LoRa ESP32 DEV KIT v1 shield for EByte E32 E22 RF 8km-12km range
LoRa or Long Range wireless data telemetry is a technology pioneered by Semtech that operates at a lower frequency than NRF24L01 (433 MHz, 868 MHz or 916 MHz agains 2.4 GHz for the NRF24L01) but at thrice the distance (from 3000m to 8000m).
You can find E32 here AliExpress (433MHz 3Km) - AliExpress (433MHz 8Km) - AliExpress (868MHz 3Km) - AliExpress (868MHz 8Km) - AliExpress (915MHz 3Km) - AliExpress (915MHz 8Km)
You can find here AliExpress (433MHz 4Km) - AliExpress (433MHz 10Km)
You can find the adapter for SMD modules on
We are going to test E32-TTL-100 and E22.
E32
It is a wireless transceiver module, operates at 410 441 MHz based on original RFIC SX1278 from SEMTECH, transparent transmission is available, TTL level. The module adopts LORA spread spectrum technology.
The module features FEC Forward Error Correction algorithm, which ensure its high coding efficiency & good correction performance. In the case of sudden interference, it can correct the interfered data packets automatically, so that the reliability and transmission range are improved correspondingly. But without FEC, those da te packets can only be dropped.
And with the rigorous encryption & decryption, data interception becomes pointless. The function of data compression can decrease the transmission time & probability of being interference, while improving the reliability & transmission efficiency.
E22
It is a wireless transceiver module, operates at 410 493 MHz based on original RFIC SX1268 from SEMTECH, transparent transmission is available, TTL level. The module adopts LORA spread spectrum technology.
Like the little brother e22 the module features FEC Forward Error Correction algorithm, which ensure its high coding efficiency & good correction performance. In the case of sudden interference, it can correct the interfered data packets automatically, so that the reliability and transmission range are improved correspondingly. But without FEC, those da te packets can only be dropped.
And with the rigorous encryption & decryption, data interception becomes pointless. The function of data compression can decrease the transmission time & probability of being interference, while improving the reliability & transmission efficiency.
Ebyte LoRa E22 device for Arduino, esp32 or esp8266 carrier sense
But more than e22 this module have a carrier sense features, that wait transmission if there are some air interference, can be used like a repeater, have watchdog that if there is an error device restart and continue working, have deep sleep for better power saving, and first the sx1268 with less power grant more power.
Ebyte LoRa E22 device repeater relay function ultra long distance
Remotely configure or read wireless module parameters by sending command packets wirelessly.
And finally have an important features the RSSI, you can check the signal strenght on all message sended.
