# Adafruit DS2482S-800 8 Channel I2C to 1-Wire Bus Adapter ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/132/364/medium800/adafruit_products_6027-04.jpg?1726587827) The [DS2482S-800](https://www.analog.com/en/products/ds2482-800.html) is a Stemma QT board that uses a I2C-to-1Wire controller chip, with 8 selectable channels, built-in parasitic-power-pullups, adjustable I2C address and a wide operating voltage range! You can easily connect it to an existing I2C bus and then use the breakout pads to attach multiple DS18B20's, or pair it with our [1-Wire chaining breakouts](https://www.adafruit.com/product/5971) for fancier experimentation. ![](https://cdn-learn.adafruit.com/assets/assets/000/132/365/medium800/adafruit_products_6027-02.jpg?1726587874) You're probably familiar with the 'top three' electronics protocols: I2C, SPI and UART. Perhaps you're aware of a fourth one, [called "1-Wire" which was invented by Dallas Semiconductor](https://www.analog.com/en/resources/technical-articles/guide-to-1wire-communication.html) (which became Maxim, which became Analog Devices). As you may expect, this protocol uses a single data wire plus a ground wire (and an optional power wire) to connect to any number of sensors or memory chips that all share the same bus. ![](https://cdn-learn.adafruit.com/assets/assets/000/132/366/medium800/adafruit_products_6027-03_%281%29.jpg?1726587916) In theory, there's a lot of different 1-Wire devices out there, but in reality almost everyone uses 1-Wire for DS18B20 temperature sensors. the long wire lengths and ease of 'chaining' by sharing a single bus wire makes it perfectly fine for this purpose. You can bit-bang 1-Wire on most microcontrollers, and some SBCs like [Raspberry Pi have kernel module support](https://learn.adafruit.com/adafruits-raspberry-pi-lesson-11-ds18b20-temperature-sensing). But are lots of chips or firmware stacks without 1-Wire capability, or maybe you want to use 1-Wire devices on your desktop computer or other SBC with I2C. ![](https://cdn-learn.adafruit.com/assets/assets/000/132/367/medium800/adafruit_products_6027-01.jpg?1726587958) You might be wondering: if you can connect multiple 1-Wire devices on a single wire, then why have 8 channels on this breakout? Reason is: if you have 8 temperature sensors, there's no easy way to know which one is which other than connecting them one at a time and reading the unique ROM identifier. With this breakout you can select the channel so you know for sure which location is being measured, even if the sensor is swapped out later. ![](https://cdn-learn.adafruit.com/assets/assets/000/132/368/medium800/adafruit_products_6027-00.jpg?1726587985) To get you going fast, we spun up a custom-made PCB in the [**STEMMA QT** form factor](https://www.adafruit.com/?q=stemma%20qt%20sensor "STEMMA QT form factor"), making it easy to interface. The [STEMMA QT connectors](https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma-qt) on either side are compatible with the [SparkFun Qwiic](https://www.sparkfun.com/qwiic) I2C connectors. STEMMA QT allows you to make solderless connections between your development board and the DS2482S-800 or to chain it with a wide range of other sensors and accessories using a [**compatible cable**](https://www.adafruit.com/?q=stemma%20qt%20cable). You can power the board directly from the STEMMA QT cable, whether 3V or 5V, that voltage will also be the power output for the 1-Wire peripherals. # Adafruit DS2482S-800 8 Channel I2C to 1-Wire Bus Adapter ## Pinouts ![](https://cdn-learn.adafruit.com/assets/assets/000/132/372/medium800/adafruit_products_double.jpg?1726589390) The default I2C address is **0x18**. ## Power Pins - **VIN** - this is the power pin. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V. - **GND** - common ground for power and logic. ## I2C Logic Pins - **SCL** - I2C clock pin, connect to your microcontroller's I2C clock line. This pin can use 3-5V logic, and there's a **10K pullup** on this pin. - **SDA** - I2C data pin, connect to your microcontroller's I2C data line. This pin can use 3-5V logic, and there's a **10K pullup** on this pin. - **[STEMMA QT](https://learn.adafruit.com/introducing-adafruit-stemma-qt) -** These connectors allow you to connect to development boards with **STEMMA QT** (Qwiic) connectors or to other things with [various associated accessories](https://www.adafruit.com/?q=JST%20SH%204). ## 1-Wire Header Pins At the top edge of the board are 8 1x3 header pins. These pins let you connect 8 different 1-wire