LILYGO® TTGO LoRa32 V2.1_1.6 Version 915Mhz ESP32 LoRa OLED 0.96 Inch SD Card Bluetooth WIFI Wireless Module ESP-32 SMA Q211
LILYGO® TTGO LoRa32 V2.1_1.6 Version
At the TTGO LoRa V2.1 ,we added the SMA and IP5306 to the board, which allows it to do more things.
In terms of the power switch, LILYGO has changed the switching interaction mode.
The added SMA antenna can enhance signal transmission.

Dev board return policy
Development boards are specialty items that generally cannot be resold on return, especially if the firmware has been flashed. Defective boards can be replaced or returned for refund within 30 days of purchase. Non-defective boards can be returned in the same time frame if in like-new condition with a 20 percent restocking fee applied. If the board has had altered firmware or became bricked due to a non-standard firmware flash, the board may not be eligible for return.
Easy to configure with metastatic! So many possibilities for sensors,etc.
I quite like the little LoRa Radios I purchased, they all powered on when tested and were well packed. Though i do wish Lilygo made it a bit easier to find proper detailed documentation on these things, a link to a PDF or a little spec sheet would have been nice as they do require a battery and some ancillary parts to work
Not a huge complaint but was a slight annoyance having to google for the correct model number
