Sentinel Receiver Options
-
I was looking at the product listing for the Sentinel and noticed the only RC receiver options listed are ELRS and Ghost Atto. The Sentinels I'm using have Spektrum receivers. Is that no longer an option? Are the ghost atto receivers compatible with a spektrum transmitter and if so is there any additional set-up required to bind them?

@jmltt spektrum will still work, we're just trying to streamline a bit on SKUs here and we have better performance with ELRS (and it's open source so we can mess with it).. Ghost Atto is somewhat to tick the NDAA box.... Internally we use ELRS for the most part now.
I don't think we'll sell Sentinel with spektrum anymore, but the SW/HW is OK to use.
Our VOXL2 hardware has two flavors. Early revs M0054 required an external assembly to handle the bind functionality, latter revs M0154 have it built into the PCBA.
The Ghost is not compatible with Spektrum...
This is a wiring diagram with Spektrum in use for reference on the older M0054 style, which required M0094 external binding assembly (essentially a pull down circuit since the snapdragon smart phone based SoC can't toggle a TX to RX runtime like the little STM32s can).

https://docs.modalai.com/voxl2-d0006/#hw-block-diagram@modaltb We are ordering more Sentinels and we need NDAA compliance so we went with the ghost atto receiver. We wanted to order each vehicle with a controller, but I was confused about what we'd get because I didn't see and ghost atto compatible controllers available for standalone purchase on your site. I found this in the docs though so I'm assuming this is what it ships with, is that right?:
Orqa / GHST

Do all Sentinels now ship out with the M0154?
Would it be possible to retrofit our older sentinels with ghost atto receivers?

Yes new sentinels ship with M0154s. Let me check with the production team about retroffiting
