers - Mouser Part
1x 1x12 Header - Break into 4x 1x3 for A0, A1, A2, Power Selectors Mouser Part
Arduino Library
Use the Adafruit MCP23017 library for this i2c connector.

Programmable LP55231 led driver with three common-cathode Kingbright rgb leds in a standard Teensy 3.1 add-on board. Board can be mounted onto a teensy or used on a breadboard, and can be operated from the Teensy host or as a stand-alone, LiPo-battery-operated device. Vin is between 2.7 and 5.5 V. Switched red leds to D7-9 since driven directly by VIN as per data sheet.
