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,

Unfortunately I don’t have a micro here right now, but I will check if I can order one. As far as I can see the Micro is a 5V board, so you should use resistive dividers or level converters for the lines. If you don’t, you risk damaging the nRF8001. However I have successfully connected the nRF8001 to the Arduino Uno without using dividers/convertes, but it is not possible to predict for how long it will take before the nRF8001 is damaged (It could be damaged right away).

About connecting the module to the micro; Did you try: Board_name = board default. REQN-> SS RDYN -> 3 MOSI -> MOSI MISO -> MISO SCK -> SCK RESET -> 4 VSS -> 3v3 GND -> GND

Notice that there is an example project called ble_aci_transport_layer_verification that can be used to verify if the transport layer is actually working on your board. Once you have verified that, you could try the hello world project.

Best regards, Runar

I'm actually using dividers and converters on each line. Please let me know when you will test it on a Micro board.
