From the project

Meshtonic H4M Companion — ESP32-S3 carrier for PortaPack H4M / Mayhem with multi-slot LoRa and standalone Meshtastic

Meshtonic H4M Companion v2 is a custom carrier board and firmware stack for a Seeed XIAO ESP32-S3 Plus that docks to a HackRF + PortaPack H4M (Mayhem) and can also run as a standalone Meshtastic mesh node.

Repository: github.com/Josephrp/meshtonic (formerly Meteor-On-Mesh)

The two ESP32 firmwares are mutually exclusive — flash one or the other depending on whether you are using the board docked or as a mesh node.
