Queries about development #3

Closed Npidys closed 7 months ago

Npidys commented 1 year ago

I have a few queries about developing an ESC similar to this, as a part of a student project:

  1. What was the battery voltage when you tested this ESC at 40A? Is it limited to 3S/4S ?
  2. The MP1907 drivers are currently out of stock. Can they be replaced with MP1907A, in your opinion? The electrical quantities look mostly the same to me. https://www.monolithicpower.com/en/mp1907a.html - MP1907A

Thanks!

Hi,

  1. It is tested with both 4s and 6s. Check the maximum ratings which is clarified here: https://github.com/ckflight/ESC_BLDC_HARDWARE/issues/1

  2. Yes it looks exactly the same.

You are welcome. Regards.
