# microSD Sniffer

**Type:** Product page · **SKU:** TOL-09419 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/microsd-sniffer.html ([markdown](https://core-electronics.com.au/microsd-sniffer.html.md))

When playing with microSD, you sometimes need to view what the SPI traffic is doing, whether for hacking or debugging. The microSD Sniffer allows you to hook up an external device, such as a logic analyzer or microcontroller, to view what signals are being passed back and forth. Insert one side into a regular uSD socket and a uSD card into the on-board socket, simple as that.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=TOL-09419:1` (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/TOL-09419:1.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)

When playing with microSD, you sometimes need to view what the SPI traffic is doing, whether for hacking or debugging. The microSD Sniffer allows you to hook up an external device, such as a logic analyzer or microcontroller, to view what signals are being passed back and forth.

 All necessary pins are broken out to an 8-pin 0.1" pitch header.
