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..
1.2 Features
Support BLE 5.1;
A new Bluetooth module developed based on BLUENRG355MC;
Maximum transmit power 8dBm;
Support deep sleep, the power consumption of the whole machine in this mode is about 1.3uA;
Support the global license-free ISM 2.4GHz frequency band;
Flash: 256 kB; RAM: 64 kB;
3.3V～3.6V power supply, 3.3V power supply can guarantee the best performance;
Industrial grade standard design, can work under -40 ~ 85 °C for a long time;
IPEX interface/PCB antenna are available. .

5. Antenna Type
5.1 Antenna recommendation
The antenna plays an important role in the communication process. The inferior antenna often has a great impact on the
communication system. Therefore, we recommend some antennas that support our wireless modules and have excellent
performance and reasonable price.
