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

What's smaller than a Feather but larger than a Trinket? It's an Adafruit ItsyBitsy ESP32 with a wFL external Antenna Connection, a powerful processor PCB with a plethora of pins! It features the ESP32 Pico module, an FCC-certified module that contains an ESP32 chip with dual-core 240MHz Tensilica processor, WiFi, and Bluetooth® Classic + BLE, configured with 8 MB of Flash memory, and 2 MB of PSRAM.

This ultra low power ESP32 board includes a USB to serial converter chip, power regulator, USB Micro B connector, buttons, NeoPixel, and Stemma QT I2C connector to outfit this versatile chip for any task. It has a deep sleep current consumption of 10uA.

The ESP32 (PICO ECO V3) chip integrates all peripheral components, including crystal oscillator, flash, PSRAM, filter capacitors, and RF matching links in one package, making this board perfect for small space projects.

This version replaces the PCB trace antenna with a w.FL connector for attaching an external RF adapter or antenna, ideal for enclosures or boosting signal gain.

Note: The w.FL antenna connector is not a common u.FL connector. Compatible antennas and adapters are available separately.

This board does not have native USB support and cannot act as a USB keyboard or mouse, but supports BLE and Bluetooth Classic for wireless communication.

Features:

• Same size and form-factor as other ItsyBitsy boards (20 pins exposed, no pins at antenna end)
• USB Micro B connector for power and serial communication
• ESP32 V2 03 Dual Core 240 MHz Xtensa processor with WiFi, Bluetooth LE, and BT Classic
• 8 MB Flash and 2 MB PSRAM memory

• Compatible with Arduino IDE, CircuitPython, and MicroPython
• Built-in RGB NeoPixel LED with power control
• Built-in Red LED on pin D13
• 5V level shifted output on D5 for driving NeoPixels or other 5V logic devices
• Battery input pads for up to 6V battery input with diode protection
• 20 GPIO pads including 3 analog input only, 13 12-bit analog inputs, dual 8-bit DAC outputs, PWM outputs
• I2C port with STEMMA QT plug-n-play connector
• Additional hardware UART, SPI, I2S, and capacitive touch inputs
• 3.3V regulator with 600mA peak output
• Low power consumption: light sleep at 4mA, deep sleep at ~10uA
• Reset switch and user switch on pin 35
• Compact dimensions: 35.6mm x 17.8mm x 7.2mm

Each order includes one assembled and tested ItsyBitsy ESP32 with headers for breadboard use (soldering required). Antenna is sold separately.
