Product details

Slice of Pi/O PCB Kit For Raspberry Pi

• An add-on board for the raspberry Pi featuring the Microchip MCP23017 I/O controller
• Easy to assemble kit offers similar features found on the Gert board
• 16 input/output lines driven off the external chip
• This device offers protection to the Pi and can drive more power per pin
• Same size as the Slice of Pi board
• Boards can be daisy chained to give up to 128 ports

The device supports 4 wire daisy chain connector (PWR/GND/SCL/SDA), breakout for Interrupt A & B, daisy chain up to 8 for 128 I/O pins
Supplied with 2 x 8 way 0.1" pitch layout for of all 16 I/O's and 2 x 8 way 0.1" pitch common ground for ease of use, 0.1uf decoupling capacitor, IC and IC holder
Rated 4 out of 5 by from Nice little board Provides both the buffered pins (through the chip) and also thru pins for the original (unbuffered) GPIO pins. It sits on top of the PI, directly plugging into the GPIO. The MCP23017 chip uses different addressing than the logical sequence of the PI's GPIO set. See: http://www.averagemanvsraspberrypi.com/2013/08/controlling-leds-with-ciseco-slice-of_22.html I followed this and used a 100 ohm resistor and a 1.7v 10ma Red LED to light up on PIN 1. That took me a few software errors in Python - having to load the SMBUS library and remember my board was a revision 2, so had to use SMBUS(1). Ensure you check the connections with a continuity meter, I found at least 1 pin where my soldering was off. In hindsight, I'd probably be lazy next time and buy a pre-built one or even better one where a buffered breakout is at the end of a ribbon cable through the PI's case :-)

Are these I/Os analouge or digital?

Asked by: Mike
These are analogue.
