Arduino Uno R3 to EM4095 & CC1101

Projects General Guidance

Hello everyone!

This is my first post here :laughing:

I just have a few questions, I'm hoping I could get some help with, I'm new to electronics so please excuse any dumb questions hahaha... My questions are as follows:

  1. I need to connect an Arduino Uno R3 to a EM4095 module for read and write. The EM4095 module has 6 connector pins, namely: 5V, GND, MOD, DEMOND-OUT, SHD, RDY. Its pretty logical connecting the GND and 5V. Does anyone know where to connect the remaining 4 pins? (I will provide the pinout diagrams)

  2. I would also like to connect two CC1101 modules to the same Arduino as the EM4095. Do I need a 5v to 3.3v logic level for this?

  3. If I do need a logic level, that would mean I have to connect the 5V and 3.3V pins of the arduino to the Logic level. Will this interrupt the functionality of the EM4095 since it also needs the 5V pin?

Your help would be greatly appreciated.

  1. and 2) Posting a link to the datasheets would help us a lot.
    3). No.

Thanks for your quick response bro. Here are the datasheets

It's a 5 volt device and can be directly connected to the UNO as I can see. It uses SPI.
Tsearching for " UNO + EM4095". Lots of projects have been done and tgere will be examples to find showing wiring, libraries etc. Take a look into the IDE examples for code to start from.
What's the CC1101?

Thanks, I'll do more research. I tried checking for examples but every example is different. lol... :broken_heart: Im only concerned about the wiring of 4 pins: Mod, Demod-out, SHD, RDY
The CC1101 is a transceiver module.

Check what pins the library use.
