Supports license free ISM 433MHz band

It adopts LoRa spread spectrum technology, which features with strong anti-interference performance and long distance.

It allows users to set their own communication keys, which cannot be read, greatly improving the confidentiality of user data.

Features a power amplifier(PA), the maximum transmit power is 1W (30 dBm).

Using RF Filters effectively suppress higher harmonics.

The SAW + LNA + SAW cascade configuration is used to suppress interference and improve receiver sensitivity .

Using a temperature-compensated crystal oscillator (TCXO ) effectively improves frequency stability.

ESD protection measures have been added to the communication port, power port, and antenna port to effectively improve anti-static capability .

Power supply reverse connection protection is adopted.

Ultra-low operating voltage, can output full power even at as low as 3V.

The LDO with ultra-high PSRR effectively suppresses input power supply noise.

Onboard heatsinks reduce junction temperature, extend lifespan, and improve stability.

Supports AT command configuration

Supports Modbus programmable register read/write operations, allowing for flexible customization of product functions.

It supports over-the-air wake-up, i.e., ultra-low power consumption, and is suitable for battery-powered applications.

Supports transparent transmission and fixed-point transmission. Broadcast transmission, Channel monitoring, wireless relay and other functions
