Heltec WiFi LoRa 32
ESP32-S3 with an SX1262 LoRa radio and an OLED — the Meshtastic mesh target. Cyber Controller speaks its Meshtastic protobuf directly.
By Heltec Automation — a third-party board Cyber Controller targets. It’s not ours and not for sale here; this page documents what it is and how the stack uses it.

Role in the stack
The LoRa/Meshtastic node Cyber Controller talks to over the protobuf StreamAPI — it reads the node list (names, hardware, SNR, battery), channels, and incoming text, and sends text from a dedicated panel. Built dependency-free with a hand-rolled protobuf codec.
Flash and control it with Cyber Controller. Every board’s first real-silicon flash is validated before it’s ever claimed to work.
