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.
