E80-400M2213S LR1121 chip Industrial power LoRa dual-band wireless RF transceiver module Sub-G Internet of Things 433/868/915/2.4G patch
[Working frequency]：410-493M/2.4GHz
[Transmitting power]： 21.5/13dBm
[Communication distance]： 5.6/2.6km
[Product size]：26*16mm
[Introduction]：E80-400M2213S is a dual-band SMD LoRa hardware SPI wireless module independently developed based on SEMTECH's LoRa Connect™ LR1121 chip for multi-band global connectivity, with transmit powers of 22dBm and 13dBm respectively. An industrial-grade 48MHz high-precision low-temperature drift crystal oscillator is integrated inside the module. LR1121 is SEMTECH's third-generation ultra-low power LoRa transceiver. It provides multi-band LoRa and long-range frequency hopping spread spectrum (LR-FHSS) communications based on Sub-GHz and 2.4 GHz ISM bands, as well as satellite s-band connectivity. At the same time, it remains configurable to meet different application requirements and proprietary protocols.
| RF parameters | Parameter value | Remark |
| Working frequency band (MHz) | 410-493 | @Sub-GHz, users can program the module to work at different frequencies |
| 2400-2500 | @2.4GHz, users can program the module to work at different frequencies | |

| Maximum transmit power (dBm) | 21.5 | @Sub-GHz, user can adjust the output power through programming |
| 13 | @2.4GHz, user can adjust the output power through programming | |
| Receiving sensitivity (dBm) | -136 | @Sub-GHz，BWL=125kHz, SF=9 |
| -129 | @2.4GHz，BWL=406kHz, SF=7 | |
| Reference communication distance (km) | ≤5.6 | @Sub-GHz, clear and open environment, antenna gain 3.5dBi, antenna height 2.5 meters, air rate 2.4kbps |
| ≤2.6 | @2.4GHz, clear and open environment, antenna gain 5dBi, antenna height 2.5 meters, air rate 2.4kbps |
| Electrical parameters | minimum value | Typical value | maximum value | Remark |
| Working voltage (V) | 1.8 | 3.3 | 3.7 | ≥3.3V can guarantee the output power. If it exceeds 3.8V, there is a risk of burning. |
| Communication level (V) | - | 3.3 | - | There is a risk of burning when using 5V TTL. Users should use the conversion circuit rationally. |
