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

What’s more compact than a Feather but packs more power than a Trinket? The Adafruit ItsyBitsy ESP32 with a wFL external antenna connection. This compact powerhouse boasts the ESP32 Pico module with dual-core 240MHz Tensilica processor, making it perfect for performance-intensive projects.

The ItsyBitsy ESP32 offers WiFi and Bluetooth Classic + BLE connectivity, equipped with 8 MB of Flash memory and 2 MB of PSRAM for expanded capabilities. Despite its size, it features a USB to serial converter chip, power regulator, USB Micro B, buttons, NeoPixel, and Stemma QT I2C connector.

This is an ultra low power ESP32 board, with deep sleep consumption at just 10uA. Perfect for tight spaces, its integration includes crystal oscillator, flash, PSRAM, filter capacitors, and RF matching links in a singular package.

For those seeking range and gain, it replaces the usual PCB trace antenna with a w.FL connector, ideal for enclosures or when using larger dipole antennas. Keep in mind the unique MHF3 / IPEX3 / w.FL connection, and browse available WiFi antennas or adapters for seamless integration.

While the ItsyBitsy ESP32 doesn’t support native USB, it operates wirelessly via BLE and BT Classic. Compatible with Arduino IDE, CircuitPython, and MicroPython, it supports countless projects.

Specifications include:

• 240MHz Xtensa processor
• 8 MB Flash and 2 MB PSRAM
• 20 general-purpose IO pins, with analog and digital capabilities
• Built-in RGB NeoPixel LED and power control
• USB to Serial converter with high-speed UART
• Dual 8-bit analog output DACs
• SPI, UART, and I2S hardware support
• 8x Capacitive Touch support
• An output of 600mA and battery input pads with diode protection
• Reset switch for project re-initiation

Small yet mighty, each order includes a thoroughly tested ItsyBitsy ESP32 with headers for easy integration. Note that antennas are not included, but are available. Unleash this tiny titan’s potential in your next project!
