Micro SD TF Card Adapter Reader Module not working with Arduino UNO

[katcereno]

Hi,

I have recently purchased the MIcro SD TF card adapter reader module and connected the module to Arduino UNo with this manual Arduino - Micro SD Card | Arduino Tutorial (arduinogetstarted.com). However, after few attempts and uploading the code, it does not recognize the micro SD card I have inserted.

I appreciate all the help.

Post links to the exact hardware you're using, so to the Micro SD card adapter and the Micro SD card you're trying. Also post a sharp picture of your setup with all wires visible.

Hello,

• SD Card Adapter: AIHJCNELE 3pcs Micro SD TF Card Adapter Reader Module Memory Storage Breakout Board SDHC Card Read Write Module SPI Interface with Chip Level Conversion with Dupont Cable Line for Arduino Raspberry Pi : Amazon.ca: Electronics
• Arduino Board: Arduino UNO Wifi Rev2
• SD Card: Transcend UHS-I microSD 300s. 16 gb

Attached are the pinouts that I have for my setup.

Codes used:
Number 1: Arduino - Micro SD Card | Arduino Tutorial (arduinogetstarted.com)
Number 2: SD example -> CardInfo from ArduinoIDE (chipselect was 4. Also tried chpselect 10)

Trouble with Arduino Rev2 WIFI SPI

Hi, I'm having trouble using my Arduino Rev2 WIFI. I can't use the SPI communication and I tested my card, seems like the clock is dead but I did nothing that could break it. I ordered another card and had the exact same problem but my circuit works perfectly with an Arduino Rev 3 (without WIFI). I was wondering is there was a special set up for the Arduino Rev 2 WIFI Clock that I didn't do right. Did anyone had the same problem as me ? Any idea how to fix it ? Thanks for your help !

A quick read suggests that the UNO WiFi isn't quite compatible with an UNO when it comes to the SPI pins.

I see that SPI pins are different between the UNO and UNO Wifi Rev2. The link did not quite help with which pinouts should I transfer my SCK, MOSI and MISO. I'd appreciate if you have any ideas about it.

I was able to figure the pinouts out. Thank you all for all the help.

Arduino Board: Arduino UNO Wifi Rev2

The Arduino UNO WiFi isn't an Arduino UNO despite it's name. With the exception of the board layout and the voltage they have only the badly chosen name in common.

The only way to access the SPI pins is by the ICSP header.
