As compact and low-cost Bluetooth low energy (BLE) devices gain traction, Fujitsu introduced a new family of BLE modules based on Nordic Semiconductor’s nRF51822 SoC, built around a 32-bit ARM Cortex M0 CPU.
Ultra-compact, the two first family members, the MBH7BLZ01-
109003 and MBH7BLZ03-109004 modules come in two versions: 10.5 x 9.2 x 1.6 mm surface-mount module and a 15.7 x 9.8 x 2.0 mm surface-mount module with an antenna.
The power and cost-saving modules address consumer, medical, and emerging applications, such as 3D-motion sensors and environmental sensors. Both feature a built-in MCU to add upper-layer profiles easily, such as private profiles and application code. The modules include the complete verified and qualified BLE protocol stack. By separating the protocol stack and application code, an engineer can develop his or her application code assured that the code won’t corrupt the protocol stack.
Reference designs are available that include keyboard, mouse, and advanced navigation remotes. Samples and evaluation kits are available for purchase through Mouser and priced at $17.00 each, with mass production expected this month.
