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.
