The LIDAR-Lite v4 Qwiic from GARMIN is a high-performance, wireless optical distance measurement sensor that doesn't require any soldering to get started. This is the ideal solution for drone, robot, IoT, or unmanned vehicle operations when space is tight and power is limited. This sensor has up to a 10 meter range, 1cm resolution, and requires 85mA during data acquisition. The user can read and write to the LIDAR-Lite v4 using the I2C protocol; this is where the addition of the SparkFun Qwiic system really shines. The LIDAR sensor requires 5V to operate but runs on 3V3 logic. With a 5V boost circuit and an easy-to-use Qwiic connector you can power the sensor and get distance measurements over Qwiic all with a single piece of hardware. /是一款高性能無線光學距離測量感測器,無需任何焊接即可啟動。當空間緊張且電力有限時,這是無人機、機器人、物聯網或無人駕駛車輛操作的理想解決方案。此感測器的測量範圍可達 10 米,分辨率為 1 厘米,數據採集時需要 85mA 電流。使用者可以使用I 2 C協定對LIDAR-Lite v4進行讀寫;這就是 SparkFun Qwiic 系統的真正亮點。 LIDAR 感測器需要 5V 才能運行,但以 3V3 邏輯運行。借助 5V 升壓電路和易於使用的 Qwiic 連接器,您可以透過單一硬體為感測器供電並透過 Qwiic 獲得距離測量結果。
The LIDAR sensor works by sending out an infrared beam and measuring the time it takes to be reflected back. The LIDAR-Lite v4 utilizes LEDs rather than a laser for this iteration; therefore, it is inherently eye-safe under normal usage. The built-in nRF52840 microcontroller runs a pre-loaded "out of the box" stock application to calculate the distance between itself and something in front of it. The equipped nRF52840 also allows developers to create custom applications to expand on the "out of the box" functionality or connect to an external micro-controller running a custom user application./光達感測器的工作原理是發出紅外線光束並測量反射回來所需的時間。 LIDAR-Lite v4 在這次迭代中使用 LED 而不是雷射;因此,在正常使用情況下,它本質上對眼睛是安全的。內建 nRF52840 微控制器運行預先載入的「開箱即用」庫存應用程式來計算其自身與前方物體之間的距離。配備的 nRF52840 還允許開發人員創建自訂應用程式以擴展「開箱即用」功能或連接到運行自訂用戶應用程式的外部微控制器。
The SparkFun LIDAR Lite v4 Arduino library makes getting data as easy as a call to the getDistance() function. The library also supports changing the I2C address of each LIDAR and provides an easy example of how to do so. Its low power-consumption and I2C address configuration means you can daisy-chain up to 10 of these sensors on one microcontroller platform.
Note: The I2C address of the Qwiic LIDAR-Lite v4 is 0x62 and is software-configurable to any address. A multiplexer/Mux is required to communicate to multiple Qwiic LIDAR-Lite v4 sensors on a single bus. If you need to use more than one Qwiic LIDAR-Lite v4 sensor consider using the Qwiic Mux Breakout./
注意: Qwiic LIDAR-Lite v4 的I 2 C 位址為 0x62,可透過軟體設定為任何位址。需要多路復用器/Mux 才能與單一總線上的多個 Qwiic LIDAR-Lite v4 感測器進行通訊。如果您需要使用多個 Qwiic LIDAR-Lite v4 感測器,請考慮使用Qwiic Mux Breakout。
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong. / 是由 I 2 C 感測器、執行器、屏蔽層和電纜組成的生態系統,可加快原型設計速度並不易出錯。所有支援 Qwiic 的板均使用常見的 1 毫米間距、4 針 JST 連接器。這減少了所需的 PCB 空間,並且極化連接意味著您不會錯誤地連接它。
