Overview
ROCK 4 SE is a class-leading single-board computer developed by OKdo in collaboration with Radxa. It’s a reliable, robust, low-power and high-performing SBC based on the powerful Rockchip RK3399-T processor, big. LITTLE™ Arm® Dual Cortex-A72® CPU, Arm Mali™ - T860MP4 GPU and 4GB dual channel LPDDR4 RAM. The board benefits from an extensive list of high-quality features, such as an on-board antenna, RTC, Wi-Fi 802.11 b/g/n/ac, Bluetooth 5 and BLE modules, an audio jack with microphone in, a 4K HDMI port 60fps, user configurable USB HOST/OTG mode, M.2 memory expansion, eMMC robust memory slot and much more.

trying to understand how to convert serial data to digital data onb arduino micro
Whether granting access to public transit or restricting unauthorized personnel in buildings, NFC card readers can be extremely useful. Although most might not consider how they work – and simply happy getting through a turnstile – there’s a lot going on behind the scenes. In his video, Daniel Raines shows off a pair of prototype access control units (ACUs) that he’s constructed. The two networked devices are each based on a Raspberry Pi Compute Module 4 along with an Arduino Micro that controls six relays to allow or deny entry, provide feedback, fire, and lock up. More details on the project can be found in Raines' clip below.
