When troubleshooting serial bus communications like I2C, UART, or SPI, it can be handy to disconnect a chip select or data line to isolate external devices. Once isolated, the data can be viewed on a logic analyzer or oscilloscope to determine if the SPI or UART signal outputs are really connected to inputs or when examining the effects of multiple pull-up resistors on I2C. The Feather Isolator was designed to individually disconnect a Feather's pin with a switch to help with the troubleshooting effort.
