How to connect nRF2740 to Arduino Micro

[Alessandro Menegatti]

Hi, I'd like to connect my nRF2740 to my MCU Arduino Micro and test it with the sample codes found in your GIT repo. How can I do this? Best regards, Alessandro

Hi,

Please take a look at the readme file for the Arduino SDK. You should open one of the projects to see which pins are configured by default. I suggest starting with the hello world project.

The HW layout of the nRF8001 module can be found here.

Notice the following in the main readme file: “When using the nRF2740/nRF2741 modules directly wired to the Arduino:

When the Arduino uses a 5v microcontroller, you may have to use level converters or a resistive divider to get the voltage to 3.3v for the lines that are output from Arduino to the nRF8001. The Arduino(3.3v-1.9v) or the Arduino DUE can be wired directly to the nRF8001 without any level converters or resistive dividers.”

Best regards, Runar
