Adafruit ItsyBitsy ESP32 - wFL Antenna - 8 MB Flash / 2 MB PSRAM

The Adafruit ItsyBitsy ESP32 is a compact and versatile development board that's larger than a Trinket but smaller than a Feather, making it ideal for a variety of projects. At its core is the ESP32 Pico module, an FCC-certified chip featuring a dual-core 240MHz Tensilica processor, WiFi, Bluetooth Classic, and Bluetooth Low Energy (BLE). With 8MB of Flash memory and 2MB of PSRAM, this board is perfect for projects requiring both power and space efficiency.

The ItsyBitsy ESP32 includes useful accessories such as a USB-to-serial converter chip, power regulator, USB Micro B, buttons, NeoPixel, and a STEMMA QT I2C connector, making it well-suited for a range of tasks. It also offers ultra-low power consumption, with a deep sleep current of just 10uA.

This board stands out with its w.FL external antenna connection, allowing you to attach an external RF adapter or antenna for increased signal range, ideal for enclosures or when you need enhanced gain. The w.FL connector is not a common u.FL connector, so make sure to use compatible antennas or adapters.

Key Features:

• ESP32 PICO V3 chip with WiFi, Bluetooth Classic, and BLE
• 8MB Flash and 2MB PSRAM
• w.FL external antenna connection for boosted range and signal
• USB Micro B for easy programming and connectivity
• Built-in NeoPixel and Red LED
• STEMMA QT I2C connector for easy integration with I2C devices
• Ultra-low power consumption with light sleep at 4mA and deep sleep at ~10uA
• 20 I/O pins with various capabilities, including PWM, analog, I2C, SPI, UART, and more
• Capacitive touch on 8 pins with no extra components required
• Dual 8-bit DACs on analog pins A0/A1
• Battery input pads for external batteries (up to 6V) with diode protection
• Supports Arduino IDE, CircuitPython, and MicroPython
• Built-in USB-to-serial converter for debugging and uploading code

The ItsyBitsy ESP32 is a great choice for IoT projects, wireless communication, and low-power applications, all packed into a small form factor. It features built-in RGB NeoPixel for easy visual feedback and offers compatibility with a range of accessories for expanding its capabilities. Whether you're working with sensors, displays, or other peripherals, this board has the power and flexibility to meet your needs.

Please note that while the board includes headers for breadboard use, an antenna is not included but can be purchased separately from Adafruit’s shop.

With its small size, low power consumption, and flexible I/O options, the Adafruit ItsyBitsy ESP32 is perfect for developers looking for a compact, high-performance microcontroller for a wide range of applications.
