VOXL ESC power
the first question is how to power the ESC? is there any specific port on the Voxl flight deck and a cable by which I can power the ESC? or should we go with a PDB to do so as per usual?
Also, what capacitor do you recommend for powering the Voxl ESC v2?
Regarding the hardware connections, in case I wanted to use the port J1007 - 8-Channel PWM / 4-Channel DShot ESC Output Connector of the flight deck with a cable MCBL-00004 to the PWM Breakout Board, do you sell any cable to connect PWM Breakout Board to the Voxl ESC v2?
Hi @mbahrami ,
Our flight deck is optimally suited towards PWM based ESCs since it incorporates our Flight Core design with PWM control easily accessible. So I am trying to find out from our SW team which UART port is best for the ModalAI 4-in-1 ESC Digital Comms port in this config.
Regarding powering your ESCS, the way we have our power module designed is to allow a "pass-through" of the 2S-4S VLIPO battery voltage (the ESC is rated to 4S). So, you would use 1 battery, connect it to our Power Module VLIPO input which powers the Flight Deck as shown in the Technical Docs section:
And then on the "output" of the VLIPO path on the Power Module, you can use that to power the ESC. https://docs.modalai.com/power-module-v3-datasheet/
We have not had any need for any extra capacitors in our systems, so we do not have any recommendation there. I would test first without added parts/weight, and you might find you are very well off. We go to great lengths to design really robust power delivery systems.
When I get an answer from SW about using the ESC UART port, I'll respond again.
Default UART for the ESC driver is here:
No flow control.... really just need GND, Rx, Tx
