I am trying to locate some reversible ESCs (for a sub project). There are some car ESCs out there (e.g., these), but I’m curious if there are other options available.
It sounds as if the BLHeli firmware has a “bidirectional” option available, but I haven’t been able to figure out if any BLHeli compatible ESC can take advantage of this feature, or if it requires particular support. Has anyone looked into this?
I think many ESC’s running BLHeli firmware will work bi-bidirectionally. I have some cheap Velotech ESC’s running BLHeli that I use for bench testing and they do. I just tried the attached setup on the bench out of curiosity and it worked fine using my ESC programming FC (AKA Naze32). Zero throttle ~1500us and +/- 500us.
Use the BLHeli Suite Chrome Configurator? I use Betaflight for passthrough with the Naze32, there is a Chrome Betaflight configurator also or a standalone app for Linux.
Understood. Passthrough would be nice but no go for now. An F3 is a good choice for future proofing because the Naze32 I use for this purpose won’t support the Betaflight version required for BLHeli 32 Suite passthough. I don’t own any BLHeli_32 capable ESC currently but I’m sure I will at some point. F3’s are almost as cheap as a dedicated programmer and you can do them all at once that way.
@lucamax I updated my comment to be more clear to those who don’t use GitHub. An “issue” is a bug/feature tracking tool in Guthub where we keep track of requests for various reasons.
@larsks - I can confirm that all of the BLHeli ESCs support this option. If you want one that’s preconfigured for forward/reverse and thoroughly tested with ArduSub, there are these at Blue Robotics.
Note that ArduSub is normally configured for 1500 µs +/- 400 µs signal.
