ZBT WE826-E is a dual-SIM version of the ZBT WE826. The router has the
following specifications:
- MT7620A (580 MHz)
- 128MB RAM
- 32MB of flash (SPI NOR)
- 5x 10/100Mbps Ethernet (MT7620A built-in switch)
- 1x microSD slot
- 1x miniPCIe slot (only USB2.0 bus)
- 2x SIM card slots (standard size)
- 1x USB2.0 port
- 1x 2.4GHz wifi (rt2800)
- 10x LEDs (4 GPIO-controlled)
- 1x reset button
The following have been tested and working:
- Ethernet switch
- wifi
- miniPCIe slot
- USB port
- microSD slot
- sysupgrade
- reset button
Installation and recovery:
In order to install OpenWRT the first time or recover the router, you
can use the web-based recovery system. Keep the reset button pressed
during boot and access 192.168.1.1 in your browser when your machine
obtains an IP address. Upload the firmware to start the recovery
process.
How to swap SIMs:
You control which SIM slot to use by writing 0/1 to
/sys/class/gpio/gpio13/value. In order for the change to take effect,
you can either use AT-commands (AT+CFUN) or power-cycle the modem (write
0/1 to /sys/class/gpio/gpio14/value).

v2->v3:
* Remove the old description of the first time installation and point
the user to the web based recovery system instead (thanks Petr Štetiar).
* Add license to DTS (thanks Petr Štetiar).
v1->v2:
* Use generic board/model detection, updated the match in 01_leds and
02_network (thanks Petr Štetiar).
* Changed the device/target device in the Makefile to match the
compatible-string in the DTS (thanks Petr Štetiar).
* Use the user-space gpio-switch alternative instead of gpio-export in
the DTS (thanks Petr Štetiar).
* Update name of flash node in DTS to the more generic "flash0" (thanks
Petr Štetiar).
* Fix image size in the Makefile (thanks Petr Štetiar).
* Group the wifi-LED together with other devices (thanks Petr Štetiar).
* Updated commit message.
* While the device can be ordered without a modem, I imagine most
devices will be delivered with a modem. I have therefore enabled support
for QMI and Option, so that most modems can be used out of the box.
