Today we’ll be taking a quick look at the Netcomm NB5 ADSL2+ Modem Router which has a date code of 2005/33rd week and a Ethernet/USB based modem/router. We’ve done a teardown of the NB5 ADSL version of this router before so lets how similar they are.
Some screws later and we’re in.
There are a few noticeable parts on the board, firstly the 3300uF 16V capacitor glued to the board (which has come off), a larger than usual 100uH inductor, a fuse with a metallic outer shell and they are using an MC34063 SMPS.

Looks like they’ve upgraded from the 7200 to the 7300 chip compared to the other router and it has a 25MHz and 35MHz crystal as before.

3. Intel 16Mbit Flash

And that’s all.
