VOXL SDK

VOXL SDK is the open-source software stack that ships on every VOXL platform — the same SDK runs on VOXL 2, VOXL 2 Mini, and all ModalAI development drones. It bundles the Modal Pipe Architecture (MPA) core services, SDK libraries, inspection tools, and build environments you need to develop your own software on VOXL hardware. Source code and build instructions live at gitlab.com/voxl-public.

How the SDK fits together

Everything on VOXL moves through the Modal Pipe Architecture (MPA): small services that publish and subscribe to named pipes. Which services boot is decided per-SKU by voxl-configure-mpa — solid boxes below are enabled by default on current drones, dashed boxes are optional features. FPV SKUs ship video through the voxl-vtx / voxl-osd chain, with voxl-rc-server bridging RC on the ground side; drones with an IP link use voxl-streamer instead.
