The Ubiquiti Airmax M series are based on ar71xx chipset. They include:
|NanoStation M||sectorial 60 deg antenna, high power, 2 ethernet|
|NanoStation Loco M||low cost sectorial 60 deg antenna, 1 ethernet|
|PicoStation M HP||omni directionnal, high power, 1 ethernet|
|Bullet M||other form, high power, 1 ethernet|
|Rocket M||high end, usb|
|PowerBridge M||Rocket M with High power Antenna, 1 ethernet|
|NanoBridge M||device-in-feeder directional dish antenna, 1 ethernet|
Note: For the models with 1 ethernet (nanostation loco m, picostation m hp, bullet m) , use the bullet-m image.
The bullet-m image is the base of the airmax series.
The rocket-m image is the bullet-m with an additionnal usb driver.
The nano-m image is the bullet-m with an additionnal ethernet.
The NanoBridge-m works fine with bullet-m r30919
Power cycle the device while you keep the reset button pushed. Leds will start to blink red and yellow.
Then tftp the image to 192.168.1.20 following the instructions at the Installing OpenWrt via TFTP page.
It is possible to remotely press the reset button on M-series devices by briding the powerlines, Ubiquiti's 1 ampere power injector (the one with LAN LEDs) has a button that you can press that physically closes the reset button circuit. If you have the smaller power injector or a generic one, you can read http://dren.dk/mreset.html for more information about making your own reset button out of it.
serial pins are clearly labeled. GND, SOU, SIN, PWR (3.3V). the PWR connection is not needed when plugged in.

There are also the Unifi and Litestation X which are in the same ar71xx family, but they have different init in the openwrt source. There are 4 models of the Unifi, Unifi AP, Unifi AP LR (Long Range), Unifi Ap PRO, Unifi AP Outdoor
The PowerBridge M, NanoBridge M, AirGrid M are in the airmax M family, but not tested?
