Squonk informs us that he’s reverse engineered the layout of the small TP-Link TL-WR703N 802.11n WiFi router using EagleCad. He writes: “Unlike what it is marketed for, the TP-LINK TL-WR703N is not a “3G travel router”: it does not include a 3G modem at all, it simply means that the firmware support external USB 3G modems! Despite this shortcoming, at less than $23, this device is the cheapest Wi-Fi router you can get west of the Pecos River!” Inside he found an Atheros AR9331 chipset with Atheros AR7040 400 MHz MISP24kc CPU, integrated 802.11n 150 Mbps (130 Mbps real) Wi-Fi with 20 dB (100 mW) output power, 4 MB of serial (SPI) Flash memory, 32 MB of DDR SDRAM, a USB 2.0 host port and other goodies.
