4 Hardware Design Files

Currently, there are two versions to the EVMs: version E1 and version A. Version A is functionally and thermally equivalent to E1 except for the following:

  • Device U1 is part of the full release inventory and performs according to the corresponding data sheet
  • Header J4 and shunt H5 are included to optionally open the ALERT bus
  • Lugs MP1 and MP2 are included with associated hardware MP3, MP4, MP5, and MP6

Until all devices have been fully released, this document covers both versions.
