{"title":"Adafruit ESP32-S2 Feather with BME280 Sensor - STEMMA QT","handle":"adafruit-esp32-s2-feather-with-bme280-sensor-stemma-qt","url":"/products/adafruit-esp32-s2-feather-with-bme280-sensor-stemma-qt","description":"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.\n\nBuilt 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.\n\nKey Features\n\n\nOn-Board BME280 Sensor – Temperature, humidity, and barometric pressure at I2C address 0x77\n\nESP32-S2 240 MHz Tensilica – Single-core with 2.4 GHz Wi-Fi (no Bluetooth)\n\nNative USB – HID, MIDI, mass storage, and CDC serial without an external chip\n\n4 MB Flash + 2 MB PSRAM – Large buffers for data-heavy applications\n\nUSB-C – Power, charging, and native USB communication\n\nLiPo Battery Support – JST connector with charging and battery fuel gauge monitoring\n\nSTEMMA QT / Qwiic – I2C port with independently switchable 3.3V power\n\nNeoPixel – Addressable RGB LED with controllable power pin\n\nUltra-Low Power – ~80–100 µA deep sleep current\n\nFeather Form Factor – Compatible with FeatherWings\n\n\nAlso Available\n\n\nESP32-S2 Feather (without BME280)\n\nESP32-S2 TFT Feather (with built-in colour display)\n\nESP32-S2 Reverse TFT Feather (display on back for panel mounting)\n\nESP32-C6 Feather (Wi-Fi 6, also has BME280)\n\n\nIdeal For\n\nWi-Fi weather stations and environmental monitors\nIoT sensor nodes with built-in ambient sensing\nBattery-powered data logging with temperature, humidity, and pressure\nCircuitPython and Arduino development\n\n\nPackage Contents\n\n1× Adafruit ESP32-S2 Feather with BME280 Sensor – STEMMA QT\n\n\n\nNote: The ESP32-S2 is single-core and does not support Bluetooth. For dual-core or Bluetooth, consider the ESP32-S3 or ESP32 Feather V2. LiPo battery and USB cable sold separately.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3024,"title":"Default Title","sku":"AF-5303","price":50.58,"on_sale":false,"in_stock":true,"available_quantity":75,"option1":"Default Title"}]}
