Bluetooth® low energy Modules
LAPIS Technology's "MK71511 (A)" and "MK71521 (A)" are Bluetooth low energy single mode wireless modules for Bluetooth 5. "MK71511 (A)" has Nordic's nRF52811, and "MK71521 (A)" has Nordic's nRF52832. The "MK71511 (A)" and "MK71521 (A)" support 2 Mbps high-speed transmission, which is a feature of the Bluetooth 5 standard, and comunication data capacity increase (extended advertisement). It can handle data communication in time and up to 8 times more communication data. In addition, "MK71511 (A)" has a long-range transmission function, and since the communication distance is expanded to 4 times that of conventional Bluetooth, it is most suitable for indoor and outdoor applications. Furthermore, since it has a direction-finding function, it can also be applied to indoor location information services that can identify the location with high accuracy. On the other hand, "MK71521 (A)" has 512KB of large-capacity flash memory for storing programs, so it is most suitable for building a mesh network using Bluetooth and developing various applications. In addition, these two products can be easily replaced with the same shape and pin compatibility and can be mounted on an inexpensive 2-layer board, which also contributes to manufacturing cost reduction.
