📚 HiLetgo 5pcs Micro SD TF Card Adapter Reader Module with 6Pin SPI Interface for Arduino UNO R3 MEGA 2560 Due Review

See title. The other two devices worked great. All five were tested in the same socket on my DIY Teensy Dev. Board with the same software. If they all worked it would be great value for money. just so you know I've bought many, many things from HiLetgo in the past and everything has been perfect. That was the first problem. It has to happen sometime I think.

Do not buy for Teensy 3.2. Got this to help me upload sound files to the prop board for my Teensy 3.2. The Teensy boards have 3.3V logic while the Arduino has 5V. I couldn't get the example sketches to recognize the Teensy 3.2 SD card reader, but I was able to connect it to my Arduino Mega. SD cards work at 3.3V, so there is a voltage regulator to prevent the 5V signals from Arduino from destroying the SD card. My guess is that the voltage regulator for the SD card reader is limiting the tiny…

To use this on the Nano 33 IOT the VUSB pads on the bottom of the Nano need a drop of solder to connect them together and the Nano needs to go over the mit Power is supplied via USB plug. Otherwise, the 5V pin on the Nano will not supply power. No special code is required and the current standard SD samples will work. The current SPI library for the nano 33 IOT automatically honors the nano's 48MHz clock.

Have been using them for over a year now with no problems. Now I also had to connect the SPI RAM. The SD card is initialized but the RAM is not. I found that the MISO line never goes into tri-state mode. The makers of this board connected the gate enable input (pin 13) of the ALV125A to ground instead of chip select. Desoldering the 13th pin of U1 and connecting to the 8th pin is tricky but possible. This issue exists with other vendors I have reviewed so do not discount the value of these…

I used this for part of a project to generate true random data based on a geiger counter and it is used to back up overflow data. To be honest, this is one of the easiest modules to set up and use that I have ever experienced. I had absolutely no problems and it works fine. It even came pre-soldered which is a big bonus because I'm lazy.

Confirmed to work with ESP 12-E. The pin connections are as follows (left = SD module pin, right = ESP 12-E pin): CS => D8SCK => D5MOSI => D7MISO => D6VCC => Vin (*5v, not 3.3v ) GND => GDN that VCC must be connected to 5V Vin for the module to work (when powered from the USB connector). The NodeMCU documentation says 3.3V, which doesn't seem to be true for this module since the module has a built in voltage regulator that only accepts 5V input. Another thing to note is the…

I use them a lot in my Arduino Uno and Arduino Mega projects. I've used 8GB and 32GB Class 4 or Class 10 microSD cards with no problems when using the Arduino's 5V supply. Although I was able to get them to work with the NodeMCU's ESP8266-based chip, in most cases the initialization step in the sketch failed. I suspect that the 3.3 volts provided by the ESP8266 node MCU is not enough. I will look for ways to power both the ESP8266 nodeMCU and the Micro SD TF card adapter from a 5V power supply…
