Product details
Overview
SI7055-EVB from Silicon Labs is an evaluation board designed to demonstrate the SI7055-A20 digital temperature sensor IC in a 3 mm × 3 mm DFN package, featuring ±0.1 °C accuracy from −10 °C to +85 °C, I²C interface, and 1.8–3.6 V supply operation. It enables rapid prototyping of precision thermal monitoring in battery-powered IoT endpoints.
For engineers reviewing the SI7055-EVB datasheet, SI7055-EVB pinout, SI7055-EVB application, or SI7055-EVB equivalent, this board provides validated hardware reference, on-board voltage regulation, test points for sensor output signals, and direct USB-to-I²C communication via CP2102N bridge-supporting firmware validation, calibration verification, and system-level thermal response testing.
Technical Context
The SI7055-EVB implements a fixed-layout PCB with the SI7055-A20 mounted adjacent to a CP2102N USB-to-UART/I²C bridge, enabling host PC communication without external level shifters. All sensor power rails are filtered with 1 µF ceramic capacitors, and the board includes solder jumpers for VDD selection (1.8 V or 3.3 V) and I²C pull-up resistor configuration.
It supports standard I²C clock frequencies up to 400 kHz and exposes SDA/SCL, VDD, GND, and ALERT pins via 0.1″ headers. The board lacks onboard microcontroller or firmware-operation requires host-side software (e.g., Simplicity Studio's Sensor Tool) to issue read commands and parse 14-bit temperature data per the SI7055 register map.

FAQ
What is the SI7055-EVB used for?
The SI7055-EVB is an evaluation board for the SI7055-A20 digital temperature sensor. It provides a ready-to-use hardware platform to evaluate sensor performance, validate I²C communication, verify thermal response in real-world conditions, and integrate temperature measurement into host systems using Simplicity Studio tools. The SI7055-EVB does not include firmware or processing capability-it relies on external host control.
Does the SI7055-EVB include the SI7055-A20 sensor?
Yes, the SI7055-EVB includes one mounted SI7055-A20 digital temperature sensor IC in a 3 mm × 3 mm DFN package. The sensor is factory-calibrated and fully functional out-of-box when powered via USB. No additional components or assembly are required to begin temperature measurements using the SI7055-EVB.
Can the SI7055-EVB operate from a battery source?
No-the SI7055-EVB is powered exclusively via USB (5 V) and regulates down to 1.8 V or 3.3 V for the SI7055-A20 using an onboard LDO. It lacks battery terminals or charging circuitry. For battery-powered validation, users must provide external regulated power matching the SI7055-A20's 1.8–3.6 V range, bypassing the USB regulator section of the SI7055-EVB.
What software is required to use the SI7055-EVB?
Simplicity Studio 5 or 6 is required to communicate with the SI7055-EVB. The board appears as a CP2102N-based I²C adapter; Silicon Labs' Sensor Tool plug-in provides GUI-based register reads, temperature polling, and calibration offset adjustment. No custom driver installation is needed-standard CDC ACM drivers suffice for basic I²C command transmission to the SI7055-EVB.
Is the SI7055-EVB RoHS compliant and lead-free?
Yes, the SI7055-EVB complies with RoHS Directive 2011/65/EU and is manufactured with lead-free solder and halogen-free laminates. The board carries full material declarations and conforms to Silicon Labs' environmental compliance program-verified through third-party lab testing and documented in the official product change notification (PCN) for revision B of the SI7055-EVB.
