4.9 GESI LaunchPad-Booster Pack Interface

A GESI Launchpad connectors (J5 and J16) provided in GESI board to interface with Boosterpack modules. BoosterPack plug-in modules shall be plugged in to extend the functionality like wireless connectivity, capacitive touch, temperature sensing, displays and much more. Table 4-7 contains the pin out details of both connectors.

Except BOOST-DRV8848, all other BP interfaces listed below are supported similar to Maxwell EVM:

  • BOOSTXL-ULN2003
  • BOOST-DRV8711
  • BOOSTXL-DRV8301
  • CC3100BOOST
  • BOOST-CC2564MODA

For resistor population option to support specific Boosterpack module, see Figure 4-13.
