Armament Group
The Armament Group is OpenSkyhawk's reference implementation — the only panel group with real hardware designed. In the A-4E it handles weapons management: the master arm system, the bomb/rocket release system, the gunpod controls, the gunsight, and chaff dispensing.
It runs on a single PanelGroup controller at NODE_ID 1, with a host MCU board plus breakout boards wired over I²C.
Hardware status
| Panel | PCB Status | Firmware Status |
|---|---|---|
| Armament Panel (MCU host) | Schematic complete | Phase 6 stub |
| AWRS Panel | ERC clean (ADS1115 @ 0x48); MODE SEL wiper → A2 not yet routed | Phase 6 stub |
| Misc Switch Panel | ERC clean, DRC unverified (MCP23017 @ 0x22) | Phase 6 stub |
| Gunpod Panel | Planned | Planned |
| Gunsight Panel | Planned | Planned |
| Chaff Panel | Planned | Planned |
Individual panel pages will be added as each panel is designed and built — there's no point in an empty page per panel before the hardware exists.
End-to-end testing in progress
The firmware is a Phase 6 stub: the panel group isn't yet integrated end-to-end through PanelBridge and SimGateway into DCS. This page will be expanded with bring-up and validation notes once that testing completes.
Want to help?
The Armament Group is where the build is most real — schematics exist, the hardware is being brought up. If you want to contribute to firmware integration, PCB review, or a not-yet-started panel (gunpod, gunsight, chaff), start with How to Contribute.
