The board is based around the MCP23017 16-bit I\/O expander from Microchip Technology Inc. A MCP23017 expander is included on the board allowing you to connect up to 16 digital inputs or outputs to the Raspberry Pi.  The IO Pi Zero Expander is powered through the host Raspberry Pi using the GPIO port and extended pins on the GPIO connector allow you to stack the IO Pi Zero along with other expansion boards.\u003c\/p\u003e\n\u003cp\u003eThe I2C address bits are selectable using the on-board jumpers. The MCP23017 supports up to 8 different I2C addresses so with one MCP23017 device on each IO Pi Zero you can stack up to 8 IO Pi Zero boards on a single Raspberry Pi giving a maximum of 128 I\/O ports.\u003c\/p\u003e\n\u003cp\u003eThe IO Pi includes a 5V port that can be isolated from the Raspberry Pi via an isolation solder jumper so you can use a seperate high current power supply to power the IO Pi reducing the load on the Raspberry Pi.

This gives 8 possible I2C addresses for each chip.  The IO Pi Zero contains one MCP23017 chip so you can stack up to 8 IO Pi boards on a single Raspberry Pi.  To simplify address selection on the IO Pi we have included a set of address selection pads which can be configured by applying a small solder bridge across the required pads.

With the PUD HAT from ModMyPi, adding multiple pull-up or pull-down resistors to your Raspberry Pi project is easy! The PUD HAT is an expanded version of the smaller PUD board.\u003c\/p\u003e\n\u003cp\u003eIf you want to detect an \"output\" with your Raspberry Pi, like a button being pressed or a motion sensor detecting movement, we can configure our Raspberry Pi's GPIO pin as an \"input\". That input pin can be in three states (known as Tri-State logic); \"high\", when 3.3V is applied, \"low\", when the pin is connected to 0V, and \"floating\" when the state is undefined. Floating voltages are troublesome in electronics as the input can either read high or low depending on various fluctuations in electrical noise. Like a gate flapping open and closed in the wind, someone needs to lock the gate closed, or wedge it open. If you leave it flapping, it's likely to hit someone on their bottom on the way through!\u003c\/p\u003e\n\u003cp\u003eLike our gate, the best way to avoid a floating input is to \"tie\" your input pin either high or low to create a default state. This is usually achieved through the use of a pull-up or pull-down resistor, either connecting our input pin via a resistor to the Pi's 3.3V to achieve a 3.3V high state, or the GND line to achieve 0V low state.\u003c\/p\u003e\n\u003cp\u003eOur PUD HAT takes the messy wiring out of adding a pull-up or pull-down resistor to your circuit. Simply wire up the sensor output to the single pin on the PUD HAT and add a shunt jumper to either pull up (u) or down (d)! Therefore when you apply a signal voltage from your sensor or switch, the Pi is easily able to sense into which logic state the pin has been pulled! No more trouble from floating I\/O's, the PUD HAT adds a jumper configurable pull-up or pull-down 10k? resistor to 26 of the Pi's GPIO pins.\u003c\/p\u003e\n\u003cdiv\u003e\u003cstrong\u003eThe product comes fully assembled with our push-fit \"plug \u0026amp; play\" Single Shroud Header, Socket Header, and 14mm HAT Mounting Kit\u003cstrong\u003e,\u003c\/strong\u003e so there's no soldering required.\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003cstrong\u003eThe PUD HAT Features:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eAdd a pull-up or pull-down resistor to your GPIO with the swap of a jumper!\u003c\/li\u003e\n\u003cli\u003eCompatible with all 40-pin Raspberry Pi Models\u003c\/li\u003e\n\u003cli\u003eHAT compliant layout is easy to integrate into any Raspberry Pi Project\u003c\/li\u003e\n\u003cli\u003eUses SMT Socket Header \u0026amp; 40 Pin Extra Tall \"Single Shroud\" Header\n\u003c\/li\u003e\n\u003cli\u003eIncludes 14mm Mounting Kit\n\u003c\/li\u003e\n\u003cli\u003eFully Assembled - No Soldering Required\u003c\/li\u003e\n\u003cli\u003eIn-line 1k current limiting resistors on each GPIO\u003c\/li\u003e\n\u003cli\u003e10k pull-up or pull-down resistors on each GPIO\u003c\/li\u003e\n\u003cli\u003eAll 26 GPIO pins can be configured independently \u003c\/li\u003e\n\u003cli\u003eIncludes 26 x 2 Pin Shunt Jumpers \u0026amp; 1 x PUD HAT\u003c\/li\u003e\n\u003cli\u003eJumper configurable pull-up or pull-down resistor on pins:\n\u003cul\u003e\n\u003cli\u003e3 (BCM 02)\u003c\/li\u003e\n\u003cli\u003e5 (BCM 03)\u003c\/li\u003e\n\u003cli\u003e7 (BCM 04)\u003c\/li\u003e\n\u003cli\u003e29 (BCM 05)\u003c\/li\u003e\n\u003cli\u003e31 (BCM 06)\u003c\/li\u003e\n\u003cli\u003e26 (BCM 07)\u003c\/li\u003e\n\u003cli\u003e24 (BCM 08)\u003c\/li\u003e\n\u003cli\u003e21 (BCM 09)\u003c\/li\u003e\n\u003cli\u003e19 (BCM 10)\u003c\/li\u003e\n\u003cli\u003e23 (BCM 11)\u003c\/li\u003e\n\u003cli\u003e32 (BCM 12)\u003c\/li\u003e\n\u003cli\u003e33 (BCM 13)\u003c\/li\u003e\n\u003cli\u003e8 (BCM 14)\u003c\/li\u003e\n\u003cli\u003e10 (BCM 15)\u003c\/li\u003e\n\u003cli\u003e36 (BCM 16)\u003c\/li\u003e\n\u003cli\u003e11 (BCM 17)\u003c\/li\u003e\n\u003cli\u003e12 (BCM 18)\u003c\/li\u003e\n\u003cli\u003e35 (BCM 19)\u003c\/li\u003e\n\u003cli\u003e38 (BCM 20)\u003c\/li\u003e\n\u003cli\u003e40 (BCM 21)\u003c\/li\u003e\n\u003cli\u003e15 (BCM 22)\u003c\/li\u003e\n\u003cli\u003e16 (BCM 23)\u003c\/li\u003e\n\u003cli\u003e18 (BCM 24)\u003c\/li\u003e\n\u003cli\u003e22 (BCM 25)\u003c\/li\u003e\n\u003cli\u003e37 (BCM 26)\u003c\/li\u003e\n\u003cli\u003e13 (BCM 27)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eTo pull pin-up, connect the jumper across \"u\" and the center pin\u003c\/li\u003e\n\u003cli\u003eTo pull pin down, connect the jumper across \"d\" and the center pin\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTutorials\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHow to use the ModMyPi PUD HAT\u003c\/p\u003e","brand":"ModMyPi","offers":[{"title":"Default Title","offer_id":48401558208733,"sku":"xdv1787257936016","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/1875\/4525\/files\/pud-hat-pull-updown-resistor-hat-discontinued_1.jpg?v=1787257944"},{"product_id":"pud-board-pull-updown-resistor-board-discontinued","title":"PUD Board (Pull-Up\/Down Resistor Board) [Discontinued]","description":"\u003cp\u003eWhether you're pulling-up or pulling-down, there's no need to frown!
