How to connect DFR0229 SD card module to Arduino Nano BLE 33 sense?

Hello,

How to connect DFR0229 SD card module to Arduino Nano BLE 33 sense?

I found this page SPI on Arduino Nano 33 BLE Sense
However I don't understand where is D13, maybe I am missing something obvious?

Thanks,

Alice

From the page that you linked to

This module has SPI interface and 5V power supply

So you will need to supply it with 5V and put voltage converters on the SPI lines to avoid a mismatch of voltages and possible damage to the the Arduino board

Pin 13 is top/left (D13) in this diagram in the same place as a standard Nano

Thanks for the answer, I was indeed missing something obvious and didn't see that D13 was on the top left.

However I haven't manage to make the program work. I only get :

12:20:29.085 -> Initializing SD card...initialization failed. Things to check:
12:20:29.085 -> * is a card is inserted?
12:20:29.085 -> * Is your wiring correct?
12:20:29.085 -> * did you change the chipSelect pin to match your shield or module?

So I have
MISO = D12
SCK = D13
SS = D10
MOSI = D11
GND = GND
5V = 5V

I tried to connect SS to D4, but same result. I also tried to Connect 5V to Vin and the red led on the SD module light on whereas it was off when on V5. I am starting to worry that this module can work on Arduino Nano.

I thought this SD module could be incompatible with Arduino nano (because the need of 5V), so I tried on an Arduino Uno but it isn't working neither. (the code compile but nothing even appear in the serial monitor)
Does anyone would have an idea on the reason?

Thanks

Please post your sketch, using code tags when you do

Yes sorry, I was using the Cardinfo example from SD library

/*
  SD card test

  This example shows how use the utility libraries on which the'
  SD library is based in order to get info about your SD card.
  Very useful for testing a card when you're not sure whether its working or not.

  The circuit:
    SD card attached to SPI bus as follows:
 ** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
 ** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
 ** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
 ** CS - depends on your SD card shield or module.
 		Pin 4 used here for consistency with other Arduino examples

but in the sketch

const int chipSelect = 4;

yes I was either using connecting SS to D4 with the previous code, or trying to replace the line you have quoted by with SS =D4

const int chipSelect = 10;

Hello,
I made some more tests. Now I am only using only SS=D4 with the initial example program.

I wanted to know if there was this problem because the SD module is said to work at 5V. I also found another SD module (but I don't know its reference).

  1. I tried the program with an Arduino Uno with both SD module but nothing occurs on the serial monitor even the Initializing SD card... message

  2. Arduino nano + DFrobot SD module : I get the message:
    10:27:21.295 -> 10:27:21.295 -> Initializing SD card...initialization failed. Things to check: 10:27:23.378 -> * is a card inserted? 10:27:23.378 -> * is your wiring correct? 10:27:23.378 -> * did you change the chipSelect pin to match your shield or module?
    I tried to connect the 5V pin of the module on :

  • Vin -> the red led light on
  • 5V -> no light
  • 3.3V -> red light on
  • 5V / GND of the Arduino Uno
    but same result in the serial monitor for the 4 tries.
  1. Arduino Nano with the unknown reference SD module
    I get a normal result
10:48:06.959 -> 
10:48:06.959 -> Initializing SD card...Wiring is correct and a card is present.
10:48:06.959 -> 
10:48:06.959 -> Card type:         SDHC
10:48:06.959 -> Clusters:          950688
10:48:06.959 -> Blocks x Cluster:  64
10:48:06.959 -> Total Blocks:      60844032
10:48:06.959 -> 
10:48:06.959 -> Volume type is:    FAT32
10:48:06.959 -> Volume size (Kb):  30422016
10:48:06.959 -> Volume size (Mb):  29709
10:48:06.959 -> Volume size (Gb):  29.01
10:48:06.959 -> 
10:48:06.959 -> Files found on the card (name, date and size in bytes): 
10:48:07.006 -> SYSTEM~1/     2021-12-09 11:04:24
10:48:07.052 ->   WPSETT~1.DAT  2021-12-09 11:04:24 12
10:48:07.052 ->   INDEXE~1      2021-12-09 11:04:24 76

So I guess my Arduino Uno 's SPI connection is not working
Also I have 2 DFR0229 modules and I have tried both.
Does anyone have a clue what I do wrong? Is it possible that Arduino nano and DFR0229 are incompatible?

Thanks
