The Edimax BR is a family of a small broadband router. Some of them uses MIPS32-based SoC: ADM5120 or RTL8181 and runs MIPS Linux.



The BR6104 is based on the ADM5106 SoC (ARM7TDMI) and Broad Net Technology real-time OS (SOHO.BIN).


The BR6104K is based on the ADM5120P (PQFP). It has one WAN Ethernet port and a 4 port LAN switch. The firmware contains the usual: Linux, Firewall, NAT, dhcp client and server, etc.

BR6104K is actually the same model as BR6104KP, but without USB connector, 48MHz oscillator e.t.c. soldered on the board, and without printer support in the firmware. It is possible to add missed USB parts and have a full BR6104KP model. The instructions are there. Edimax BR6104K/KP is rebranded Sweex LB000021 so PCBs are identical (PCB REV B. uses one DRAM chip, REV A two ones).



The BR6104KP is the same as the BR6104K but has two USB 1.1 master ports that can be used to connect a printer and use it as a print server. Also you can use USB Flash disk for root filesystem (needed patch for usb root device).



The BR6104P is based on the ADM5106 ARM7 SoC.


The BR6104S is based on the Samsung ARM SoC.


The BR6104W is based on the ARM7 SoC.


The BR6104WB is based on the Realtec RTL8181 SoC.


The BR6104WG is based on the WavePlus WP3210 (125MHz MIPS R3000).


The BR6014Wg is based on the ADM5120 (BGA) and has one WAN port and 4 port LAN swith. Additionally, it has a WiFi 802.11G MiniPCI card: AirVast WN360g, which based on the Intersil / GlobespanVirata / Conexant PRISM GT chipset.

NMX-WB04G and ConceptronicC54BRS4 are clones of the BR6104Wg.

Routers's PCB has a place for the second MiniPCI slot, but socket is not soldered.



The BR6104WP is based on ARM7 CPU.


The PS-3205U uses the ADM5120 in BGA package. A SuperIO chip is used to bring out a parallel port, sacificing the access to the 4-Port switch. A MiniPCI socket is also provided.



The EW-7207APg Access Point uses ADM5120. It has a 5-port LAN swith and 802.11g interface.

Board seems to be the same as BR6104Wg with INPROCOMM IPN2220 mini-PCI card inserted.


Serial console is on J2 (Gnd, Tx, Rx) and 3.3V on J3. Pins must be soldered. 115200Bd 8N1

Adding a serial port

On the BR6104K/KP board there is a 8pin connector called JP2 that can be used as serial port. You can connect a serial level shifter (such as the MAX232 familly) to these pins.

Its pins are:

1.RX 2.+3.3V
7.TX 8.GND

Use the 3.3V as supply for the MAX chip, don't use the 5V from the USB. (You wan't to convert to the processors' levels, not the USBs')

Use MAX3232 (pins are same as MAX232) + 4x100nF. Works in range 3V-5V. You can use 3.3V power for MAX3232 from the board.

It is possible to use Siemens mobile phone datacable as converter. And its possible to use solutions like on the 3.3V TTL serial Port of the Linksys NSLU2

Set you terminals' speed to 115200 (8N1). When powering press SPACE three times to get into the boot menu.

== Shell access ==

Some models were observed to display an username/password prompt on the serial console after booting. If username "super" and password "@gogolinux" is entered, it drops to a shell.

My PS-3205U likes more username "edimax" with password "software01". I've found it easily useing "strings AP/mkimg/image/bin/setup". As you can see, the /bin/setup program is the one you talk to at /dev/ttyS1.

== Linux support ==

Edimax recently released the sources to their kernel sources (2.4.18) and other tools such as Busybox.
