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.
