The 金沙线上娱乐场SparkFun RFID Qwiic Kit is a simple,yet all-in-one I2C based RFID starting point for the ID-3LA,ID-12LAand ID-20LA readers.Simply plug a reader into the headers and use a Qwiic cable to connect to any Qwiic enabled development board,then scan your 125kHz ID tag and the unique 32-bit ID will be shown on the screen.This kit comes with everything you need to get started.Spar金沙线上娱乐场kfun RFID QWIIC阅读器，一个ID-12LA读卡器，a couple of RFID cards,and a cable to get you hooked up.Just plug this into any Qwiic enabled development board and you are good to go.
Utilizing the onboard ATtiny84A,the Qwiic RFID takes the six byte ID tag of your 125kHz RFID card,attaches a time stamp to it,and puts it onto a stack that holds up to 20 unique RFID scans at a time.这个信息很容易理解2C commands.The unit comes with a read LED and buzzer,but don't worry,有一个跳线，你可以切断，以禁用蜂鸣器，如果你想。
Spar金沙线上娱乐场kfun Qwiic Connect系统是我的生态系统2C sensors,执行器，屏蔽和电缆，使原型更快，更不容易出错。All Qwiic-enabled boards use a common 1mm pitch,4-pin JST connector.This reduces the amount of required PCB space,极化连接意味着你不能把它连接错。
If a board needs code or communicates somehow,you're going to need to know how to program or interface with it.编程技巧都是关于通信和代码的。
Skill Level: Rookie-您需要更好地了解什么是代码，以及它的工作原理。You will be using beginner-level software and development tools like Arduino.你会直接处理代码,but numerous examples and libraries are available.Sensors or shields will communicate with serial or TTL.
If it requires power,you need to know how much,所有的针都做什么，and how to hook it up.You may need to reference datasheets,schematics,and know the ins and outs of electronics.
Skill Level: Rookie- You may be required to know a bit more about the component,such as orientation,or how to hook it up,in addition to power requirements.You will need to understand polarized components.
