I noticed the VOXL ESC v2 is out of stock. 😢

Is there any way to use the VOXL with a BLHeli_S compadible ESC?

Also, what was the teams reasoning behind building a ModaAI ESC?

Thank you!

P.S Is there a timeline for restocking them?

Yes, BLHeli ESCs are supported with VOXL Flight and Flight Core. See documentation here: https://docs.modalai.com/voxl-flight-datasheet-connectors/#j1007---8-channel-pwm--4-channel-dshot-esc-output-connector

The ModalAI ESC has a number of advantages for tightly integrated products:
1. Digital / UART communication
2. Closed loop RPM control produces generally more efficient systems
3. Feedback control to detect obstruction or motor failure.
4. Built in USA

We will bring this back in stock once we can source the appropriate MCU. The chip shortage is especially relevant to motor controllers :-(
