ITEM NAME:1pcs NRF51822 4.0 module/can be equipped with external antenna Specifications: nRF51822 uses 32-bit ARM Cortex M0 core, on-chip 256kB flash (when developing Bluetooth 4.0 programs, 176kb can be used for application development). Compared with 8/16-bit platform, it has better code density and faster execution speed. The Programmable Peripheral Interconnect (PPI) system provides a 16-channel bus that allows peripherals to communicate directly and autonomously without MCU intervention. This will reduce the delay caused by peripheral communication via the CPU, and keep the CPU dormant during the communication to reduce energy consumption. The chip has two power modes-ON/OFF, and all system modules and peripherals have independent power management to control the corresponding modules to switch between RUN/IDLE states according to task requirements. . The brand-new Radio module is the foundation of the excellent performance of nRF51822. The module supports Bluetooth low energy (Bluetooth low energy) and is compatible with Nordic's nRF24L series products. The output power range is between +4dBm to -20dBm, with a step of 4dB. Higher sensitivity can receive information ranging from -96 to -85dBm (depending on the data rate). The sensitivity in Bluetooth low energy mode is -92.5dBm. • Support multiple 2.4GHz radio • 32-bit ARM Cortex M0 processor • 256kB flash/16kB RAM • Software stacks available as downloads • The development method that the application program and the protocol stack are completely separated • 256kB Flash • Digital I/O • Fully compatible with nRF24L-series • Programmable output power from +4dBm to -20dBm • RSSI • 32kB RAM • Flexible and configurable 31 pin GPIO • Simple ON/OFF global power management • Full-featured digital interface: SPI/2-wire/UART • 10-bit ADC • 128-bit AES ECB/CCM/AAR co-processor • Ultra low-power 32kHz crystal and RC oscillators • Wide power supply voltage (1.8 V to 3.6 V) • On-chip DC/DC buck converter Package Including: mod.Find many great new & used options and get the best deals for 1pcs NRF51822 4.0 module/can be equipped with external antenna at the best online prices at Order2india Shopping!
