1.Overview
1.1 Introduction
The E104-BT54S module is a wireless SOC module designed based
on the BLUENRG355MC chip solution..It has a variety of transmission
methods, working in the 2.4GHz frequency band, TTL level output, and
3.3V IO port voltage.
The BLUENRG355MC chip is based on a high-performance ARM
Cortex-M0+ 32-bit core processor with a working frequency of 1MHz-64
MHz. The chip is embedded with high-speed memory (up to 64kbytes of
SRAM), as well as a wide range of enhanced I/Os and peripherals. For more information on the chip, please refer to the
official documentation.
This module is a pure hardware SoC module without a program at the factory. The Bluetooth-based function of
broadcasting, scanning, connection, transparent transmission etc. can only be used after users’ secondary development on
it..
