If you need to load or store large amounts of data, look no further than this 3.3V SPI microSD card module.

## Pricing

- **Price:** $1.15 (inc GST) — $1.05 AUD, exc GST
- **Quantity discounts:** 25+ $0.99 (exc GST) · 50+ $0.95 (exc GST) · 100+ $0.89 (exc GST)

## Availability & dispatch

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09444:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE09444:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

If you need to load or store large amounts of data, look no further than this 3.3V SPI microSD card module.

The module breaks out each onboard connection to convenient 0.1" headers, add a microSD card, and some jumper wires to connect everything, and get logging!

Perfect for the [Raspberry Pi Pico](https://core-electronics.com.au/raspberry-pi/pico.html) and [ESP32](https://core-electronics.com.au/development-boards.html#category_2184) development boards.

### Specifications

From top to bottom, with the arrow on the silkscreen facing upwards:

1. VCC, 3v3
2. CS
3. MOSI
4. CLK
5. MISO
6. GND
 
### Dimensions

20.8 L x 17.8 W x11.2 H (mm) and without headers 3.7mm Height

### Examples

#### Raspberry Pi Pico - Micropython

Library: [sdcard](https://github.com/CoreElectronics/CE-Makerverse-R2R-DAC-MicroPython-Module/blob/736662d4d0bb810c54242e37fda01cbb2b895bb7/sdcard.py)

 ```
from machine import SPI, Pin
import sdcard, uos

spi = SPI(1,sck=Pin(14), mosi=Pin(15), miso=Pin(12))
cs = Pin(13)
sd = sdcard.SDCard(spi, cs)

uos.mount(sd, '/sd')
print(uos.listdir('/sd'))

# Setup sensors here
adc = ADC(0)
with open('/sd/adcData.txt', "w") as f:
    while True:
        x = adc.read_u16() # Replace this line with a sensor reading of your choosing
        t = time.ticks_ms()/1000
        f.write(str(t)) # Write time sample was taken in seconds
        f.write(' ') # A space
        f.write(str(x)) # Write sample data
        f.write('\n') # A new line
        f.flush() # Force writing of buffered data to the SD card
        print(t, x)
        time.sleep_ms(500)
```
