The BMP280 is a compact barometric pressure and temperature sensor module for Arduino, ESP32, Raspberry Pi, and other microcontroller projects. It is ideal for weather stations, altitude measurement, drones, environmental monitoring, and data logging.

Measures barometric pressure and temperature
Supports both I2C and SPI communication
Compact GY-BM280 breakout module
Great for Arduino, ESP32, Raspberry Pi, and STM32 projects
Perfect for weather, altitude, and environmental sensing

Quick Start

Connect power

Connect VCC to 3.3V and GND to GND.

Connect I2C pins

Connect SCL to A5/SCL and SDA to A4/SDA on an Arduino Uno.

Install library

Use the Adafruit BMP280 library or another compatible BMP280 Arduino library.

Check address

Default I2C address is usually 0x76. Pull SDO high to use 0x77.

Please note: This is the BMP280 version. It measures pressure and temperature only, not humidity.

PinsVCC, GND, SCL, SDA, CSB, SDO

Please note: Do not connect this 3.3V module directly to 5V unless your setup uses suitable level shifting.

Getting Started

Wire VCC and GND

Connect VCC to 3.3V and GND to GND.

Wire I2C

For Arduino Uno, connect SCL to A5 and SDA to A4.

Leave CSB and SDO unconnected

This keeps the module in default I2C mode with address 0x76.

Install a BMP280 library

Install the Adafruit BMP280 library through the Arduino Library Manager.

Upload example sketch

Open a BMP280 example sketch, select your board and port, then upload.

Wiring: VCC → 3.3V, GND → GND, SCL → A5/SCL, SDA → A4/SDA.

What's Included

Please note: This module is best for pressure, temperature, and altitude-based projects.

Common Questions

Is this a BMP280 or BME280?

This is a BMP280. It measures pressure and temperature only. It does not measure humidity.

Can I use this with Arduino?

Yes, it works with Arduino boards using I2C or SPI. For Arduino Uno I2C, use SDA on A4 and SCL on A5.

Can I use this with ESP32 or Raspberry Pi?

Yes, it is compatible with ESP32, Raspberry Pi, STM32, and other 3.3V microcontroller platforms.

Can I connect it to 5V?

This is a 3.3V module. Do not connect directly to 5V unless using proper voltage level shifting.

Please note: If your code cannot find the sensor, check the I2C address. It may be 0x76 or 0x77.

Why buy from NZN

International prices. None of the international wait.

We're a small Kiwi-owned shop, and we stock the same boards and parts you'd usually order from overseas, for about the same price. The only real difference is they ship from Te Awamutu, so you get them in a few days instead of waiting weeks.

Run by Kiwis, here in Te Awamutu

We're NZ owned and operated, and every order is picked, packed and sent from our place in Te Awamutu, Waikato.

Get it in days, not weeks

Order before 8am and it ships the same day, otherwise within 24 hours guaranteed. No waiting three to six weeks for a parcel to crawl over from overseas.

Low prices are the goal

As a maker myself, I want New Zealand to have a genuine low-price local option for electronics, not overpriced shelves or a long wait on an international parcel.
