> i’m having this board: TTGO ESP32-Paxcounter LoRa32 V2.1 1.6 Version 868MHZ

To prevent further confusion, that is not the real name of your board.  
The correct name of the board is **TTGO LoRa32 V2.1** -1.6 like shown below.

![6](https://www.thethingsnetwork.org/forum/uploads/default/original/3X/6/d/6d4a3827c8609d0d0bb79fb8044b85d80b463033.png)

LilyGO is not very consistent in their naming of this board series.  
The board’s model name is actually TTGO LoRa32, also referred to as ‘T3’ which is confusing.  
V2.1 is the version of the model, while 1.6 is the revision number of this model version. Again confusing due to the double ‘version’ number. ‘TTGO LoRa32 V2.1 rev1.16’ would have been easier to understand.

[ESP32-PaxCounter](https://github.com/cyberman54/ESP32-Paxcounter) is the name of software that came probably installed on it.  
There is a dedicated topic for PaxCounter: [Wifi/BLE Paxcounter Project with ESP32 boards](https://www.thethingsnetwork.org/forum/t/wifi-ble-paxcounter-project-with-esp32-boards/13175)
