Chengdu Ebyte Electronic Technology Co., Ltd.
1.1 Introduction
E104-BT5040U is a small Bluetooth wireless module with USB interface
designed and produced by Ebyte; the function and pin of the module
correspond to the official Nordic nRF52840 USB Dongle module (the relevant
schematic diagram can be downloaded on the official website of Nordic). It
comes with a high-performance PCB antenna and uses the Bluetooth Low
Energy (BLE) SOC solution.
E104-BT5040U uses Nordic imported genuine nRF52840 RF chip which
supports Bluetooth 4.2 and Bluetooth 5.0; the chip comes with
high-performance ARM CORTEX-M4 core, 32M+32.768kHz industrial-grade
crystal oscillator, and has UART, I2C, SPI, ADC, DMA Rich peripheral resources such as, PWM, etc.; nRF52840 leads to most of the
I/O ports (please check the pin definitions for details), which is convenient for users to carry out multi-directional development.
E104-BT5040U is a hardware platform with factory program. See below for specific usage.
