It can be operated with the wireless protocols Bluetooth 5.0, Zigbee 3.0, Thread and Ant, as well as with proprietary 2.4GHz stacks.
The module comes in a 23.2×17.4x2mm package and contains the necessary components from radio to different antennas (PCB & ceramic) and the antenna-matching network or a U.FL/IPEX antenna plug for external antenna connection. Its metal cover ensures protection against unwanted radiation and electromagnetic waves.
Featuring an Arm Cortex-M4F processor with a core speed of 64MHz, the microcontroller offers sufficient computing power for “highly complex” algorithms and also for floating-point calculations, (due to the coprocessor) the manufacturer claims.
The 1MB flash memory can hold several radio stacks but also larger customer applications and it offers enough space for data logger tasks. Flexible power management is said to be achieved through the addition of an on-chip DC/DC converter and low-dropout (LDO) controller as well as automated power-saving mode.
The MS88SF2 is CE, FCC, IC, TELEC and BQB certified. The multi-protocol module enables network nodes in applications such as cycling computers, heart rate and blood pressure monitoring, blood glucose meters, scales, thermometers, mobile accessories, sports and fitness sensors, remote controls and toys, key fobs and wrist bands, 3D glasses and gaming controllers.
