# USB to TTL Serial Cable

**Type:** Product page · **SKU:** CAB-12977 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/usb-to-ttl-serial-cable.html ([markdown](https://core-electronics.com.au/usb-to-ttl-serial-cable.html.md))

This is a USB to TTL Serial Cable which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this cable are configured to operate at 3.3V specifically with a Raspberry Pi with each serial pin broken apart. Thanks to its separated pins, this cable is a perfect candidate for powering, connecting, and accessing the login and debug console on the Raspberry Pi.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CAB-12977:1` (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/CAB-12977:1.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

This is a USB to TTL Serial Cable which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this cable are configured to operate at 3.3V specifically with a Raspberry Pi with each serial pin broken apart. Thanks to its separated pins, this cable is a perfect candidate for powering, connecting, and accessing the login and debug console on the Raspberry Pi.

The FTDI cable is designed around an FT232, which is housed in a USB-A connector. The other side of the cable is terminated with a separated 4-pin connector with the following pinout: RX (Brown), TX (Tan-like/Peach), VCC (Red), and GND (Black). A link to the FTDI drivers can be found in the *Documents* section below.

### Specifications

- The cable is 2M long

**Note:** Please be aware that while the I/O pins in this cable operate at 3.3V, the VCC pin is 5V. The VCC pin is NOT 3.3V like the I/O pins.
