Power Supply
There are two power supply options for CAPTIVATE-EMC board (see
•
5 V to 20 V DC power through connectors JP1 and JP2. The color of the connectors shows the
polarity, red for positive and black for negative. A TI
all the devices on the CAPTIVATE-EMC.

The CAPTIVATE-PGMR board also can provide 3.3-V power supply to the CAPTIVATE-EMC through
connector J1.
NOTE: Do not connect the CAPTIVATE-PGMR directly to the CAPTIVATE-EMC when a DC power
supply is enabled.

Debug Connector
The 20-pin debug connector J1 is for interfacing to the CAPTIVATE-PGMR board. This connector
provides power, Spy-Bi-Wire, and UART connectivity with the CAPTIVATE-PGMR module.
The Spy-Bi-Wire port lets the user download and debug their own code or the demo code to the
MSP430FR2676 MCU on the CAPTIVATE-EMC board.
The MSP430FR2676 MCU communicates with a dedicated USB HID Bridge MCU located on the
CAPTIVATE-PGMR module using UART to send sensor data and status to the
as part of the sensor design and tuning process.
