The Beitong K1 is said to be the only mechanical keyboard that supports Bluetooth 5. The keyboard is wirelessly connected to iOS and Android Bluetooth 4.0 (and higher) smartphones and tablets via Nordic SoC devices. nRF52832 SoC provides Bluetooth 5 support, including 2x Wireless raw data bandwidth (2Mbps), allowing faster data transfer between the keyboard and user equipment for faster response times.
Developed for smartphone and tablet games, the keyboard is compatible with most leading mobile games. Its key count is reduced to 61 keys, which reduces the form factor to 291×101×39mm for easy portability. The punch function increases the speed and accuracy of the buttons, as each button is completely scanned independently by the keyboard hardware, so the system can correctly detect each button no matter how many keys are pressed or held simultaneously.
The keyboard is powered by a 1000mAh rechargeable battery and provides approximately 30 hours of continuous operation with the backlight turned off. One of the reasons for its low power consumption is the low power consumption of the nRF52832 SoC. The SoC device has been carefully designed to have a peak RX / TX With a 2.4 mA 2.4 GHz RF component, the fully automated power management system reduces power consumption by up to 80% compared to the Nordic nRF51 Series SoC for a low-power Bluetooth solution with 58 CoreMark / mA performance. Twice the same kind of competitive equipment.
Nordic's nRF52832 is a powerful multi-protocol SoC device ideal for low-power Bluetooth and 2.4GHz ultra-low-power wireless applications. The nRF52832 integrates a 64MHz, 32-bit Arm® CortexTM M4F processor with 2.4GHz multi-protocol RF components. (Supports Bluetooth 5, ANTTM and proprietary 2.4GHz RF software) with -96dB receiver sensitivity, 512kB Flash memory and 64kB RAM.
The SoC device is equipped with Nordic's S132 protocol stack and Bluetooth 5 certified RF software protocol stack for building advanced low-power Bluetooth applications. The S132 protocol stack supports central, peripheral, broadcaster, and observer low-power Bluetooth-enabled character for up to 20 simultaneous connection and parallel role operations.
