[Introduction]：E104-BT55SP is a small-sized, low-power Bluetooth module based on Bluetooth protocol version 5.3, working in the 2.4GHz frequency band. The E104-BT55SP module is developed by Ebyte based on the CC2340R5 chip of Texas Instruments (TI). The Bluetooth module has a 48-MHz Arm® Cortex®-M0+ processor, an integrated balanced-unbalanced transformer, and UART, I2C, SPI, ADC , DMA, PWM and other rich peripheral resources, and at the same time lead out all IO ports, which is convenient for users to carry out multi-directional development. The maximum supported baud rate is 3Mbps.
