Usage
Description
1
Ultra-low
power
consumption
It supports WOR to reduce overall power consumption. In power-saving
mode(Mode 2), it can regulate overall power consumption by setting receiving
response delay; The maximum receiving response delay can be configured as
2000ms， and the average current is about 30uA.
2
Fixed
transmission
Module can communicate with other modules which work in different channels
and addresses, it is easy for networking and repeater.
For example: module A transmits AA BB CC to module B (address: 0x00 01,
channel: 0x80), HEX format is 00 01 80 AA BB CC (00 01 refers to the address of
module B, 80 refers to the channel of module B), then module B receives AA BB
CC (only module B).
3
Broadcast
transmission
Set the module address as 0xFFFF, then the module can communicate with other
modules in same channel.
4
FEC
Forward Error Correction, high coding efficiency & good correction
performance.
In the case of sudden interference, it can correct the interfered data packets
proactively, so that the reliability & transmission range are improved
correspondingly. Without FEC, those data packets can only be dropped.
5
Sleep mode
When the module works in sleep mode (mode 3), transmitting & receiving is not
available, while the configuration is available. The typical current is 5.0uA in this
mode.
6
Application
With better capability of penetration and diffraction than 2.4G, E30(915T20S) is
suitable for the open environment with few obstacles.

1. Introduction
1.1 Feature
E30(915T20S) is a 100mW wireless transceiver module(UART), half-duplex& transparent transmission, which
operates at 907~922.5MHz(default: 915MHz), TTL Level, compatible with the 3.3V and 5V IO port.
The module has the function of data encryption & compression. The data of the module transmitted over
the air features randomness. And with the rigorous encryption & decryption, data interception becomes
pointless. The function of data compression can decrease the transmission time & probability of being
interfered, while improving the reliability & transmission efficiency.
