Overview

The MSP430™ CapTIvate™ isolation board (CAPTIVATE-ISO) is an add-on board for the CapTIvate Development Kits (MSP-CAPT-FR2633 or CAPTIVATE-FR2676) that allows a way to maintain Spy-by-Wire, I2C, and UART communication between the CAPTIVATE-PGMR and the CapTIvate MCU Board when the MCU Board is powered from an external power source such as a battery or another system.

The CAPTIVATE-ISO board provides low power digital isolation with no shared power or ground between the programmer and the target MCU. Isolation can be useful when performing conducted noise testing or tuning battery power applications.

Features
  • Provides digital isolation for Spy-by-Wire, I2C, and UART
  • No shared power or ground
