It uses the ESP32 PICO ECO V3 in an FCC-certified ESP32 Pico module, combining a dual-core 240MHz processor with 2.4GHz Wi-Fi, Bluetooth® Classic and BLE, plus 8 MB of Flash and 2 MB of PSRAM.Adafruit has added the extras that make it easy to drop into real projects, including a USB to serial converter, USB Micro B connector, power regulator, buttons, a built-in RGB NeoPixel, a red status LED, and a STEMMA QT I2C connector. It is also designed for low-power work, with light sleep at 4mA and deep sleep at around 10uA.Because the ESP32 does not have native USB support, the USB connection is provided through the onboard USB to serial converter rather than direct USB device functionality. That means it cannot act as a USB keyboard or mouse, but it can still be used wirelessly over BLE or Bluetooth® Classic. It can be used with Arduino IDE, CircuitPython or MicroPython, and each board comes assembled and tested with headers you can solder on for breadboard use.Features:Form factor: Same size, form-factor as the remaining ItsyBitsy mainboards.Pinout: Similar but not identical pinout.Antenna area: There are no pins at the end of the board like most other ItsyBitsy's due to the radio antenna being there.USB connector: USB Micro B.Processor: ESP32 V2 03 Dual Core 240MHz Xtensa processor.Engineering revision: The ESP32 you know and love, with the latest engineering fixes.Ecosystem: Massive user base and thousands of existing projects and libraries to use.Wi-Fi: WiFi for IoT project usage.Bluetooth LE: Bluetooth® LE for IoT project usage.Bluetooth Classic: BT Classic for IoT project usage.Flash memory: 8 MB Flash.PSRAM: 2 MB PSRAM.USB to serial: USB to Serial converter built-in.UART: High-speed UART for debugging and uploading.Auto-reset: Auto-reset circuit works perfectly with any ESP32 uploading tool.Arduino support: Can be used with Arduino IDE.CircuitPython support: Can be used with CircuitPython.MicroPython support: Can be used with MicroPython.RGB LED: Built-in RGB NeoPixel LED.NeoPixel power control: Power control to reduce quiescent power in deep sleep.Status LED: Built-in Red LED on pin D13.5V logic output: 5V level-shifted output on D5.NeoPixel-friendly output: Perfect for driving NeoPixels or other devices that want 5V logic signal.Battery input: Battery input pads on the underside.Battery protection: Diode protection for external battery packs up to 6V input.GPIO count: 20 General Purpose "IO" pins.Pad breakout: 20 Pads expose pins from the ESP32.Analog input only pins: 3 are analog input only (A3, A4, A5).Digital output only pin: 1 is digital output only (5) with 5V level shifted up.Analog inputs: 13 x 12-bit analog inputs (A0, A1, A2, A3, A4, A5, D12, D13, D14, SDA, SCL, D32, D33).DAC outputs: Dual 8-bit analog output DACs on A0/A1.PWM: PWM outputs on any pin.I2C: I2C port with STEMMA QT plug-n-play connector.Additional I2C: A second I2C port can be defined on any other pins.Hardware UART: Hardware UART in addition to the USB-serial UART.Hardware SPI: Hardware SPI on the high speed SPI peripheral pins.Additional SPI: A second SPI port can be defined on any other pins.Hardware I2S: Hardware I2S on any pins.Capacitive touch: 8 x Capacitive Touch with no additional components required.Voltage regulator: 3.3V regulator with 600mA peak output.Light sleep current: Light sleep at 4mA.Deep sleep current: Deep sleep at ~10uA.Reset switch: Reset switch for starting your project code over.Bootloader access: Reset switch for entering bootloader mode.User switch: User switch on pin 35.Size: Really small.Included: Each order comes with one assembled and tested ItsyBitsy ESP32 with headers that can be soldered in for use with a breadboard.Specifications:Product Dimensions: 36.0mm x 17.6mm x 6.9mm / 1.4" x 0.7" x 0.3"Product Weight: 3.7g / 0.1ozA handy fit for compact IoT builds, wearable projects and battery-powered prototypes, especially if you want ESP32 wireless features in a small breadboard-friendly board with STEMMA QT support. **Product Type:** Wireless Microcontroller Board ## Images -
