Heltec WiFi LoRa 32
ESP32-S3 with an SX1262 LoRa radio and a small OLED (V3/V4) — the go-to Meshtastic mesh board. Long-range, low-power, and it runs the stock Meshtastic firmware out of the box.
A third-party board by Heltec Automation — documented here and credited to its maker; source it wherever you like.

How the stack uses it
Run it as a Meshtastic node and talk to it over the protobuf StreamAPI — Cyber Controller reads the node list (names, SNR, battery), channels, and text, and sends text back. As an S3 it flashes over native USB — no CH340 driver needed.
