New Revision of the Scout ESC (Rev 11)
« on: October 30, 2017, 08:47:36 PM »
The first Scout ESC files made public were listed as Version 1, Revision 10. This design was active for most of 2017 but it used VNH2SP30 motor driver chips that are now discontinued by the manufacturer (although they can still be found on eBay and AliExpress).

On October 30, 2017 new files were published on the Downloads page, called "Revision 11." The only difference is the change to VNH5019 motor driver chips, which are the replacements for the obsolete part.

The new chips have all the same specifications as the original except the maximum source voltage has been increased from 16 volts to 24 volts. Doesn't much matter to tankers who are all probably operating well under 16 volts anyway. Both the original and replacement chips are technically rated at 30 amps but the continuous current rating we are giving our PCB is 10 amps continuous per motor without heatsinking. The addition of a heatsink and/or a fan can increase the continuous rating. All designs of the Scout ESC include built-in over-current and over-heat protection so the boards will shut down if you exceed the limits.

Some users had decided to build their own PCBs at home and started with the Rev 10 design, therefore those schematics and files are being left on the Downloads page for reference. For anyone who is just now starting a build, please use Rev 11.
