Pinout
We don't publish a pin table for this part: no official source we could verify gives one. Check the labels printed on your module, and see the notes below.
A memory card; this sheet gives no pin table or supply range. Wiring depends on the card socket or breakout used.
Build with it
Project ideas for the SanDisk 32GB microSD card. Each link opens Soldr with the prompt filled in; Soldr assigns the pins, checks power and shows how to wire every part.
- Boot card for a Raspberry Pi 4 sensor hub: The card is the Pi's storage. The BME280 and LCD talk over I2C; check each module's logic level against the Pi's 3.3 V pins before wiring.
- Temperature recorder with the TFT card slot: The card is microSDHC and the board's slot must support that card type; format and slot behaviour are not covered by the card sheet.
- Pi Zero 2 W headless weather station: Card storage holds the system and readings. Operating range of the card is -25 C to 85 C, so keep it out of hot enclosures.
Common mistakes
- Expecting 120 MB/s writes: the sheet states up to 120 MB/s read for the Ultra UHS-I line and that write speed is lower (source)
- Expecting full speed from any host: the quoted speeds are internal-test results and may be lower depending on the host device (source)
- Using a host that only supports older SD cards: the card is microSDHC; the host must support microSDHC / microSDXC (source)
Not covered by the official source
- The exact SanDisk product line and model number of the supplied card are not stated; the Ultra UHS-I sheet is the closest maker document and numbers may differ for other lines.
- Write speed is not given as a number in the sheet.
- Supply voltage and current are not given in the sheet.
