描述
WR703N 擴展器是一款緊湊型 PCB,提供 4 端口 USB 集線器和雙 FTDI 串行端口以及額外的 GPIO。它非常適合與基於小型 TP-Link WR703N Linux 的無線路由器配合使用,或與幾乎任何帶有 USB 的計算機(例如 PC,Raspberry Pi,BBB 等)配合使用。 USB 集線器可輕鬆添加 USB 閃存驅動器來擴展路由器內部閃存,並提供其他 USB 設備(網絡攝像頭,鍵盤,聲音,協處理器等)的連接,而串行端口和 GPIO 允許多功能連接到其他設備。
它由Kean ElectronicsRobots&Dinosaurs一起設計,用於控制和自動化項目,並已用於各種設計,例如機器人技術,智能 LED 照明控制和四軸飛行器攝像頭的無線共享。
特徵
  • 體積小巧 - 設計用於在 WR703N 路由器電路板上方捎帶
  • 上行鏈路 USB 端口可以通過 mini-B 或 4 針頭連接到 WR703N
  • 3 個可用 USB 端口,備用連接選項(4 針插頭或 USB A 插座)
  • 2 個 FTDI 虛擬 COM(串行)端口 - 使用普通 6 引腳 FTDI 引腳排列(帶 RTS / CTS)
  • 端口 A 和端口 B 可選擇 3.3V 或 5V I / O 電壓
  • 8 個 GPIO(端口 A 的一部分) - 請參閱下面的 GPIO 引腳
  • 用於FTDI FT_PROG 配置實用程序的 EEPROM
  • 集成了 FTDI MPSSE 功能 - 允許 SPI / I2C / JTAG 仿真(例如,參見FTDI 應用筆記 AP_135
  • 可以使用 WR703N 供電,或者為 WR703N 供電(路由器上的短路 R113)
  • 適用於大多數操作系統(需要 FTDI 驅動程序)
  • 開源硬件設計
  • 有關 OpenWRT 和 WR703N 的信息, 參閱http://wiki.openwrt.org/toh/tp-link/tl-wr703nhttp://www.madox.net/blog/projects/tp-link-tl-wr703n/

Description
The WR703N Expander is a compact PCB providing a 4 port USB hub and dual FTDI serial ports, with additional GPIO.  It is perfect for use with the small TP-Link WR703N Linux based wireless router, or with almost any computer with USB (e.g. PC, Raspberry Pi, BBB, etc).  The USB hub makes it easy to add a USB flash drive to expand the routers internal flash storage, and provide connection of additional USB devices (webcam, keyboard, sound, co-processor, etc), while the serial ports and GPIO allow versatile connectivity to other devices.
 
It was designed by Kean Electronics in conjunction with Robots & Dinosaurs for control and automation projects, and has been used in various designs such as robotics, smart LED lighting control, and wireless sharing of quadcopter webcams.
 
 
Features
  • Compact size - designed to piggy back above WR703N router PCB
  • Uplink USB port can be via mini-B, or 4 pin header to connect to WR703N
  • 3 available USB ports with alternate connection options (4 pin header or USB A female)
  • 2 FTDI virtual COM (serial) ports – using common 6 pin FTDI pinout (with RTS/CTS)
  • Selectable 3.3V or 5V I/O voltages for Port A and Port B
  • 8 GPIO (part of Port A) – see GPIO pinout below
  • EEPROM for use with FTDI FT_PROG configuration utility
  • Incorporates FTDI MPSSE functions – allows SPI/I2C/JTAG emulation (e.g. see FTDI App Note AP_135)
  • Can be powered from WR703N, or supply power to WR703N (short R113 on router)
  • Works with most operating systems (FTDI driver required)
  • Open source hardware design
  • Info on OpenWRT and the WR703N available at http://wiki.openwrt.org/toh/tp-link/tl-wr703nandhttp://www.madox.net/blog/projects/tp-link-tl-wr703n/
 
Important
Note this unit does not include the TP-Link WR703N router
 
Specification
  • Uses Genesys Logic GL850G USB hub IC, and FT2232L dual serial IC
  • Connectors for USB and I/O come separately to allow end user customisation
  • Weight: approx 7g-20g (depending on connectors installed)
  • Size: 48x50x3mm (without connectors)
  • PDFSchematic
  • Eagle design files SCH&BRD
