It's an \u003cstrong\u003eAdafruit ItsyBitsy nRF52840 Express \u003c\/strong\u003e featuring the \u003cstrong\u003eNordic nRF52840 Bluetooth LE \u003c\/strong\u003eprocessor! Teensy \u0026amp; powerful, with an fast nRF52840 Cortex M4 processor running at 64 MHz and 1 MB of FLASH - this microcontroller board is perfect when you want something very compact, with a heap-load of memory and Bluetooth LE support This Itsy is your best option for tiny wireless connectivity - it can act as both a BLE central and peripheral, with support in both Arduino and CircuitPython\u003c\/p\u003e\u003cp\u003eItsyBitsy nRF52840 Express is only 1.4\" long by 0.7\" wide, but has 6 power pins, 21 digital GPIO pins (6 of which can be analog in). It's the same chip as the Feather nRF52840 but \u003cem\u003ereally really small\u003c\/em\u003e. So it's great for thse really compact builds. It even comes with 2MB of QSPI Flash built in, for data logging, file storage, or CircuitPython code.\u003c\/p\u003e\u003cp\u003eThe most exciting part of the ItsyBitsy is that while we ship it with an Arduino IDE compatible demo, you can also install CircuitPython on board with only a few clicks. When you plug it in, it will show up as a very small disk drive with code.py on it. Edit code.py with your favorite text editor to build your wireless-enabled project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can't install software on. When you're done, unplug the Itsy' and your code will go with you.\u003c\/p\u003e\u003cp\u003eHere are some of the updates you can look forward to when using ItsyBitsy nRF52:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\nSame size, form-factor as the remaining ItsyBitsy mainboards - with a similar but not identical pinout (there's no pins at the end of the board like most other Itsy's due to the radio antenna being there.\u003cstrong\u003e \u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eFloating point support with Cortex M4 DSP instructions \u003c\/li\u003e\n\u003cli\u003e32-bit, 3.3V logic and power with power\/enable pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1024 KB\u003c\/strong\u003e flash, \u003cstrong\u003e256 KB\u003c\/strong\u003e RAM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 MB QSPI FLASH chip\u003c\/strong\u003e for storing files and CircuitPython code storage.\u003c\/li\u003e\n\u003cli\u003eNative Open Source USB stack - pre-programmed with UF2 bootloader\u003c\/li\u003e\n\u003cli\u003eBluetooth Low Energy compatible 2.4GHz radio (Details available in the nRF52840 product specification)\u003c\/li\u003e\n\u003cli\u003eFCC \/ IC \/ TELEC certified module\u003c\/li\u003e\n\u003cli\u003eUp to +8dBm output power\u003c\/li\u003e\n\u003cli\u003e21 GPIO, 6 x 12-bit ADC pins, up to 12 PWM outputs (3 PWM modules with 4 outputs each)\u003c\/li\u003e\n\u003cli\u003eRed LED for general purpose blinking, mini DotStar RGB LED for colorful feedback\u003c\/li\u003e\n\u003cli\u003e1 x Special \u003cstrong\u003eVhigh\u003c\/strong\u003e output pin gives you the higher voltage from VBAT or VUSB, for driving NeoPixels, servos, and other 5V-logic devices. \u003cstrong\u003eDigital 5\u003c\/strong\u003e level-shifted output for high-voltage logic level output.\u003c\/li\u003e\n\u003cli\u003eNative USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, Keyboard\/Mouse HID, even a little disk drive for storing Python scripts.\u003c\/li\u003e\n\u003cli\u003eCan be used with Arduino IDE or CircuitPython\u003c\/li\u003e\n\u003cli\u003eComes pre-loaded with the UF2 bootloader, which looks like a USB storage key.
