The extra 8 MB of SPI Flash is great for sound effects projects where you want to play up to 3 minutes of WAV files.\u003c\/p\u003e\n\u003cp\u003eOn each side of the Hallowing are JST-PH plugs for connecting external devices. The 3-pin JSTs connect to analog pins on the SAMD21, so you can use them for analog inputs. Adafruit label one for Neopixel and one for Sensors since they think most people will have one of each. The 4-pin JST connector connects to the I2C port and you can fit Grove connectors in it for additional hardware support.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes not come with a Lipoly battery!\u003c\/strong\u003e \u003ca href=\"\/en-eu\/products\/lipo-battery-pack\" target=\"_blank\"\u003eA\u003c\/a\u003e\u003ca href=\"\/en-eu\/products\/lipo-battery-pack\" target=\"_blank\"\u003eny 3.7\/4.2V Adafruit Lipoly will do the trick.\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eComes fully assembled and ready to be your spooky friend. Adafruit install the UF2 bootloader on it so updating code and converting it to CircuitPython is easy. \u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-hallowing\" target=\"_blank\"\u003eCheck out the Adafruit Learn guide for software, libraries, example code, schematics, datasheets and more!\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-hallowing\" target=\"_blank\"\u003eCheck out the Adafruit Learn guide for software, libraries, example code, schematics, datasheets and more!\u003c\/a\u003e\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eProduct Dimensions: 60.0mm x 51.0mm x 11.0mm \/ 2.4\" x 2.0\" x 0.4\"\u003c\/li\u003e\n\u003cli\u003eProduct Weight: 17.5g \/ 0.6oz\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":12954970587219,"sku":"ADA3900","price":34.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/3900-08.jpg?v=1653318644","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-hallowing-m0-express","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
