{"product_id":"halcyon-wireless-usb-c-dongle","title":"Halcyon Wireless USB C Dongle","description":"\u003cp\u003eA bluetooth dongle that's small, uses USB C and is compatible with \u003cstrong\u003eany\u003c\/strong\u003e ZMK keyboard: that's the Halcyon wireless USB C dongle.\u003c\/p\u003e\n\u003cp\u003eThis dongle is useful for two reasons: when your device doesn't already have bluetooth on its own, this dongle will enable you to use your ZMK keyboard wirelessly. And two, the main reason most will want this: using a dongle \u003cstrong\u003edrastically reduces the power draw \u003c\/strong\u003eof the main half of your wireless keyboard.\u003c\/p\u003e\n\u003cp\u003eWithout a dongle, the main half will keep two connections open. One to the peripheral half, and another to the host device. This means that the main half will be able to be asleep considerably less than the peripheral half, which reflects on the battery life. Using a dongle, both halves connect directly to the dongle and will not need a connection between the two halves. Removing this second connection can save up to as much as 95% of battery consumption on the main half, so your battery can last up to twenty times longer!\u003c\/p\u003e\n\u003cp\u003eWe highly recommend using a dongle when powering your keyboard with the Coin Cell power board, as the coin cells are non-rechargeable. We estimate your coin cell will last between 6 to 9 months of use with the dongle, while the main half would last roughly two weeks without a dongle.\u003c\/p\u003e\n\u003cp\u003eWhen using a LiPo power board, using a dongle can still be useful as you'll have to charge your keyboard far less frequently. Charging your LiPo is easy to do though, so the dongle will be more of a luxury there.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUses a \u003cspan\u003e\u003cstrong\u003enRF52840\u003c\/strong\u003e module for its wireless connection, featuring an ARM Cortex-M4 processor, 1MB of embedded flash memory and 256 kB of RAM.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003ePowered by \u003cstrong\u003eZMK Firmware\u003c\/strong\u003e.\u003c\/span\u003e\n\u003cul\u003e\n\u003cli\u003eHalcyon keyboards are compatible: either through \u003ca href=\"https:\/\/canary.composer.splitkb.com\/#\/firmware\"\u003edownloadable firmware files\u003c\/a\u003e which you can customise with ZMK Studio, or by \u003ca href=\"https:\/\/docs.splitkb.com\/product-guides\/halcyon-series\/resources\/compiling-firmware-zmk\"\u003ecompiling it yourself\u003c\/a\u003e through a provided sample repository.\u003c\/li\u003e\n\u003cli\u003eOther ZMK-powered keyboards are compatible too, by \u003ca href=\"https:\/\/docs.splitkb.com\/product-guides\/halcyon-dongle\/firmware\"\u003efollowing our comprehensive setup guide\u003c\/a\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasily flashable\u003c\/strong\u003e: double-tap the button and the dongle will present itself as an attached drive.
