Description
HT-M00 is a low-cost dual-channel gateway.It is located to smart family LoRa applications that work with less than 30PCS LoRa nodes. This gateway is based on two SX1276 chips driven by ESP32. We wrote a software mixer (also called a baseband simulation program) to make it possible to achieve 125KHz SF7~SF12 spreading factor monitoring.
Overview
- CE Certificate
- ESP32 + SX1276
- Size: 75 x 30 x 13mm
- Emulates LoRa demodulators
- Automatic adaptive spread spectrum factor, SF7 to SF12 for each channel is optional
- Maximum output: 18 ± 1dBm
- Communication interface Type-C USB
- The power supply voltage:5V
- Support for LoRaWAN Class A, Class C protocols
- Frequency range:
- Europe – 868MHz ISM band (863MHz to 870MHz range)
- Europe – 433MHz ISM band
- USA/Australia – 915MHz ISM band (902MHz to 928MHz range)
- China – 470MHz ISM band (470MHz to 510MHz range)
