Brief Introduction
FIG. 1 E73
E73 series are wireless Bluetooth modules designed by Chengdu Ebyte which feature small size, low power consumption, built in
PCB antenna . E73 series adopt the originally imported RFIC nRF52832of NORDIC, supporting BLE 5.0. The chip has
high-performance ARM CORTEX-M4F kernel and other peripheral resources, such as UART, I2C, SPI, ADC, DMA, PWM etc. The module led
out all the IO port of nRF52832 for multilateral development. For more details about nRF52832, please refer to the datasheet of NORDIC.
Compared with Bluetooth 4.2, Bluetooth 5 has the following advantages: Four data rates are now available 2Mbps, 1Mbps, 500kbps
and 125kbps. The 2Mbps clearly offers higher throughput possibilities. The broadcasting capacity is increased(x8). Broadcasting extension
makes the data length increase to 251 bytes which enables more effective data transmission in beacon applications.
E73 series are hardware platform without firmware, so users need to conduct a secondary development. This series have maximized
the RF characteristics of chip. The built-in 32.768K real-time clock crystal oscillator can benefit the users in programming.
