The onboard antenna is selected by default, and you can switch antennas in your code via the RF switch.The board is ready for modern ESP32-S3 workflows, with CircuitPython support and shipping CircuitPython code available, plus Arduino 2.0.3 or later, ESP-IDF and an early MicroPython port. It also includes a STEMMA QT connector for easy I2C expansion.Features:32Bit Dual Core 240MHzRISC-V ultra low power core2.4GHz WiFi - 802.11b/g/nBluetooth® 5, BLE + Mesh16MB QSPI Flash8MB Extra QSPI PSRAMUSB-C ConnectorUSB ESD protectionReverse USB back-feed protectionJTAG Pins + USB Serial JTAG2x 700mA 3.3V LDO RegulatorUltra low deep sleep currentSTEMMA QT connector powered by LDO1Low Power RGB LED5V presence detectionLiPo Battery ChargingMicroBlade LiPo connectorPower (red), Charge (orange) LEDs27x GPIO broken outCastellated HeadersNEW I2C Battery Fuel GaugeNEW 3D High Gain Antenna AND u.FL connectorCompatible with TinyPICO, TinyS2 & TinyS3A strong choice for portable ESP32-S3 builds, WiFi/BLE projects, battery-powered sensors and CircuitPython or Arduino development.","vendor":"Adafruit","product_type":"Development Board","in_stock":true,"options":[],"variants":[{"id":16438,"title":"Default Title","sku":"AF-6398","mpn":"ADA6398","price":63.26,"on_sale":false,"in_stock":true,"available_quantity":86}],"documents":[{"title":"ProS3D Main Features Diagram","type":"mechanical_drawings","type_label":"Mechanical Drawings","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDdnwDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--6d4e1830904a7754c062c1e43018a0ed509f3fa3/main_features_pros3d.pdf","link":false,"file_extension":"PDF","file_size":266550,"description":"Feature and layout diagram for the Unexpected Maker ProS3D board"},{"title":"Supplier page — adafruit.com","type":"supplier_description","type_label":"Supplier Description","url":"https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDd3wDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b4909d76be269cd4435e608b5b80b65c71d50e29/pros3-d-esp32-s3-by-unexpected-maker-adafruit-com-2026-08-17.pdf","link":false,"file_extension":"PDF","file_size":768507,"description":"Snapshot of https://www.adafruit.com/product/6398 (captured 17 Aug 2026)"}]}
