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

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 boards. Just be warned.
