● Introduction
The ISSC BM57SPP05 Bluetooth module is design for Bluetooth standard SPP/ BLE electronic accessories via Bluetooth connectivity.
It is available in the 2.4GHz ISM band Class 2 Radio, compatible with Bluetooth Core Specification Version 3.0/ 4.0 + EDR.
ISSC IS1677NM single chip solution combines transceiver and baseband function to decrease the external components.
It narrows down the module size and minimizes its cost.
The optimized power design minimize power consumption to keep low battery.
