NRF51822 2.4G Wireless Module Wireless Communication Module Bluetooth module

product description The Nordic Semiconductor nRF51822 is a multi-protocol Bluetooth low energy / 2.4 GHz dedicated RF single-chip solution for PC peripherals, Internet TV, toys, remote controls, sports / fitness / health sensors and automation applications. IC features include: 16 KB and 256 KB on-chip flash memory; Digital and mixed-signal surround, including SPI, 2-wire, ADC and quadrature decoder; 16 PPI channels On-chip load matching "When the supply voltage range of 1.8-3.6 V, 1.75 1.95 V" bypass mode; Slices and pulls out a 3V battery (such as a coin cell) out of the DC / DC converter; A 32 KHZ RC oscillator +/- 250 parts per million (PPM) for low power Bluetooth applications eliminates the need for external 32 KHZ crystals for cost savings and PCB space savings; 6x6mm 48pin QFN package, providing up to 32 GPIOs; A complete Bluetooth protocol stack (link layer to the configuration file). The NRF51822 S110 is a downloadable, royalty-free, precompiled binary Bluetooth stack that can be independently programmed and updated for low power consumption. Features include: Asynchronous API and event-driven SVC; Runtime protection GATT, GAP and L2CAP level APIs; Peripherals and radio roles; GATT client and server; Parallel protocol 2.4 GHz and above for RF proprietary protocols; Less than 128 KB of code and 6 KB of RAM, more than 128 KB of flash for applications and 10 KB of RAM; The nRF51822 stack running S110 reduces power consumption by as much as 50% compared to using the nRF8001 dual-chip generation. The S110 stack is used with the nRF51822 nRF518 SDK Product Details Product Size: 0.2 x 0.2 x 0.3 inch; 0.16 oz
