{"title":"ESP32-S2 Feather with w.FL Antenna Connector","handle":"adafruit-esp32-s2-feather-with-w-fl-antenna","url":"/products/adafruit-esp32-s2-feather-with-w-fl-antenna","description":"This Feather-format development board combines Espressif’s ESP32-S2 Wi-Fi microcontroller with native USB, 4 MB of flash and 2 MB of PSRAM for compact IoT builds. It is well suited to Arduino or CircuitPython projects where you want low-cost 2.4 GHz Wi-Fi and plenty of memory for larger data buffers.The board includes a USB-C connector, LiPoly battery support with built-in charging, battery monitoring over I2C, and a STEMMA QT connector for quick connection to compatible I2C breakouts. It also fits into the wider Feather ecosystem, so it can be expanded with FeatherWings.Native USB lets the ESP32-S2 appear as devices such as a keyboard, mouse, MIDI device or disk drive. Please note that this is a single-core 240 MHz ESP32-S2 board, so it is not as fast as dual-core ESP32 boards, and it does not include Bluetooth support.Features:Processor: ESP32-S2 240MHz Tensilica processorNative USB: Can act like a keyboard/mouse, MIDI device, disk drive, etc!Module certification: Mini module has FCC/CE certificationFlash: Mini module comes with 4 MByte of FlashPSRAM: Mini module comes with 2 MByte of PSRAMAntenna connector: w.FL antenna connector for connecting external antennasAntenna note: This is NOT u.FL!Power options: USB type C or Lipoly batteryBattery charging: Built-in battery charging when powered over USB-CLiPoly battery monitor: LC709203 chip actively monitors your battery for voltageLiPoly battery monitor: State of charge / percentage reporting over I2CReset button: Reset button includedDFU button: DFU (BOOT0) button to get into the ROM bootloaderROM bootloader: USB serial port so you don't need a separate cableSerial debug: Serial debug output pin, optional for checking the hardware serial debug consoleSTEMMA QT: STEMMA QT connector for I2C devicesSwitchable I2C power: Switchable power so you can go into low power modeLEDs: On LEDLEDs: Charge LEDLEDs: User LEDNeoPixel: Status NeoPixelNeoPixel power: Pin-controlled power for low power usageLow power: Low Power friendly!Deep sleep: In deep sleep mode we can get down to 80~100uA of current draw from the Lipoly connectionQuiescent current: Quiescent current is from the power regulator, ESP32-S2 chip, and Lipoly monitorLowest quiescent current: Turn off the NeoPixel and external I2C power for the lowest quiescent current drawArduino: Works with ArduinoCircuitPython: Works with CircuitPythonSpecifications:Product Dimensions: 52.0mm x 22.7mm x 7.2mm / 2.0\" x 0.9\" x 0.3\"Product Weight: 6.2g / 0.2ozA good choice for Wi-Fi sensor nodes, smart home projects, wearables and other compact IoT builds that need Feather expandability and native USB.","vendor":"Adafruit","product_type":"Microcontroller Board","in_stock":true,"options":[],"variants":[{"id":16433,"title":"Default Title","sku":"AF-6282","mpn":"ADA6282","price":41.77,"on_sale":false,"in_stock":true,"available_quantity":98}],"documents":[{"title":"Adafruit ESP32-S2 Feather Guide (PDF)","type":"user_guide","type_label":"User Guide","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDYHwDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--1e077a2bb356f742dcc7f4581b5ba0a6b36db1f6/adafruit-esp32-s2-feather.pdf","link":false,"file_extension":"PDF","file_size":32662878,"description":"Complete user guide for the Adafruit ESP32-S2 Feather in PDF format"},{"title":"Supplier page — adafruit.com","type":"supplier_description","type_label":"Supplier Description","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDYnwDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--02509e1ca47ca907d25404480dc5884769c4d07f/adafruit-esp32-s2-feather-with-w-fl-antenna-adafruit-com-2026-08-17.pdf","link":false,"file_extension":"PDF","file_size":786712,"description":"Snapshot of https://www.adafruit.com/product/6282 (captured 17 Aug 2026)"},{"title":"Adafruit ESP32-S2 Feather Guide (Text View)","type":"user_guide","type_label":"User Guide","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDZHwDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--45cf1cf48fb76cfb650abfca335fef0e0073fe1b/adafruit-esp32-s2-feather.md","link":false,"file_extension":"MD","file_size":411103,"description":"Online text version of the ESP32-S2 Feather user guide"}]}
