## 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](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20Raspberry%20Pi%204%20sensor%20hub%20that%20boots%20from%20a%2032%20GB%20microSD%20card%20and%20shows%20BME280%20readings%20on%20an%20LCD): 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](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20temperature%20recorder%20with%20an%20ESP32%2C%20a%20BME280%20sensor%20and%20the%20microSD%20slot%20on%20a%202.8%20inch%20TFT%20display): 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](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20headless%20weather%20station%20on%20a%20Raspberry%20Pi%20Zero%202%20W%20booting%20from%20a%2032%20GB%20microSD%20card%20with%20a%20BME280%20sensor): 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](https://documents.sandisk.com/content/dam/asset-library/en_us/assets/public/sandisk/product/memory-cards/ultra-uhs-i-microsd/data-sheet-ultra-uhs-i-microsd-120mb.pdf))
- Expecting full speed from any host: the quoted speeds are internal-test results and may be lower depending on the host device ([source](https://documents.sandisk.com/content/dam/asset-library/en_us/assets/public/sandisk/product/memory-cards/ultra-uhs-i-microsd/data-sheet-ultra-uhs-i-microsd-120mb.pdf))
- Using a host that only supports older SD cards: the card is microSDHC; the host must support microSDHC / microSDXC ([source](https://documents.sandisk.com/content/dam/asset-library/en_us/assets/public/sandisk/product/memory-cards/ultra-uhs-i-microsd/data-sheet-ultra-uhs-i-microsd-120mb.pdf))

## 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.
