    Now you receive T-Beam V1.1! Marking on the silkscreen: T22_V1.1 20191212. This new revision has a mosfet for reverse polarity protection and a red LED connected to IO4. If the LED is not used in software it will glow dimly. The blue charging LED moved to the left to the red LED, so in my case it's now obstructed by the OLED display. Check if you want to see it in your case! GPS antenna has adhesive on the top so you can stick it inside your housing. The micro-USB plug is soldered straigt but the WiFi-antenna was bend before soldering and thus couldn't be fixed and the WiFi signal strength is a bit lower. The GPS battery is a 1mAh rechargeable lithium from Seiko MS412FE and was charged to 2.7V when the board arrived, it is further charged when the board is powered. Shipping from UK was within 1 week as usual.

    Device received is revision 8 (latest is rev 10 from aug 2019), comes preflashed with SoftRF release 1.0-rc7. Just add an 18650 battery (careful about polarity, clearly marked on the board), charge it over USB and you are ready to go. Interna WiFi access point allows configuring the firmware (password 12345678, connect to 192.168.1.1), notably enabling BT and NMEA output over Bluetooth to make it a perfect complement to xctrack, xcsoar and lk8000 glider software running on a tablet or smartphone. GPS is a uBlox neo-6m, not the very latest (there is another more expensive board sold with an 8m) but sufficient for my purposes. A useful addition is a BMP280 barometric pressure sensor on the I2C port (the firmware recognizes it at boot, just like bmp085, bme280, and mpl3115a2 - probably bmp180 as well). You can also add a small 0.96 inch OLED display, which will display the glider ID, protocol, and rx/tx counters. The firmware sources and other project files are available on https://github.com/lyusupov/SoftRF - looking forward to add some bells and whistles :-)

    j’utilise cette carte pour réaliser des balise de signalement électronique pour Drone et je doit dire que elle fonctionne à merveille pour le moment

    Working great! :) One seems just a little slower to get a GPS Fix than the other.. I will test this better in the next few days

    Deveice received has this marking on the silkscreen: T22_V1.0 20190612. Unfortunately the backup battery for the GPS was already depleted when the module arrived (1,7 V, see picture. should be ~3V). Because of this the GPS takes long to find a fix, even when it was only turned off briefly. The micro-USB connector is soldered at an angle, so the housing needs to be modified to fit the USB cable. Shipping from UK was fast (1 week) but the package was not protected. Only the module with pinheaders inside an ESD bag, the packaging was only a thin plastic envelope. Thus the WiFi-antenna was bend and the GPS antenna was loose.
