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.

Parameters Notes

When designing current supply circuit, 30% margin is recommended to be remained so as to ensure long-term stable operation of
the whole module.

The current at the instant of transmitting may be high, but the total energy consumed may be lower due to very short transmitting
time.

When using external antenna, the impedance matching degree at different frequency points between antenna and module may

The current consumed when the RF chip is only working at receiving mode is called as receiving current. The tested receiving
affect the transmitting current at different levels.
current may be higher for some RF chips with communication protocol or when the developers have loaded their own protocol to
the whole module.

The current at pure receiving mode is at mA level. To achieve µA level receiving current, the users need to manage it through
firmware development.

The receiving sensitivity is tested at the speed rate of 1kbps.

The turn-off current is always lower than the current consumed when the power supply source of the whole module is at no-load
status.

Each LRC component has ±0.1% error, and the error will accumulate since multiple LRC components are used in the whole RF
circuit, and the transmitting current will be different at different modules.

The power consumption can be lowered by lowering the transmitting power, but the efficiency of the internal PA will be decreased
by lowering transmitting power due to various reasons.

Notes
1. The module is embedded with ARM MCU. For program downloading, please use the J-LINK
downloader, any other serial port or JTAG、ISP、ICP are unavailable to download.
2. There are two ways to download the program. The protocol stack of NORDIC is not
programmed yet, so users need to use the official nRFgo studio of NORDIC to program the
protocol stack first, then program the hex of application code. Or, to program the protocol stack
of NORDIC first and download via the IAR or KEIL.

5. FAQ
5.1 Communication range is too short

The communication distance will be affected when obstacle exists.

Data lose rate will be affected by temperature, humidity and co-channel interference.

The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground.

Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.

The signal will be affected when the antenna is near metal object or put in a metal case.

Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the distance).

When the power supply at room temperature is lower than the recommended low voltage, the lower the voltage is, the lower the
transmitting power is.

Due to antenna quality or poor matching between antenna and module.
5.2 Module is easy to damage

Please check the power supply and ensure it is within the recommended range. Voltage higher than the peak will lead to a
permanent damage to the module.

Please check the stability of power supply and ensure the voltage not to fluctuate too much.

Please make sure anti-static measures are taken when installing and using, high frequency devices have electrostatic susceptibility.

Please ensure the humidity is within limited range for some parts are sensitive to humidity.

Please avoid using modules under too high or too low temperature.
