I have been following the development of the M0173 COAX connector board. I'm planning to integrate a Rangefinder with my existing setup consisting of VOXL2 compute for reliable height estimation in constrained environments. 

At present I'm using the Image sensors from Starling 1 for my indoor flight requirements. I'm planning to upgrade to the new sensors(AR0144 Tracking, IMX412 - Hires with COAX connectors) with the COAX Cables.

I was checking for development of STM VL53L1CX rangefinder along with Flir Lepton (M0157 -1) board as well. I have few queries on this,

1. Is the development for M0157 - 1 complete and when would it be released? Along with the new [MDK-M0173 product](https://www.modalai.com/products/m0173?variant=48528274456880) would M0157 module also be available for purchase along with that in future?

2. The M0157-1 uses a 8 pin JST-GH type connector [MCBL-00105-1](https://docs.modalai.com/cable-datasheets/#mcbl-00105) for connecting between M0173 and the board itself. The schematics for this cable connector is not yet mentioned? Could you share the schematics?
