{"title":"Thing Plus ESP32 WROOM (U.FL)","handle":"sparkfun-thing-plus-esp32-wroom-u-fl","url":"/products/sparkfun-thing-plus-esp32-wroom-u-fl","description":"Built around Espressif’s ESP32-WROOM-32UE module, this Thing Plus board gives you a compact foundation for connected projects that need WiFi, Bluetooth and a flexible antenna setup. The onboard U.FL connector lets you attach a suitable external antenna for installations where a PCB antenna is not ideal, such as enclosures or builds needing more antenna placement flexibility.The board follows the SparkFun Thing Plus form factor and is compatible with the popular Adafruit Feather footprint. It breaks out 21 multifunctional GPIO pins on standard 0.1-inch spaced headers, with access to ESP32 peripherals including capacitive touch, SPI, UART, I2S audio and I2C.For expansion and power, it includes a solderless Qwiic connector for plug-and-play I2C modules, a micro-B USB connector for power and programming, and a 2-pin JST connector with charging circuitry for an external LiPo battery. It can be programmed like a standard microcontroller, including via the Arduino IDE with the updated ESP32 Arduino Core.Supporting resources from SparkFun include the schematic, Eagle files, hookup guide, board dimensions, ESP32-WROOM-32UE datasheet, ESP32 technical reference manual, Thing Plus comparison material, Qwiic information and GitHub hardware repo.Features:WiFi (802.11b/g/n): Dependable 2.4GHz transceiver for local network and cloud connectivity.Dual-Mode Bluetooth®: Support for both Classic Bluetooth and Bluetooth Low Energy (BLE).Hardware Encryption: Built-in acceleration for AES, SHA2, ECC, and RSA-4096 to keep your data secure.Solderless Qwiic Connector: Seamlessly integrate the board into SparkFun's ecosystem of plug-and-play I2C sensors, actuators, and displays.Integrated Power Management: Features a micro-B USB connector for power and programming, plus a 2-pin JST connector and built-in charging circuit for an external LiPo battery.Status Indicators: Includes a yellow charge LED and a blue status/test LED for quick visual feedback.Programming: Can be programmed like a standard microcontroller, including using the Arduino IDE with the updated ESP32 Arduino Core.Specifications:Module: ESP32 WROOM (U.FL) ModuleModule part: ESP32-WROOM-32UE module from Espressif™GPIO: 21 Multifunctional GPIOHeader spacing: standard 0.1-inch spaced headersADC channels: Up to thirteen 12-bit ADC ChannelsDAC channels: Up to two DAC channelsPWM outputs: Up to sixteen PWM outputsCapacitive touch pins: Up to eight capacitive touch pinsSPI busses: Up to three SPI Busses (only one is configured by default in the Arduino IDE)I2S audio: An available I2S Audio OutputI2C buses: Up to two I2C Buses (only one is configured by default in the Arduino IDE)UARTs: Up to two UARTs (only two are configured by default in the Arduino IDE, one UART is used for bootloading/debug)Form factor: Thing Plus (or Feather) Form-FactorDimensions: 2.55\" x 0.9\"Mounting holes: Four Mounting HolesScrew compatibility: 4-40 screw compatiblePTH pins: 28 PTH PinsUSB connector: micro-B USB ConnectorBattery connector: 2-pin JST Connector for a LiPo Battery (not included)Qwiic connector: 4-pin JST Qwiic ConnectorCHG LED: Yellow battery charging indicator13 LED: Blue status/test LEDButton: 0Button: ResetAntenna connector: U.FL ConnectorOperating Voltage: 2.3 to 3.6 VDeep sleep current: 2.5 µA deep sleep currentAverage operating current: 80 mA average operating currentOperating Temperature: -40 to 85 °CMicroprocessor: Xtensa® Dual-Core 32-bit LX6 Microprocessor (up to 240MHz)ROM: 448KB of ROMSRAM: 520KB SRAMFlash storage: 16MB of Embedded SPI flash storageWiFi: Integrated 802.11b/g/n WiFi 2.4GHz transceiverBluetooth: Integrated dual-mode Bluetooth (classic and BLE)Encryption: Hardware-accelerated encryption (AES, SHA2, ECC, RSA-4096)A handy choice for IoT prototypes, sensor nodes, data streaming projects and Feather/Thing Plus builds that need Qwiic expansion and an external antenna connection.","vendor":"SparkFun","product_type":"Microcontroller Board","in_stock":true,"options":[],"variants":[{"id":15867,"title":"Default Title","sku":"SF-WRL-17381","mpn":"WRL-17381","price":47.05,"on_sale":false,"in_stock":true,"available_quantity":9}]}
