how do you flash new firmware? I want to install the latest meshtastic with meshtastic flasher tool, but won't go into boot mode

OK, this is the 3rd time I've tried to answer this question. If Amazon doesn't want me to answer, they should probably stop asking. The most reliable way I have found to flash the firmware is to use the python tool ,ESPtool, that works with the ESP32 chip. You can find instructions on meshtasticDOTorg under Getting Started > Flashing Firmware > CLI Script - ESP32 Obviously you need to make sure you are writing the correct firmware.

What is the overall board dimensions?

Please check the video there to show the product size.

What is the typical range for one of these devices? More then a mile?

My three boards are setup with SoftRF firmware not Mestastic but the hardware is the same. They are used to track gliders, the longest range when testing was just over 20 miles. But the unit was at 3000 ft. They are line of sight devices if the terrain is blocking it will be much shorter.
