The COM connector interfaces with TI's MPU platforms, such as the AM335x evaluation module (TMDXEVM3358).

Note:
  • All I/Os for the COM connector are at 1.8 V.
  • Some components must be removed (DNI) and R2 must be populated on the CC256XCQFN-EM to use to use the COM connector with the AM335x evaluation module.
  • EM1, EM2, U2, U3, U4 must be unpopulated (removed).
  • R2 (0 Ω) must be populated.
  • More information on the hardware changes required for COM connector is in the Dual-Mode Bluetooth CC2564C Evaluation Board User's Guide and the CC256XCQFN-EM board design files (schematics and bill of materials).
