Emakefun BLE Nano for Arduino with Wireless BLE and Micro-USB Interface,TICC2540 Chip,Compatible to Arduino Nano V3.0

• Main chip for ATMEGA328P-MU QFN32 package, Burning the latest Bootloader (Arduino IDE 1.8.8), Download faster and more stable.Fully compatible with older versions.
• Combining common Nano board functions with CC2540 BLE functions, It is very convenient to be applied in various wireless connection application scenarios.
• The BLE chip is TI CC2540 BLE (SOC) chip.Maximum support 1Mbps air data transfer rate, stable performance.Communication distance can reach 30M in an open environment.
• PCB size is only 48mm*19mm.The pins are fully compatible with Nano V3.0. The main board has been welded and the pin row does not need to be welded by itself. Micro usb interface is adopted, which is more convenient to use.

<p>The  BLE Board has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega328P provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An  TI CC2540 chip on the board channels this serial communication over USB and the  TI CC2540 chip drivers (included with the Arduino software) provide a virtual com port to software on the computer. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the  TI CC2540 chip and USB connection to the computer (but not for serial communication on pins 0 and 1). A SoftwareSerial library allows for serial communication on any of the Nano's digital pins. The ATmega328P also support I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify use of the I2C bus. To use the SPI communication, please see ATmega328P datasheet. </p> <p>Microcontroller ATmega328P</p> <p>TI CC2540 BLE 2.4G wireless</p> <p>Architecture AVR</p> <p>Operating Voltage： 5 V</p> <p>Flash Memory 32 KB of which 2 KB used by bootloader</p> <p>SRAM ：2 KB</p> <p>Clock Speed ：16 MHz</p> <p>Analog I/O Pins ：8</p> <p>EEPROM： 1 KB</p> <p>DC Current per I/O Pins 40 mA (I/O Pins)</p> <p>Input Voltage： 7-12 V</p> <p>Digital I/O Pins： 22</p> <p>PWM Output： 6</p> <p>Power Consumption： 19 mA</p> <p>PCB Size ：48 x 19mm</p> <p>Weight ：7 g</p><b> Note: Please use Arduino IDE 1.8.6 or higher version.
