# Line Follower Board

**Type:** Product page · **SKU:** KT-5337 · **Brand:** [Kitronik](https://core-electronics.com.au/brands/kitronik-australia)
**Page:** https://core-electronics.com.au/line-follower-board.html ([markdown](https://core-electronics.com.au/line-follower-board.html.md))

Add precise line following to your autonomous buggy builds with the Kitronik Autonomous Robotics Platform Line Follower Board.

## Pricing

- **Price:** $7.70 (inc GST) — $7.00 AUD, exc GST
- **Quantity discounts:** 10+ $6.72 (exc GST) · 25+ $6.51 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=KT-5337:1` (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/KT-5337:1.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

The Kitronik Autonomous Robotics Line following sensor board allows you to add line following to your robot/buggy projects. The board features 3 phototransistors that adjust the current flow depending on how much reflected light they detect. This results in an analogue output voltage that can be read into a microprocessor’s ADC channel, such as the [Raspberry Pi Pico](https://kitronik.co.uk/collections/coding/products/5330-raspberry-pi-pico-with-pre-soldered-headers). It is also possible to use this board with other microprocessor platforms, such as the [BBC micro:bit](https://core-electronics.com.au/micro-bit-v2-australia.html) and [Arduino](https://kitronik.co.uk/collections/arduino/products/5320-maker-uno-maker-uno-simplifying-arduino-for-education). This board also features in the [Kitronik Autonomous Robotics Platform for Raspberry Pi Pico](https://kitronik.co.uk/products/5335-autonomous-robotics-platform-for-pico).

The 5 pin connections are on a standard 0.1” (2.54mm) pitch pin header that will fit any standard prototype breadboard or strip-board. The pins provide connections for power (3v and 0V) and 3 sensor outputs, marked L, C, and R for the left, centre and right sensors respectively.

The board requires a 3V-5V supply (nominal 3.3V) and a ground connection onto the pin header. These pins are marked on the board as 3V and 0V. For more details on the pinouts see the [Datasheet](https://core-electronics.com.au/attachments/localcontent/5337-line-following-sensor-board-datasheet_35942bfc0fc.pdf) electrical information.

The sensor outputs a voltage that will change from the supply voltage to 0V. This change occurs when the sensors pass over light and dark surfaces. Different surfaces will reflect different amounts. A typical light surface will give a value of 0.5V for example. A typical dark surface will give a value of 2.5V (assuming a 3V VCC). The value in a program will depend on the processor's ADC range and width.

| Surface. | Response. |
|---|---|
| Light. | Low Voltage ˜ 0V |
| Dark. | High Voltage ˜ 3V |

For an example of how to write code for this board, we have produced [MicroPython](https://micropython.org/) example code, which you can [find here](https://github.com/KitronikLtd/Kitronik-Pico-Autonomous-Robotics-Platform-MicroPython). This MicroPython code has been written to demonstrate coding for the [Raspberry Pi Pico](https://kitronik.co.uk/collections/coding/products/5330-raspberry-pi-pico-with-pre-soldered-headers). It is also possible to use this sensor board with an [Arduino](https://kitronik.co.uk/collections/arduino/products/5320-maker-uno-maker-uno-simplifying-arduino-for-education) or a [BBC micro:bit](https://core-electronics.com.au/micro-bit-v2-australia.html). For more information, please refer to the [Datasheet](https://core-electronics.com.au/attachments/localcontent/5337-line-following-sensor-board-datasheet_35942bfc0fc.pdf).
