{"title":"BLE Nano","handle":"ble-nano","url":"/products/ble-nano","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.\n\nThe 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.\n\nKey Features\n\n\nTiny Form Factor – Only 18.5 × 21.0 mm\n\nNordic nRF51822 SoC – ARM Cortex-M0 with Bluetooth 4.0 Low Energy\n\nBLE Central & Peripheral – Supports both roles for flexible connectivity\n\nUltra-Low Power – Ideal for battery-powered IoT projects\n\nFlexible Voltage – Operates from 1.8 V to 3.3 V (VDD) or 3.3–13 V (VIN)\n\nMultiple Dev Environments – Nordic SDK, mbed, GCC, Keil, or Arduino\n\nMK20 USB Board – Drag-and-drop firmware deployment via mass storage\n\n11 I/O Pins – With configurable UART, I2C, and SPI\n\n\nSpecifications\n\n\nMicrocontroller – Nordic nRF51822\n\nCMSIS-DAP Chip – Freescale MK20\n\nOperating Voltage – 1.8–3.3 V\n\nInput Voltage – 1.8–3.3 V (VDD) / 3.3–13 V (VIN)\n\nClock Speed – 16 MHz\n\nConnectivity – Bluetooth 4.0 LE, Serial (TX/RX), I2C, SPI\n\nFlash Memory – 256 KB\n\nSRAM – 16 KB\n\nI/O Pins – 11\n\nDimensions – 18.5 × 21.0 mm\n\n\nPower Supply\n\n\nVIN (3.3–13 V) – Regulated to 3.3 V via onboard LDO; connect a battery directly\n\nVDD (1.8–3.3 V) – Direct power input for low-voltage operation\n\n\n\nWarning: 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.\n\n\nPinout Notes\n\nOn-board LED is connected to Pin 19 (P0_19)\nPin 30 (P0_30) is a signal pin — configure via switches S5/S10 for GND or VDD\nUART pins (RTS, RXD, TXD, CTS) default to P8–P11 via switches S1–S4 and S6–S9\nUART can be rerouted to P0–P3 to free up analog pins\n\n\nMK20 USB Board\nThe 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.\n\nPackage Contents\n\n1× BLE Nano Board\n1× MK20 USB Board\n\n\nResources\n\nNordic nRF51822 SDK\n","vendor":"Little Bird","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":8775,"title":"Default Title","sku":"RB-BLENANO","price":17.57,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
