Adafruit ESP32-S2 Feather with BME280 Sensor - STEMMA QT

The Adafruit ESP32-S2 Feather with BME280 is identical to the standard ESP32-S2 Feather but with an on-board BME280 temperature, humidity, and barometric pressure sensor at I2C address 0x77. This makes it an instant IoT environmental monitor — just add Wi-Fi credentials and start logging.

Built around the single-core ESP32-S2 at 240 MHz with native USB, 4 MB flash, and 2 MB PSRAM, it includes USB-C, LiPo battery charging and monitoring, a STEMMA QT port with switchable power, and a NeoPixel. Deep sleep current is approximately 80–100 µA.

Key Features

• On-Board BME280 Sensor – Temperature, humidity, and barometric pressure at I2C address 0x77
• ESP32-S2 240 MHz Tensilica – Single-core with 2.4 GHz Wi-Fi (no Bluetooth)
• Native USB – HID, MIDI, mass storage, and CDC serial without an external chip
• 4 MB Flash + 2 MB PSRAM – Large buffers for data-heavy applications
• USB-C – Power, charging, and native USB communication
• LiPo Battery Support – JST connector with charging and battery fuel gauge monitoring
• STEMMA QT / Qwiic – I2C port with independently switchable 3.3V power
• NeoPixel – Addressable RGB LED with controllable power pin
• Ultra-Low Power – ~80–100 µA deep sleep current
• Feather Form Factor – Compatible with FeatherWings
