{"title":"I2C to 8-Channel Solenoid Driver","handle":"adafruit-i2c-to-8-channel-solenoid-driver","url":"/products/adafruit-i2c-to-8-channel-solenoid-driver","description":"This driver board makes it much easier to control multiple solenoids from a microcontroller over I2C. It uses an MCP23017 GPIO expander so you do not need to dedicate lots of pins just to switch a bank of clicky, inductive loads.Solenoid power connects through the centre terminal blocks, with each solenoid wired to the remaining terminal blocks. Each channel has its own AO3406 N-Channel MOSFET, flyback diode for inductive kick-back protection, and a red indicator LED that lights when the transistor is on.The MCP23017 also has its B port broken out for general-purpose I/O such as LED driving or button inputs. Three address pins can be jumpered so up to 8 boards can share the same I2C bus for larger builds.It works with 3V or 5V power and logic, making it suitable for boards ranging from Arduino-compatible Metro 328 projects to Raspberry Pi setups. STEMMA QT / Qwiic compatible JST SH connectors make I2C wiring simple and help share the bus with other STEMMA QT, Qwiic, Grove or compatible devices. A QT cable is not included.Specifications:GPIO expander: MCP23017Solenoid channels: 8Solenoid power supply: 3V to 24V DC maximumChannel MOSFET: AO3406 N-Channel MOSFETMOSFET Vds rating: 30VdsMOSFET peak current: 3.6A peakMOSFET RdsOn: 70mΩ RdsOnMCP23017 total IO pins: 16 total IO pinsAddress pins: three address pinsDaisy-chain capacity: up to 8 boardsTotal solenoids when daisy-chained: 64 solenoidsPower and logic: 3V or 5V power and logicProduct Dimensions: 51.0mm x 28.0mm x 10.2mm / 2.0\" x 1.1\" x 0.4\"Product Weight: 10.7g / 0.4oz","vendor":"Adafruit","product_type":"Solenoid Driver","in_stock":true,"options":[],"variants":[{"id":15763,"title":"Default Title","sku":"AF-6318","mpn":"ADA6318","price":36.75,"on_sale":false,"in_stock":true,"available_quantity":100}]}
