Compatibility — read before ordering

What is included
Two printed enclosure pieces only. Heltec board, 18650 cell, battery holder, antenna, wiring and all electronics are not included.
USB and radio caution: Meshtastic documentation notes that the V3/V3.1 CP2102 USB bridge lacks ESD protection and recommends care at the USB-C port; it also notes possible battery-charging issues with USB-C-to-USB-C cables and recommends USB-A-to-USB-C. Follow Heltec/Meshtastic power, battery and antenna guidance.
