Very low power application module for Bluetooth® Smart v4.2


  • Bluetooth v4.2 compliant
  • High performance, ultra-low power Cortex-M0 32-bit core
  • Programmable embedded 160 KB Flash
  • AES security co-processor

The SPBTLE-1S is a Bluetooth® low Energy System-on-Chip application processor certified module, compliant with BT specifications v4.2 and BQE qualified. The module supports multiple roles simultaneously and can act at the same time as Bluetooth Smart master and slave device. It is based on BlueNRG-1 system-on-chip and entire Bluetooth Low Energy stack and protocols are embedded into the module. The SPBTLE-1S module provides a complete RF platform in a tiny form factor. Radio, embedded antenna and high frequency oscillators are integrated to offer a certified solution.
