simpleRTK2Blite RaspberryPi direct connection

Q&A forumCategory: QuestionssimpleRTK2Blite RaspberryPi direct connection
Good morning,
We have successfully connected a unit of simplertk2b v1 to the UART port of a raspberry pi4. We would like to do the same with the lite, using the included xbee/usb adapter.
Is there any way of using the RX/TX/GND/5V connections in the adapter board included with the lite to connect it to raspberry pi?
Will the 5V power affect the 3v3 required by the pi for the uart? This adapter board has not IOREF pin “exposed”.
We have successfully connected the lite to the pi using the pins directly (3v3, GND, TX,RX), so we would like to use the adapter just a socket.
Thank you very much in advance

Hi Angel,
It should also be possible to use Lite. Lite supports both 3.3V input and 5V input, depending on the pin that you connect.
Secondly it has always 3.3V TX/RX pins, it doesn’t have IOREF.
This and more info is available here:

Thank you very much for your prompt answer.
As you stated, we have been able to connect the lite “directly”, without using the included adapter. However, our question related to using the adapter. Can we connect to the lite by connecting the raspberry pi to the GND-5V-TX-RX of the included adapter?
Again, thank you very much

Hi Angel,
Sorry for the delay.
Yes you can connect to the raspberry Pi via GND, TX, RX. About 5V i’m not sure what is your intention, it’s a 5V input in out board. It’s not a 5V output.

Thank you very much! It made sense, but didn’t want to fry anything…
