## Description

The Adafruit ItsyBitsy nRF52840 Express brings Bluetooth Low Energy connectivity to the tiny ItsyBitsy form factor. Powered by the Nordic nRF52840 Cortex M4 at 64 MHz with 1 MB Flash, 256 KB RAM, and 2 MB QSPI Flash, it can act as both a BLE central and peripheral device — perfect for compact wireless projects. At just 1.4" × 0.7", it supports both CircuitPython and Arduino IDE programming. The UF2 bootloader makes flashing as simple as dragging a file to a USB drive, and the FCC/IC/TELEC certified radio module provides reliable BLE connectivity with up to +8 dBm output power.
