1 Introduction
1.1 Brief Introduction
E22-230T30D is a new generation of LoRa wireless module, based on
the wireless serial port module (UART) of SEMTECH's SX1262 radio
frequency chip, with a variety of transmission methods, working in the
(220.125 ~ 236.125MHz) frequency band (default 230.125MHz), LoRa
spread spectrum technology , TTL level output, compatible with 3.3V and
5V voltage.
E22-230T30D adopts a new generation of LoRa spread spectrum technology. Compared with the traditional SX1276 solution, the
SX1262 solution has a longer transmission distance, faster speed, lower power consumption and smaller size; it supports air wake-up,
wireless configuration, carrier monitoring, automatic middle It supports functions such as follow-up and communication key, supports
sub-package length setting, and can provide customized development services.
1.2 Features
Based on SX1262, a new LoRa spread spectrum modulation technology is developed, which brings longer communication
distance and stronger anti-interference ability;
Support automatic relay networking, multi-level relay is suitable for ultra-long-distance communication, and multiple networks
run in the same area at the same time;
Support users to set the communication key by themselves, and it cannot be read, which greatly improves the confidentiality of
user data;
Support LBT function, monitor the channel environmental noise before sending, which can greatly improve the communication
success rate of the module in harsh environments;
Support RSSI signal strength indicator function for evaluating signal quality, improving communication network, and ranging;
Support wireless parameter configuration, send command data packets wirelessly, configure or read wireless module parameters
remotely;
Support air wake-up, that is, ultra-low power consumption, suitable for battery-powered applications;
Support fixed-point transmission, broadcast transmission, channel monitoring;
Support deep sleep, the power consumption of the whole machine in this mode is about 2uA;
Support 230MHz power frequency band, the penetration and diffraction ability is stronger than 433MHz;
The module has built-in PA+LNA, and the communication distance can reach 10km under ideal conditions;
The parameters are saved after power-off, and the module will work according to the set parameters after power-on again;
Efficient watchdog design, once an exception occurs, the module will restart automatically, and can continue to work according
to the previous parameter settings;
Support data transmission rate from 0.3k to 15.6kbps;
Support 3.3 ~ 5.5V power supply, more than 5V power supply can ensure the best performance;
Industrial-grade standard design, support long-term use at -40 ~ +85
