Sparkfun原廠 LIDAR-Lite v3HP Arduino 雷射測距模組 ( SEN-14599)

影片:https://youtu.be/rPPDmfRknvE

DESCRIPTION

    LIDAR has never looked so good! This is the LIDAR-Lite v3HP, a compact, high-performance optical distance measurement sensor from Garmin™. The LIDAR-Lite v3HP is the ideal optical ranging solution for drone, robot, or unmanned vehicle applications. Each sensor is housed in a durable, IPX7-rated housing and includes all the core features and user configurability of the popular LIDAR-Lite v3.

    The v3HP is very similar in function to that of the v3 but it can now sample faster at rates greater than 1kHz (where as the v3 is only capable of up to 500Hz). Another improvement is that this v3HP model is more power efficient with current consumption rates 40mA less than the v3 (that’s 65mA as opposed to 105mA while idle, and 85mA instead of 130mA while acquiring).

    Each LIDAR-Lite v3HP has a range of 5cm to 40m and features an edge-emitting, 905nm (1.3 watts), single-stripe laser transmitter, 8m Radian beam divergence, and an optical aperture of 12.5mm. This version of the LIDAR-Lite still operates at 5VDC (6V max) with a peak power of 1.3W and still possesses an accuracy of +/- 2.5cm at >2m. On top of everything else, the LIDAR-Lite is user-configurable, allowing adjustment between accuracy, operating range and measurement time and can be interfaced via I2C or PWM with the attached 200mm cable.

    Note: CLASS 1 LASER PRODUCT CLASSIFIED EN/IEC 60825-1 2014. This product is in conformity with performance standards for laser products under 21 CFR 1040, except with respect to those characteristics authorized by Variance Number FDA-2016-V-2943 effective September 27, 2016.

   Important: The LIDAR-Lite v3HP is NOT a drop in replacement for the LIDAR-Lite v3. The sample code specific to LIDAR-Lite v3 does not work properly with the LIDAR-Lite v3HP. Updated sample code will be showing up shortly in the Garmin Github. Until then, we recommend checking out the User Manual in the Documents tab for updated command and control registers.

Hardware Overview

Differences Between v3 and v3HP

Functionally, the LIDAR-Lite v3 and LIDAR-Lite v3HP are quite similar. The primary differences are listed here:

    案件

    LIDAR-Lite在前面有兩個管子,包含一個發射器(激光器)和接收器。你會想要面對你的目標。

    Front of LIDAR-Lite v3

    此步驟僅適用於LIDAR-Lite v3:

    在側面,您會發現連接到隨附的6線電纜的電氣端口。將線束插入端口以分離引腳。

     

    在背面,您會發現4個安裝孔,用於安裝#6或M3.5螺釘或螺栓。

    LIDAR-Lite v3的背面

    電線:LIDAR-Lite有6根導線可用於與傳感器進行通信。

    注意: 這是看單位的背面

    顏色 描述
    5V 電源(5V)
    橙子 PWR EN 電源啟用(內部上拉)
    黃色 模式 模式控制(用於PWM模式)
    綠色 SCL 2 C時鐘
    藍色 SDA I 2 C數據
    黑色 GND 地面

    功率:LIDAR-Lite v3以及LIDAR-Lite v3HP設備都需要4.5V至5.5V的直流電源(標稱值為5V)。LIDAR-LITE v3在連續工作時可以吸收135 mA的電流(怠速時為105 mA)。相反,v3HP單元在連續工作期間(怠速時為65 mA)吸收高達85 mA的電流。為了保持電平電壓,Garmin建議在電源(5V)和地(GND)之間放置一個680μF電容,盡可能靠近LIDAR單元。

    ⚡ 請注意電流消耗的差異!請注意,雖然LIDAR-Lite v3和v3HP的輸入電壓相同,但電流消耗不同

    硬件組裝

      按照下圖將LIDAR單元連接到RedBoard或其他Arduino兼容板。LIDAR-Lite可以通過I 2 C 進行通信,也可以使用脈寬調製(PWM)信號來表示測量距離。在本指南中,我們將展示如何使用I 2 C與LIDAR單元進行通信。

    LIDAR-Lite v3轉換為Arduino連接

    注意: Garmin建議使用680μF,但接近該值的任何東西都可以使用。在這個例子中,我使用了一個1000μF的電容。確保將電解電容正確添加到電路中,因為它具有極性。
