Gigawit GWBMD0x Bluetooth 4.0 BLE module

The GWBMD0x is a Bluetooth 4.0 single-mode module based on the nRF51822 BLE protocol processor from Nordic Semiconductor. The nRF51822 is a powerful, flexible multiprotocol SoC suitable for Bluetooth Smart and 2.4 GHz ultralow-power wireless applications. It is built around a 32-bit ARM Cortex M0 CPU with 256 KB/128 KB Flash +32 KB/16 KB RAM.

GWBMD0x is an RF-designed module with almost full function as a Nordic nRF51822 chipset. Because of the programming flexibility in nRF51822, the 12 GPIOs in the module can be programmed as serial interfaces, PWM, analog, DIO, I2C, SPI, etc. This enables complete design flexibility associated with pin-out location and function. It is a suitable module for users wanting to use nRF51822 as their design solutions.

The product is FCC qualified with an embedded antenna. Performance is maximised with a 95 dB link budget compatible with Nordic SDK and its iBeacon reference design, providing an open and flexible development platform for developers to link their applications to iOS and Android devices.

The 15 x 15 mm module includes an integrated 16 MHz/32768 Hz crystal and DC/DC converter. Power consumption is 13 mA at peak, <0.5 µA at power down and <2.5 uA in idle mode. TX is -20 to 4 dBm, while RX is -92.5 dBm. Other features include GAP, GATT, L2CAP, SMP Bluetooth low energy profiles; rich and flexible peripheral IOs; and support for Master and Slave mode.
