7)Compliance with Bluetooth Low Power Consumption(Bluetooth 4.0 )standard.

8)field strength RSSI

9)Maximum data rate 2Mbps

1064Bit Device ID. BLE Can be used for identification

11)Powerful and low-power 32 position ARM Cortex-M0 processor,Start-up time is 2μs,and 8/16 Bit Processor Comparisons,Greatly reduced activity time and increased code density.

12)Refinement of Power Supply Management,Individual system can switch independently,It can control clock autonomously based on activity level.

13)Programmable peripheral interconnection (PPI) system. Through Event Task Mechanism,Peripheral devices such as radio frequency transceivers、Timer and ADCI/OThe interaction between the processor and the other is completely free from the involvement of the processor.,Improving system efficiency greatly,More energy-saving.

14)EfficientEasyDMARadio Frequency Transceiver Interface is Flexible RAM mapping FIFO.

15)Highly flexibleGPIO mapping. Most of the figures IO Users can customize pin location. Simplification PCB Design,Help to reduce the number of layers of wiring.

16)custom 2 Internal Storage Protection Device (MPU) Low power consumption for user programs and precompiled protocol stacks such as Bluetooth and Gazell™Runtime protection。 nRF51 Series software architecture has a unique and powerful partition between protocol stack and user application,Provide maximum flexibility for application developers、Developing Simplicity and Code Security.

17)The stack is 100% Asynchronous and event-driven,And provide thread security management program calls to the application layer (SVC) Application Program Interface (API),User-friendly understanding and Application.

18)Simple programming model,No dedicated application framework or scheduler/RTOS Dependency,YesCLanguage foundations can be developed quickly.

19)Protocol stack and application code have no link time dependency,It can be compiled and updated independently./programming;Stack Runtime Protected,Ensure interoperability and reduce the risk of application errors affecting the stack.

20nRF51 series IC Code and pin compatibility,Allow a basic code,Reuse in different projects. The benefits of pin compatibility are not only in development、Re-use of hardware design for different projects in prototyping and production processes,It can also be easily transferred to another sibling. IC.

21)OriginalTASKwithEVENTconcept,Operating chip peripherals are very convenient and concise,You only need to configure a fairly small number of registers.,It's easy to use all kinds of peripherals.
