Description
The CMM-9304-V2.1 module is a miniaturised Bluetooth® Low Energy module based on EM
Microelectronic's low power fully integrated Bluetooth® low energy single-chip EM9304. Built in with a
highly efficient PCB antenna, this small sized, low cost module boasts one of the best power
consumption characteristics combined with outstanding Bluetooth Low Energy performances.
The flexible architecture of the EM9304 allows it to act as a companion IC to any ASIC or MCU-based
product, or as a complete System-on-Chip (SoC).
The module offers various possibilities of control via a simple SPI/UART interface: Host Controller
Interface (HCI) with the internal Bluetooth® v5.0 link layer; proprietary Application Controller Interface
(ACI) with the in-built Bluetooth® v4.2 stack, several profiles, and over-the-air firmware (FOTA)
updating routines.
