The perforation between the USB controller and TMP4719 sensor breakout section is labeled on the bottom of the board on both sides for pin connections. Once the sensor breakout section is detached from the controller section, the user can interface with the board sections by soldering wires or 0.1'' header connectors. With this approach, the user has access to all 10 pins of the device.

The TMP4719 has built-in programmable digital filters to improve noise immunity. However, in especially noisy environments, a bypass capacitor can be placed differentially across the remote channel inputs to make the application more robust against unwanted coupled signals. The sensor breakout section includes 0805 footprints for the user to optionally install filter capacitors (C14 and C21 are default not installed). Additionally, some applications attain better overall accuracy with additional series resistance. The sensor breakout section includes 0805 footprints for the user to optionally install series resistors (R18 and R21 are default 0Ω). See the TMP4719 datasheet for specific recommendations on the filter capacitor and series resistor values.

Note that pullup resistors and protection diodes are on the controller section. Thus, when interfacing with other controller boards, TI recommends to verify that pullup resistors and protection circuitry are present on any controller board for safe and proper functionality.
