The RT38B01 is a UHF DTU (Data Terminal Unit) RS485 BUS RF Serial Port UART Transceiver Module, Operating in the 433-458MHz Frequency Range.
RS485 BUS RF Serial Port UART Transceiver Module
Overview
Module features
Long-distance wireless transmission (up to 500 meters in open area , 10kbps baud rate in the air )
Operating frequency range ( 433 - 458.5MHz , up to 255 communication channels)
Maximum 100mW ( 20dBm ) transmit power ( 10 levels of power can be set )
Built-in MCU, use serial port to communicate with external devices
Send 31 bytes at a time
The module can support one-to-one, one-to-many transparent transmission communication through ID setting Changing the baud rate of a different serial port will synchronously change the rate at which data is sent over the air. ( 10kbps-100kbps)
Set the ''critical three minutes''. The module can send and receive data normally within three minutes of power-on. You can send the AT command '' AT+ENABLE=1 '' to make the module enter the AT command state for parameter setting. There is only this reserved word in these three minutes. After more than three minutes, you will not be able to enter the AT command mode, you can only send and receive data, '' AT+ENABLE=1'' will also be sent out as data, there are no reserved words at this time.

How to use (>=2pcs):
- 1 2PCS,Module 1 and Module 2 send data to each other.
- 2 >=3PCS,One as master device, the other as will be as slave device.
the way they work as well as wired RS485 bus. Master device transmit data, Slave devices all receive data.Any slave device transmit data, master device and the other slave devices can receive .When ever only allowed one device (master or slave) to transmit data.

Completely Changed the Way I See Money!
Format: Paperback, Format: Paperback
This book is far more than just a read about finances; it’s a masterclass in financial education that can truly change your life. From the very first page, Robert Kiyosaki challenges you to think differently: stop working just for money and learn how to make money work for you.
I loved how he contrasts the lessons from his “Rich Dad” and “Poor Dad,” and how each story leaves you with practical lessons you can apply immediately. The 25th Anniversary Edition includes updated examples that make complex concepts easy to understand and incredibly actionable.
If you want to take control of your financial future, build income-generating assets, and break free from the “work for money” mindset, this book is an absolute must-read. It’s not just a book—it’s an investment in yourself!
⭐⭐⭐⭐⭐ Highly recommended for anyone who wants to improve their relationship with money and build wealth smartly.
