Bluetooth low energy Module WT51822AA (256k) /AB (128k) (Bluetooth Low Energy BT4.0) PRODUCT SPECIFICATION Part number: BLE WT51822AA/AB Wavetek has developed a module which supports Bluetooth Low Energy (BLE) standards. Wavetek BLE module is a small sized, all purpose module which can be applied on peripherals devices and communicating with BLE equipped Mobile phone with low power consumption. In addition, this module is designed with SoC type BLE chip Nordic nrf51822 and can use a maximum of 25 GPIOs. Features The nrf51822 is a powerful, highly flexible multi protocol SoC ideally suited for Bluetooth low energy and 2.4GHz ultra low power wireless applications. The nrf51822 is built around a 32 bit ARM Cortex M0 CPU with 256kB flash + 16kB RAM. The embedded 2.4GHz transceiver supports Bluetooth low energy as well as 2.4GHz operation. nrf51822 also incorporates a rich selection of analog and digital peripherals that can interact without CPU intervention through the Programmable Peripheral Interface (PPI) system. A flexible 25 pin GPIO mapping scheme allows I/O like serial interfaces, PWM and quadrature demodulator to be mapped to any device pin as dictated by PCB requirements. This enables complete design flexibility associated with pin out location and function. nrf51822 supports the S110 Bluetooth low energy protocol stack as well as 2.4GHz protocol stacks, including Gazell, both available free of charge in the nrf518 Software Development Kit. nrf51822 requires a single power supply and gives the user the option of using on chip linear regulators giving a supply range of 1.8 3.6V, a direct 1.8V mode and a on chip DCDC buck converter giving a supply range of 2.1 3.6V. The use of the DC DC converter can be dynamically controlled during run time and enables nrf51822 to operate at radio peak currents below 10 ma @ 3V supply (TX @ 0 dbm & RX). Application Proximity tags, PUID watches, remote controls, sports/fitness/healthcare sensors.
