smegg99/LoRaptor5LoRaptor is an open-source LoRa P2P mesh messaging platform with custom hardware, firmware and a chat app.
LoRaptor is an open-source printed circuit board by smegg99, from the smegg99/LoRaptor repository on GitHub, published under the MIT licence. It is a 2-layer board of 70 × 40 mm with 40 parts on 77 nets, routed with 835 tracks and 136 vias.
It is built around the ESP32-S3-MINI-1-N8, LDI1117-3.3H and BAT60A, with the PESD5V0S1UB,115-JSM, MF-MSMF110-2 and SMF5.0A among its other parts. Its parts include 11 resistors, 6 capacitors, 6 diodes, 3 connectors and 1 IC. It belongs with the radio and wireless boards and the ESP32 boards of this library.
Open-source LoRa mesh messaging without Wi-Fi, GSM, or Internet.
Custom hardware • Mesh firmware • Flutter chat app
LoRaptor is an open-source LoRa P2P mesh messaging platform built for off-grid communication. It combines a custom hardware node, embedded firmware, and a companion app so a paired phone or computer can send messages through a LoRa mesh network.
LoRaptor uses a compact custom PCB designed around the ESP32-S3-MINI-1 and RA-02 LoRa module, with USB-C, RGB status signaling, and a portable 3D-printed enclosure.
The firmware is built around LoRaMesher for mesh routing and RaptorCLI for device control over BLE or USB.

RaptChat is the Flutter app for managing LoRaptor devices, creating connections, and sending messages over the mesh network.

It measures 70 × 40 mm and has 2 copper layers, 0.8 mm thick.
40 parts, built around the ESP32-S3-MINI-1-N8, LDI1117-3.3H, BAT60A and PESD5V0S1UB,115-JSM. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the smegg99/LoRaptor repository on GitHub, at the commit this page was made from: the board is hardware/LoRaptor/LoRaptor.kicad_pcb and its schematic hardware/LoRaptor/LoRaptor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
