The SparkFun AS7262 Visible Spectral Sensor Breakout brings spectroscopy to the palm of your hand, making it easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS7262 Breakout is unique in its ability to communicate by both an I2C interface and serial interface using AT commands. Hookup is easy, thanks to the Qwiic connectors attached to the board — simply plug one end of the Qwiic cable into the breakout and the other into one of the Qwiic Shields, then stack the board on a development board. You’ll be ready to upload a sketch to start taking spectroscopy measurements in no time.
The AS7262 spectrometer detects wavelengths in the visible range at 450, 500, 550, 570, 600 and 650nm of light each with 40nm of full-width half-max detection. The board also has multiple ways for you to illuminate objects that you will try to measure for a more accurate spectroscopy reading. There is an onboard LED that has been picked out specifically for this task, as well as two pins to solder your own LED into.
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.

SparkFun AS7262可見光譜傳感器突破將光譜儀帶入手掌，使測量和表徵不同材料吸收和反射不同波長的光線變得更加容易。 AS7262突圍是通過I 2 C接口和使用AT命令的串行接口進行通信的獨特之處。連接器很容易，由於連接在板上的Qwiic連接器 - 只需將Qwicic電纜的一端插入插座，將另一端插入Qwiic Shields之一，然後將板堆疊在開發板上。您可以隨時上傳草圖，開始進行光譜測量。
AS7262光譜儀檢測在450,500,500,550,570,600和650nm可見光範圍內的波長，每個波長具有40nm的全寬半最大檢測。該板還有多種方式可以照亮您將嘗試測量的物體以獲得更準確的光譜讀數。有一個專門為此任務挑選的車載LED，以及兩個引腳來焊接您自己的LED。
SparkFun Qwiic Connect系統是I 2 C傳感器，執行器，屏蔽和電纜的生態系統，使原型設計更快，更不容易出錯。所有啟用Qwiic的電路板都使用通用的1mm間距，4針JST連接器。這減少了所需的PCB空間的數量，極化連接意味著您無法將其插入錯誤。
