TOTOLINK N6的改造及相关资料

a234712524

totolink n6，市场价30多，体积小很适合携带。但是没有USB口。原始拆机图有人发过了，就不发了。见这里
配置：
CPU：Ralink RT5350F
RAM:WINBOND W9864G6JH-6  8m
flash:eon F80-100hcp   1m
自带TTL接线端，接法是从电路板上的J4标识算起，分别是GND,TXD,RXD,Vcc，波特率是57600.
这个路由器能够改的有添加网口，能很方便地改SMA，因为有预留的空位。能改FLASH和RAM，但是固件还很少，意义不大。无法加USB，因为芯片引脚没有引线出来.下面是改造过程需要注意的一些东西。

加网口：
网口很好找，只要大小相同即可，网络变压器型号为MNC H1201DG，不同牌子的网变针脚定义不一定一样，需要注意。网变下面空焊处是4个电阻3个电容。电阻阻值为49.9欧。电容大小未知（似乎是12nf？）。顺序是：从电路板上电解电容的标识C13那边开始算起，分别是电阻、电阻、电容、电容、电阻、电阻、电容。要注意，虽然左右两边排列顺序一样，但是有两个位置的电容在电路中的作用是不一样的。最后加上缺少的LED灯和LED灯旁边的电阻。下面上张改造失败的图。

改SMA：


如图所示。不知道旁边空焊的那么多元件是什么作用的呢？

改flash和ram：
flash更换为eon EN25Q64-104HIP后原版固件就能识别，难度也不大。
拆下内存和CPU看过后，发现内存第36脚也就是A12地址线是有引线出来直接到CPU的，但是本人在更换内存时不小心报废了整块板，所以能否成功尚不可知。
也许有人想知道是否需要改地址线电阻，我这里已经无法验证了，如果需要改动的话，看资料可能是在如下红框位置
