## Description

The BLE Nano is the smallest Bluetooth 4.0 Low Energy development board available, measuring just 18.5 × 21.0 mm. Built around the Nordic nRF51822 SoC (ARM Cortex-M0 + BLE), it runs at 16 MHz with ultra-low power consumption and supports both BLE Central and Peripheral roles. The included MK20 USB Board (Freescale MK20DX128VFM5) acts as a programming dongle — it appears on your computer as both a serial port and a removable mass storage disk for easy firmware deployment. Development is supported via the Nordic nRF51822 SDK, mbed platform, GCC, Keil, or Arduino. Key Features Tiny Form Factor – Only 18.5 × 21.0 mm Nordic nRF51822 SoC – ARM Cortex-M0 with Bluetooth 4.0 Low Energy BLE Central & Peripheral – Supports both roles for flexible connectivity Ultra-Low Power – Ideal for battery-powered IoT projects Flexible Voltage – Operates from 1.8 V to 3.3 V (VDD) or 3.3–13 V (VIN) Multiple Dev Environments – Nordic SDK, mbed, GCC, Keil, or Arduino MK20 USB Board – Drag-and-drop firmware deployment via mass storage 11 I/O Pins – With configurable UART, I2C, and SPI Specifications Microcontroller – Nordic nRF51822 CMSIS-DAP Chip – Freescale MK20 Operating Voltage – 1.8–3.3 V Input Voltage – 1.8–3.3 V (VDD) / 3.3–13 V (VIN) Clock Speed – 16 MHz Connectivity – Bluetooth 4.0 LE, Serial (TX/RX), I2C, SPI Flash Memory – 256 KB SRAM – 16 KB I/O Pins – 11 Dimensions – 18.5 × 21.0 mm Power Supply VIN (3.3–13 V) – Regulated to 3.3 V via onboard LDO; connect a battery directly VDD (1.8–3.3 V) – Direct power input for low-voltage operation Warning: Do NOT supply power from both VIN and VDD simultaneously. Do NOT exceed 3.3 V on VDD or 13 V on VIN — exceeding these limits will damage the board. Pinout Notes On-board LED is connected to Pin 19 (P0_19) Pin 30 (P0_30) is a signal pin — configure via switches S5/S10 for GND or VDD UART pins (RTS, RXD, TXD, CTS) default to P8–P11 via switches S1–S4 and S6–S9 UART can be rerouted to P0–P3 to free up analog pins MK20 USB Board The MK20 USB Board powers the BLE Nano from USB (5 V regulated to 3.3 V) and provides drag-and-drop firmware deployment. Short switch S on the MK20 board to output 1.8 V instead, enabling low-voltage component operation. Package Contents 1× BLE Nano Board 1× MK20 USB Board Resources Nordic nRF51822 SDK
