Sparkfun原廠 RS232 Shifter 轉換器 - SMD (PRT-00449)
Product Overview 產品概述
The smallest and easiest to use serial conversion circuit on the market! This board has one purpose in life - to convert RS232 to TTL and vice versa (TX and RX). This will allow a microcontroller to communicate with a computer. Shifter SMD is powered from the target application and can run at any voltage! That's right - power the board at 5V and the unit will convert RS232 to 5V TTL. Power the board at 2.8V and the Shifter board will convert RS232 to 2.8V CMOS TTL. Includes two indicator LEDs for TX and RX. Runs from 300bps up to 115200bps.
市面上最小巧、最容易使用的串列轉換電路！這款電路板的最終用途就是將 RS232 轉換為 TTL 訊號，反之亦然（TX 和 RX）。這樣一來，微控制器就能與電腦通訊了。 Shifter SMD 模組由目標應用供電，可在任意電壓下運作！沒錯，只需為電路板供電 5V，它就能將 RS232 轉換為 5V TTL 訊號。只需為電路板供電 2.8V，Shifter 模組就能將 RS232 轉換為 2.8V CMOS TTL 訊號。它包含兩個用於 TX 和 RX 的 LED 指示燈。工作速率範圍為 300bps 至 115200bps。
Unit comes fully assembled and tested as shown. You can either solder a 4-pin header or individual wires.
設備已完全組裝並測試完畢，如圖所示。您可以焊接 4 針接頭或單根電線。
Dimensions: 1.25x1.15"
