M0155 VOXL 2 Single Image Sensor Micro-coax Adapter
Adapter connecting a single micro-coax tracking or hi-res camera to VOXL 2.
Table of contents
Overview
The M0155 connects one DF-56 micro-coax image sensor module to a VOXL 2 or VOXL 2 Mini camera group. Micro-coax lets the sensor sit anywhere on the airframe, at any orientation, with only a thin coax run back to the compute board, instead of the short flex cables that earlier modules used.

Connectors
VOXL 2 side, J1
J1 is a Hirose DF40C-60DS-0.4V(51) 60-pin board-to-board connector. It mates with VOXL 2 or VOXL 2 Mini camera group connectors J6, J7, or J8.
Only the lower camera slot of the group is wired: its 4-lane MIPI CSI, CCI I2C, reset, and MCLK route to J2. The upper slot’s signals, the SPI, and the 1.05 V, 1.8 V (VREG_S4A), 3.3 V, and 5 V rails are not connected. RESET_UPPER_SHARED/N (pin 26) is routed to J2 as SYNC.

Sensor side, J2
J2 is a Hirose DF56C-26S-0.3V(51) 26-pin micro-coax receptacle. It mates with any ModalAI micro-coax sensor module through an MCBL-00084 cable: M0161, M0166, M0186, and similar.

Software
The sensors connected through the M0155 are supported by voxl-camera-server and publish over the Modal Pipe Architecture like any other camera. Select the sensor with voxl-configure-cameras, see Configure Cameras. The Micro-Coaxial User Guide covers cable routing and handling.
