 We are using HelTec Automation Wirelsess Sticks ESP32 Dev-Boards.
 
-### PinOut
-
-The PinOut of our version 3 modules can be found here:  https://docs.heltec.org/en/node/esp32/dev-board/hardware_update_log.html#wifi-lora-32-hardware-update-logs
-
-![PinOut](https://resource.heltec.cn/download/Wireless_Stick_V3/HTIT-WS_V3.png "PinOut")
-
-### License
-
-For some parts of the Heltec board you need a ["license"](https://docs.heltec.org/general/view_limited_technical_data.html#esp32-lora-series).
-
-### USB-C
-Our HelTec Automation Wirelsess Sticks ESP32 Dev-Boards already have USB-C. But they do not support Power Deliver (PD). If your computer tries to do PD, just plug a cheap USB hub between the board and your computer.
-
-### Arduino IDE
-
-HelTecs GitHub repo can be found here: https://github.com/HelTecAutomation/Heltec_ESP32
-
-I had to install VCP Drivers, first: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads
-
-You can add their Board Manager to the boards managers URLs: https://github.com/HelTecAutomation/Heltec_ESP32/blob/master/library.json and find their libraries in the IDE (Sketch -> Include Library -> Manage Libraries... Search for "heltec esp32").
-
-> These boards are already *V3* boards, so be careful selecting the right board and port (VCP).

-
-### Install esptool
-
-Esptool is a Pyhton program to flash ESP32. As it's a Pyhton tool you can install it using `pip`:
-
-```sh
-pip install esptool
-```
-
-### Find the port 
-
-Usually you can find the used port using `esptool.py`:
-
-```sh
-esptool.py write_flash_status --non-volatile 0
-```
-
-#### Using MicroPython
-
-Download the firmware: https://micropython.org/download/
-
-Flash it using `esptool`: https://micropython.org/download/GENERIC_S3/
-
-
-```sh
-esptool.py --chip esp32s3  write_flash -z 0  ~/Desktop/GENERIC_S3-20220117-v1.18.bin
-```
