 I would suggest that you try how it fits into the PET tube before soldering it to the PCB. Make sure that the battery is attached since this will be a really tight fit.

 -------------
 
-* Support either an ESP8266 or ESP32C3 board
+* Support either an ESP8266-d1-mini, ESP32-mini or ESP32C3-mini board (see :ref:`hardware`)
 * Operates in two modes gravity monitoring and configuration mode
 * Gravity mode is comparable to how the iSpindle works when collectintg data
 * Configuration mode has a modern HTML5 based web UI. No need to start the access point to change settings
