SparkFun Atmospheric Sensor Breakout - BME280 (Qwiic)
Overview
The SparkFun 15440 is a versatile environmental sensor breakout based on the Bosch BME280 IC, designed to measure humidity, barometric pressure, and temperature. It features the Qwiic connect system for solderless I2C integration, though it also provides broken-out pins for standard 0.1-inch headers and SPI communication. The board is optimized for low power consumption, drawing less than 1mA during active measurements.
Why Choose This Part
This breakout combines three high-accuracy environmental sensors into a single compact footprint, simplifying BOM and PCB layout requirements. The inclusion of Qwiic connectors allows for rapid prototyping without soldering, while the wide VDD range of 1.71V to 3.6V ensures compatibility with modern low-voltage microcontrollers.
Applications
Key Specifications
Getting Started
Connect the breakout to any Qwiic-enabled development board like the SparkFun RedBoard or use the 0.1-inch pins for breadboard prototyping. Software support is extensive through the SparkFun BME280 Arduino library, which handles the complex compensation formulas required for Bosch sensors. Ensure the power supply remains within the 1.71V to 3.6V range to avoid damaging the IC.
