3) Case (top)
Individual modules are well protected although the interface PCBs are exposed. The shipped weight of an Avalon 3 is 4.5kg and dimensions of the shipping
box are 490 x 180 x 150mm.

4a) Configuration (TL-WR703N) (top)
The interface board has been updated to allow for up to 4 modules and interface boards to be daisy chained off one USB port.
Wiring:
- The first module's interface board should have one 4 pin cable connected to the 4 pin to micro
USB adapter, which is then connected to the micro USB to USB cable. The USB cable can plug directly into the host controller or into a USB hub if
more groups are being chained on one controller. The second module's interface board should have its 4 pin cable plugged into the first board and
itself. The third should plug into the second and itself, and the fourth into the third and itself. - Each of the four boards must have a different jumper arrangement - either both off, both on, the left one on or the right one on. It doesn't matter
which board has which as long as they are unique. - Plug in a network cable from the WR703N to your router, and power it on.
Configuration:
- Power on the power supply using its switch at the back.
- Make sure or your router's subnet is 0, ie 192.168.0.x. If not then change it to 0, this is just temporary. ***If this is not possible, see below***
- Using a browser, navigate to 192.168.0.100 - this goes to the WR703N's configuration page.
- Login using "root" as the username.
- Navigate to Network -> Interfaces -> WAN -> Edit.
- Change protocol to DHCP and click "Save & Apply".
- Using a browser, navigate to your router and find the IP it has assigned the WR703N and navigate to that IP.
- Navigate to the page Status -> Miner Configuration. Enter your pool information in the below format.
- Navigate to the page "Miner Status" to check mining has started.
- You can then change your router subnet back to whatever you are used to using.
Alternative Subnet Change:
- Unplug your computer from all internet sources.
- Plug in an ethernet cable from the WR703N to your computer.
- Navigate to Control Panel -> Network and Sharing Centre -> Change Adapter Settings.
- Right click on your ethernet adapter -> Properties.
- Click on "Internet Protocol Version 4" and click properties.
- Select "Use the following IP address" and enter the following:
- IP Address: 192.168.0.1, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.0.100.
- Plug in an ethernet cable from the WR703N to you router.
- Restart the configuration instructions as above.

5) Troubleshooting (top)
| Problem | Solution |
| What temperatures should I aim for? | - Try to achieve <60C for long lifetimes. Temperatures should not be let to rise above 65C. |
| How can I tell what firmware version I have now? | - Navigate to Status -> Cgminer API Log and look at "Firmware Version". |
| Where.can.I.find.the.latest.firmware.for.the.WR703N? | - Download the latest firmware from here (the WR703N.bin). |
| Where can I find the latest firmware for the Pi? | - Download the latest firmware from here (the sdcard-vfat-ext4.img). |
| How do I install the latest firmware? | - Download firmware as above. Navigate to System -> Upgrade and click "browse". Select the downloaded file and click "Flash image". Do NOT interrupt this process or you will brick the unit. |
