We found the smallest PS\/2+USB keyboard available, a mere 8.75\" x 4.65\" x 0.6\" (220mm x 118mm x 16mm)! It's small but usable to make a great accompaniment to either a microcontroller project or a computer such as the Beagle Bone or Raspberry Pi. The keyboard supports either USB or PS\/2 interface and will automatically adjust to whichever its plugged into (there's an adapter included).\u003cbr\u003e\u003cbr\u003eComes with a full QWERTY keyboard, and has a num-lock number pad. Nearly all microcontrollers have existing PS\/2 keyboard examples that would work fine with this keyboard. For Ardiuno users, we tried out PJRC's PS2_Keyboard library with great success - just check the 'simple text' example for which pins you can connect to on your 'duino (on an Uno we used digital pins 2 and 3). We suggest our PS\/2 adapter cable to make the wiring easy. Start typing and you'll see the data appear in the serial terminal!\u003cbr\u003e\u003cbr\u003eTo use with a Raspberry Pi, change the keyboard to USA PC104 layout:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSwitch to root user.\u003c\/li\u003e\n\u003cli\u003eRun 'dpkg-reconfigure locales' and change from en_GB.UTF-8 to en_US.UTF-8.\u003c\/li\u003e\n\u003cli\u003eRun 'dpkg-reconfigure keyboard-configuration' and change the keyboard to USA PC104 (again, change as needed).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cul\u003e\n\u003cli\u003e78 Keys\u003c\/li\u003e\n\u003cli\u003ePlastic case dimensions: 8.75\" x 4.65\" x 0.6\" (220mm x 118mm x 16mm)\u003c\/li\u003e\n\u003cli\u003eWeight: 220 grams\u003c\/li\u003e\n\u003cli\u003eUSB or PS\/2 protocol\u003c\/li\u003e\n\u003cli\u003eCable length: 48 inches \/ 1.25m\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43493225955405,"sku":"xqq1787257505990","price":18.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/miniature-keyboard--microcontroller-friendly-ps2-and-usb_1.jpg?v=1787257510","url":"https:\/\/www.grandorchard.shop\/products\/miniature-keyboard-microcontroller-friendly-ps2-and-usb","provider":"My Store","version":"1.0","type":"link"}
