Adafruit ItsyBitsy ESP32 - wFL Antenna

Meet the Adafruit ItsyBitsy ESP32 - with a compact size like a Feather but more advanced like a Trinket! This PCB features the ESP32 Pico module with a powerful 240MHz dual-core Tensilica processor and FCC certification for top performance. With WiFi, Bluetooth classic, and BLE capabilities, this board is configured with 8 MB of Flash memory and 2 MB of PSRAM for optimal storage and processing power. Don't miss out on this versatile and powerful device.

This state-of-the-art ESP32 board includes a variety of useful additions, such as a USB to serial converter chip, power regulator, USB Micro B, buttons, NeoPixel, and Stemma QT I2C connector, making it well-equipped for a wide range of tasks. Additionally, with a deep sleep current consumption of only 10uA, this board is incredibly energy-efficient.

Featuring the ESP32 (PICO ECO V3) chip, the Itsy is powered by a single 2.4 GHz Wi-Fi and Bluetooth combo chip expertly designed with TSMC's 40 nm low-power technology. In fact, the ESP32 PICO integrates all necessary components - such as a crystal oscillator, flash, PSRAM, filter capacitors, and RF matching links - into one compact package, making it ideal for compact spaces like the ItsyBitsy.

This ItsyBitsy is exactly like our other ItsyBitsy ESP32 with 8 MB PSRAM, but instead of a PCB trace antenna, there's a w.FL connector for attaching an external RF adapter or antenna. Perfect for use in enclosures or when you want a boost in gain from a bigger dipole. 

Warning! The antenna connection is an MHF3 / IPEX3 / w.FL is not a common u.FL connector. Check out the WiFi Antenna with w.FL / MHF3 / IPEX3 Connector we carry or the RP-SMA to w.FL / MHF3 / IPEX3 Adapter if you already have an RP-SMA antenna.

Please note, like other ESP32 modules, the ItsyBitsy ESP32 does not have native USB support - instead, there's a USB to serial converter chip. This means it cannot act like a USB keyboard or mouse, but it does have BLE and BT classic so that you could use it wirelessly.

Here are some of the updates you can look forward to when using ItsyBitsy ESP32:

• Same size, form-factor as the remaining ItsyBitsy mainboards - with a similar but not identical pinout (there are no pins at the end of the board like most other Itsy's due to the radio antenna being there)
• USB Micro B - To maintain compatibility with the rest of the ItsyBitsy's
• ESP32 V2 03 Dual Core 240MHz Xtensa processor - the ESP32 you know and love, with the latest engineering fixes. Massive user base and thousands of existing projects and libraries to use.
• WiFi, Bluetooth LE, and BT Classic for any IoT project usage with ultra-low power consumption
• 8 MB Flash & 2 MB PSRAM
• USB to Serial converter built-in with high-speed UART for debugging and uploading, auto-reset circuit works perfectly with any ESP32 uploading tool.
• Can be used with Arduino IDE, CircuitPython or MicroPython
• Built-in RGB NeoPixel LED with power control to reduce quiescent power in deep sleep
• Built-in Red LED on pin D13
• 5V level-shifted output on D5, perfect for driving NeoPixels or other devices that want 5V logic signal
• Battery input pads on the underside with diode protection for external battery packs up to 6V input
• 20 General Purpose "IO" pins:
  • 20 Pads expose pins from the ESP32:
    3 are analog input only (A3, A4, A5)
    1 is digital output only (5) with 5V level shifted up
  • 13 x 12-bit analog inputs (A0, A1, A2, A3, A4, A5, D12, D13, D14, SDA, SCL, D32, D33)
  • Dual 8-bit analog output DACs on A0/A1
  • PWM outputs on any pin
  • I2C port with STEMMA QT plug-n-play connector - a second I2C port can be defined on any other pins.
  • Hardware UART in addition to the USB-serial UART
  • Hardware SPI on the high speed SPI peripheral pins - a second SPI port can be defined on any other pins.
  • Hardware I2S on any pins
  • 8 x Capacitive Touch with no additional components required
• 3.3V regulator with 600mA peak output
• Light sleep at 4mA, deep sleep at ~10uA
• Reset switch for starting your project code over, for entering bootloader mode or for user reading
• User switch on pin 35
• Really small!

Each order comes with one assembled and tested ItsyBitsy ESP32 with headers that can be soldered in for use with a breadboard. Don't forget we do not include an antenna - but we do stock them in the shop.
