1.7.2 Revision B

The second production revision of the LAUNCHXL-F280049C was released in x. This revision can be identified by the "MCU025B" silkscreen labeling on the back side of the EVM. The fixed issues and added enhancements from the first revision (A) are described below.

Fixed issues:

  • Fixed primary side power contention issue on USB Isolation IC, ADUM3160 (U3). See Section 1.7.1 for description of issue.
  • Fixed J6 and J8 header errors described in Section 1.7.1

Enhancements:

  • FSITXD1, FSIRXD1, and 3.3V power signals have been added to the expanded 2x5 connector J11
  • XDS110 MCU (U2) TM4C129x device replaced with MSP432E401 device. Form and function have not been changed with this in any way.
  • Precision reference (U11) connected to the XDS110 MCU (U2) has been removed and VREFA+ (pin 9) has been directly connected to VDDA (pin 8)
