Don’t mind the picture… there’s a reason 😅 ## Features - I2C controlled, expands 2 signal pins as 16 I/O pins - I2C address configurable by shorting the A0/A1/A2 jumpers - Provides two connector options: PH2.0 terminal and/or solder pads, allows multi I2C modules to be stacked - Onboard voltage translator, compatible with 3.3V/5V level ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07P2H1NZG | | Best Sellers Rank | #79 in Computer Motherboards #263 in Single Board Computers (Computers & Accessories) | | Brand | waveshare | | Customer Reviews | 4.3 4.3 out of 5 stars (92) | | Date First Available | October 15, 2018 | | Item Weight | 0.352 ounces | | Item model number | MCP23017 IO Expansion Board | | Manufacturer | Waveshare | | Operating System | Linux | | Package Dimensions | 9.09 x 7.01 x 0.43 inches | | Power Source | DC | | Processor Brand | Waveshare | | RAM | DDR3 | | Series | MCP23017-E/SP MCP23017 16-Bit I/O Expander with Serial Interface | | Wireless Type | Infrared | ## Product Details - **Brand:** waveshare - **Connectivity Technology:** I2C, Infrared - **Included Components:** MCP23017 IO Expansion Board, PH2.0 20cm 6Pin cable - **Model Name:** MCP23017-E/SP MCP23017 16-Bit I/O Expander with Serial Interface - **Operating System:** Linux ## Images ![Waveshare MCP23017 IO Expansion Board I2C Interface Expands 16 I/O Pins Compatible with Both 3.3V and 5V Levels - Image 1](https://m.media-amazon.com/images/I/61aNbX11TbL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by E***B on July 7, 2026* Works well with inputs and outputs between ESP32, LEDs, switches and LCD. No issues setting up or connecting. ### ⭐⭐⭐⭐⭐ The perfect expander! The MCP23017 is a must! *by J***N on July 23, 2025* What a great little board! I needed these to expand on my raspberry Pi and ended up buying 4 of these and run them all on the i2c bus! They work flawlessly! They are easy to use and tons of libraries out there to work with! Don’t mind the picture… there’s a reason 😅 ### ⭐⭐⭐⭐⭐ Worked perfect for large IO expansion *by P***A on October 25, 2020* I needed a whole lot of IO ports for my Raspberry. I bought a total of seven of these. This board was super easy to use both for configuring input/output ports. Interrupts are a nice feature, as well as the ability to programmatically pull input port high. Accessible on port x20 - x27 (default), so you can run 8 of these for a total of 64 IO ports. I was able to convert the C examples to Ruby without any fuss. Pro: * Easy to use for IO expansion. * Nice features (IO configuration, pull ups, interrupts) * Great example code (C and Python). Cons: * Hard to mount as there is only a single set of holes in the board (ideally there would have been a hole on each corner). * Soldering the address jumpers (A0/1/2) too a little work ## Frequently Bought Together - Waveshare MCP23017 IO Expansion Board I2C Interface Expands 16 I/O Pins Compatible with Both 3.3V and 5V Levels - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - ANMBEST 2PCS 4 Channel 5V Relay Module with Optocoupler High or Low Level Trigger Expansion Board for Raspberry Pi Arduino --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/119531793-waveshare-mcp23017-io-expansion-board-i2c-interface-expands-16-i](https://www.desertcart.in/products/119531793-waveshare-mcp23017-io-expansion-board-i2c-interface-expands-16-i) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-09-12*
