It offers configurable input/output pins with interrupt support, strong 25mA drive current per IO, and supports high-speed I2C communication up to 1.7MHz. With 3 address pins enabling up to 8 modules on a bus, it scales to 128 IO ports, ideal for complex SBC or microcontroller projects requiring extensive IO expansion. ## Description Parameters: Operating voltage：3.0V-5.5V Drive chip：MCP23017 Number of IO: 16 (input, output, interruption) Drive power supply: 25mA1 12C frequency: 100KHz, 400KHz, 1..7MHz Working temperature: -40 Celsius -125 Celsius Chip level: Industrial grade Parallel multiple: Up to 8 Driver: 51 and Arduino Module size: 65mm*19mm Pin description VCC: Power source input (3.0V-5.5V) GND: Power negative electrode (0V) SCL: 12C clock line (SCL connecting single chip IO pin or MCU 12C interface) SDA: 12C data line (SDA connecting single chip IO pin or MCU 12C interface) RST: Chip reduction (Low level effective, connecting MCU IO pin or unconnected) ITA: GPIOA port interrupt output (Connect MCU IO pin, without connection when interruption) ITB: GPIOB port interrupt output (Connect MCU IO pin, without connection when interruption) Package Included: 1pcs NOYITO MCP23017-E/SS I2C Interface 16-Channel IO Expansion Module Review: Works quite well for the Odroid H2 - This is an i2c to GPIO extender board that is very fast and easy to run on the Odroid H2 on Ubuntu. I'm using dotnet core for the application, directly calling the Ubuntu libi2c library. The best part is it will run at the highest i2c clock speed available on the H2, 1mhz clock speed. The specs here are not accurate. I can add 8 total for 128 GPIO per bus and 256 total GPIO ports if I use both i2c ports on the H2. I'll never need that many but it's nice to know it extends out that far. This could easily work on any SOC / computer with I2C ports, including windows using the FT232H usb to I2c board. If you need python examples, just google "MCP23017 python". Review: Can Be Made 'Breadboard Friensly' - If you install the 16 I/O pin header facing down (on non-component side) it will readily plug into a solderless breadboard. Install the power and data pin header up (on component side) for easy access. ## Features - This module is the 16 channel IO extension module of the 12C interface, and built in the MCP23017 chip of MicroChip. - Each IO can be arbitrarily configured as input or output, and a pull up resistor can be set, and the interrupt function can be enabled for the IO configured as input. The IO interface has a strong driving capacity, and the current and current can reach 25mA. - MCP23017 is a high-speed IIC interface. It supports the IIC frequency of 100KHz, 400KHz and 1.7MHz. - The chip has 3 address pins, which can be set up for 8 different addresses. So 8 modules can be connected through two IIC buses to achieve up to 128 IO extensions. - NOYITO MCP23017-E SS I2C Interface 16-Channel IO Expansion Module Schematic Document ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07K5MTRLS | | Best Sellers Rank | #3,843 in Single Board Computers (Computers & Accessories) | | Brand | NOYITO | | Built-In Media | 1pcs NOYITO MCP23017-E/SS I2C Interface 16-Channel IO Expansion Module | | CPU Model | Core i7-10700 | | Compatible Devices | Any SBCs or microcontrollers with I2C support | | Connectivity Technology | I2C | | Customer Reviews | 4.4 out of 5 stars 13 Reviews | | Included Components | 1pcs NOYITO MCP23017-E/SS I2C Interface 16-Channel IO Expansion Module | | Manufacturer | NOYITO | | Mfr Part Number | 8541673234 | | Model Name | MCP23017-E SS I2C Interface 16-Channel IO Expansion Module | | Model Number | 8541673234 | | Operating System | Linux | | Processor Brand | ARM | | RAM Memory Technology | LPDDR | | UPC | 680613661616 | | Unit Count | 1 Count | | Wireless Compability | 802.11b | ## Product Details - **Brand:** NOYITO - **Model Name:** MCP23017-E SS I2C Interface 16-Channel IO Expansion Module - **CPU Model:** Core i7-10700 - **Connectivity Technology:** I2C - **Operating System:** Linux ## Images ![MCP23017-E SS I2C Interface 16-Channel IO Expansion Module Compatible IIC Input and Output Expansion Board - Image 1](https://m.media-amazon.com/images/I/71sr8ECIMQL.jpg) ![MCP23017-E SS I2C Interface 16-Channel IO Expansion Module Compatible IIC Input and Output Expansion Board - Image 2](https://m.media-amazon.com/images/I/81TZEFF-HHL.jpg) ![MCP23017-E SS I2C Interface 16-Channel IO Expansion Module Compatible IIC Input and Output Expansion Board - Image 3](https://m.media-amazon.com/images/I/71EGCiQm+gL.jpg) ![MCP23017-E SS I2C Interface 16-Channel IO Expansion Module Compatible IIC Input and Output Expansion Board - Image 4](https://m.media-amazon.com/images/I/71K7ekdfqPL.jpg) ![MCP23017-E SS I2C Interface 16-Channel IO Expansion Module Compatible IIC Input and Output Expansion Board - Image 5](https://m.media-amazon.com/images/I/81CDZVlpXNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works quite well for the Odroid H2 *by A***R on August 24, 2019* This is an i2c to GPIO extender board that is very fast and easy to run on the Odroid H2 on Ubuntu.
