While standard chips like the CP2102 or CH340 provide a single serial connection, this powerful Silicon Labs IC gives you \u003cb\u003etwo independent UART channels\u003c\/b\u003e (one Standard, one Enhanced) from a single USB port. This is an absolute game-changer for drone diagnostics, robotics, and custom development boards where you need to communicate with a Flight Controller on one port and configure a GPS, VTX, or Telemetry module on the other simultaneously.\u003c\/p\u003e\n\u003cp\u003eThe CP2105 is highly integrated, featuring a built-in USB 2.0 full-speed transceiver, integrated clock oscillator (no external crystal required), and an internal voltage regulator. This minimalist external component requirement, combined with its ultra-compact 4x4 mm QFN-24 package, makes it the ultimate choice for space-constrained diagnostic dongles and professional DIY electronics. Additionally, it features programmable GPIO pins that can be used for controlling LEDs or resetting microcontrollers (like ESP32\/ESP8266) into bootloader mode.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eTwo-for-One Efficiency:\u003c\/b\u003e Enumerates as two separate COM ports on your PC from a single USB connection, allowing simultaneous dual-device communication.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHigh Integration:\u003c\/b\u003e Requires no external crystal oscillator or EEPROM, vastly simplifying circuit design and saving precious PCB space.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHigh-Speed Data:\u003c\/b\u003e The Enhanced channel supports baud rates up to 2 Mbps, perfect for high-frequency Blackbox data dumping or flashing firmwares quickly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBuilt-in GPIO:\u003c\/b\u003e Features accessible GPIO pins that are commonly used to trigger the BOOT\/EN pins on ESP-based microcontrollers for auto-programming.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePart Number:\u003c\/b\u003e CP2105-F01-GMR\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eIC Type:\u003c\/b\u003e Single-Chip USB to Dual UART Bridge\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eInterfaces:\u003c\/b\u003e 1x Enhanced UART (up to 2 Mbps), 1x Standard UART (up to 921 kbps)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eUSB Standard:\u003c\/b\u003e USB 2.0 Full-Speed\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eOperating Voltage:\u003c\/b\u003e 3.0V – 3.6V (with 5V-tolerant inputs)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePackage Type:\u003c\/b\u003e QFN-24 (4x4 mm, SMD\/SMT)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RC-LIFE","offers":[{"title":"Default Title","offer_id":54285775995218,"sku":null,"price":23.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1065\/8067\/2850\/files\/2105.jpg?v=1786961245","url":"https:\/\/rc-life.com\/pl\/products\/cp2105-f01-gmr-dual-uart-to-usb-bridge-controller-qfn-24","provider":"rc-life","version":"1.0","type":"link"}
