Product details
Overview
SI7050-EVB from Silicon Labs is an evaluation board designed to demonstrate the SI7050-A20 temperature sensor IC in a 3 mm × 3 mm DFN package, featuring ±0.1 °C accuracy from 0 °C to 70 °C, 14-bit resolution, and I²C interface for rapid prototyping of precision thermal monitoring systems in battery-powered IoT endpoints.
For engineers reviewing the SI7050-EVB datasheet, SI7050-EVB pinout, SI7050-EVB application, or SI7050-EVB equivalent, this board enables quick validation of thermal measurement performance, I²C register access, power consumption profiling (195 nA standby), and integration with Simplicity Studio 6 for real-time sensor data visualization and firmware tuning.
Technical Context
The SI7050-EVB implements the SI7050-A20 digital temperature sensor on a compact single-sided PCB with gold-plated test points, onboard pull-up resistors for SDA/SCL, and direct connection to the host MCU via 0.1" pitch headers compatible with Arduino and Raspberry Pi GPIO layouts.
It supports factory-calibrated operation across –40 °C to +125 °C, delivers conversion times as low as 12 ms for 13-bit mode, and includes traceable NIST-traceable calibration data stored in on-chip memory - all accessible through standard I²C commands without external compensation circuitry.

FAQ
What is the primary function of the SI7050-EVB?
The SI7050-EVB is an evaluation board that demonstrates the SI7050-A20 digital temperature sensor IC. It provides immediate access to calibrated temperature readings via I²C, enabling rapid firmware testing, power profiling, and system integration validation without custom PCB design. The SI7050-EVB includes onboard level-shifting and pull-up resistors for seamless interfacing with common microcontrollers.
Does the SI7050-EVB require external calibration?
No, the SI7050-EVB does not require external calibration. The SI7050-A20 sensor on the board is factory-calibrated across its operating range and stores NIST-traceable calibration coefficients in on-chip memory. All temperature calculations are performed internally, and raw I²C register reads return fully compensated values - no host-side compensation algorithms are needed for the SI7050-EVB.
Which microcontrollers are compatible with the SI7050-EVB?
The SI7050-EVB is compatible with any microcontroller supporting standard-mode or fast-mode I²C (100 kHz or 400 kHz), including ARM Cortex-M series, ESP32, nRF52, and Raspberry Pi Pico. Its 0.1" header layout and built-in 4.7 kΩ pull-up resistors ensure plug-and-play connectivity - no additional hardware is required to begin evaluating the SI7050-EVB in your target system.
Can the SI7050-EVB operate from a 3.3 V supply only?
Yes, the SI7050-EVB operates reliably from a single 3.3 V supply, which powers both the SI7050-A20 sensor and onboard logic. The SI7050-A20 itself supports 1.9–3.6 V, but the SI7050-EVB's voltage regulation and I²C level translation are optimized for 3.3 V host interfaces. Using 3.3 V ensures full compatibility with the board's default configuration and eliminates risk of overvoltage damage to the SI7050-EVB.
Where can I find firmware examples for the SI7050-EVB?
Firmware examples for the SI7050-EVB are provided in Simplicity Studio 6 under the "Examples" tab for the SI7050-A20 sensor. These include C-based projects for EFM32, EFR32, and Wonder Gecko MCUs, demonstrating I²C initialization, temperature readout, low-power sleep/wake cycles, and data logging - all tested and validated specifically for the SI7050-EVB hardware configuration.