sensors to the breakout board. Each set of 3 pins ( **+** , **1W** and **-** ) are labeled 0-7. These labels denote the channel number that you'll use in the code. - **+ ** - the power connection for the 1-wire sensor. It shares the same voltage level as **VIN**. - **1W** - the signal connection for the 1-wire line - **-** - the ground connection for the 1-wire sensor ## Address Pins On the back of the board are **three address jumpers** , labeled **A0** ,  **A1** , and **A2**. These jumpers allow you to chain up to 8 of these boards on the same pair of I2C clock and data pins. To do so, you solder the jumpers "closed" by connecting the two pads. On the front of the board are **two address pins** , labeled **A0** and **A1**. Just like the jumpers, these pins allow you to change the I2C address to connect multiple boards by connecting them to **VIN**. **There is no broken out pin for A2**. The default I2C address is **0x18**. The other address options can be calculated by "adding" the **A0/A1/A2** to the base of **0x18**. **A0** sets the lowest bit with a value of **1** , **A1** sets the next bit with a value of **2** and **A2** sets the next bit with a value of **4.** The final address is **0x18 + A2 + A1 + A0** which would be **0x1F**. So for example if **A**** 2 **is soldered closed and ** A ****0** is soldered closed, the address is **0x18 + 4 + 1 = 0x1D**. 
If only **A0** is soldered closed, the address is **0x18 + 1 = 0x19** 
If only  **A**** 1 **is soldered closed, the address is** 0x18 + 2 = 0x1A** 
If only  **A**** 2 **is soldered closed, the address is** 0x18 + 4 = 0x1C** The table below shows all possible addresses, and whether the pin(s) should be high (closed) or low (open). ![](https://cdn-learn.adafruit.com/assets/assets/000/132/373/medium800/adafruit_products_Screenshot_2024-09-17_122018.png?1726590104) ## Power LED and Jumper - **Power LED** - on the left side of the board, above the STEMMA QT connector, is the power LED, labeled **on**. It is the green LED. - **LED jumper** - on the back of the board is a jumper for the power LED. It is labeled **LED** on the board silk. If you want to disable the power LED, cut the trace on this jumper. # Adafruit DS2482S-800 8 Channel I2C to 1-Wire Bus Adapter ## CircuitPython and Python It's easy to use the **DS2482S-800** with Python or CircuitPython, and the [Adafruit\_CircuitPython\_DS248x](https://github.com/adafruit/Adafruit_CircuitPython_DS248x) module. This module allows you to easily write Python code to read 1-Wire sensors over I2C. You can use this driver with any CircuitPython microcontroller board or with a computer that has GPIO and Python [thanks to Adafruit\_Blinka, our CircuitPython-for-Python compatibility library](https://learn.adafruit.com/circuitpython-on-raspberrypi-linux).

This may also require enabling I2C on your platform and verifying you are running Python 3. [Since each platform is a little different, and Linux changes often, please visit the CircuitPython on Linux guide to get your computer ready](https://learn.adafruit.com/circuitpython-on-raspberrypi-linux)! Once that's done, from your command line run the following command: - `pip3 install adafruit-circuitpython-ds248x` If your default Python is version 3 you may need to run 'pip' instead. Just make sure you aren't trying to use CircuitPython on Python 2.x, it isn't supported! ## CircuitPython Usage To use with CircuitPython, you need to first install the **Adafruit\_CircuitPython\_DS248x** library, and its dependencies, into the **lib** folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script. Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, and copy the **entire** **lib** **folder** and the **code.py** file to your **CIRCUITPY** drive. Your **CIRCUITPY/lib** folder should contain the following folder and file: - **adafruit\_bus\_device/** - **adafruit\_ds248x.mpy** ![CIRCUITPY](https://adafruit.github.io/Adafruit_CircuitPython_Bundle/ds248x_ds248x_simpletest.py.png ) ## Python Usage Once you have the library `pip3` installed on your computer, copy or download the following example to your computer, and run the following, replacing **code.py** with whatever you named the file: `python3 code.py` ## Example Code **If running CircuitPython:** Once everything is saved to the **CIRCUITPY** drive, [connect to the serial console](https://learn.adafruit.com/welcome-to-circuitpython/kattni-connecting-to-the-serial-console) to see the data printed out! **If running Python:** The console output will appear wherever you are running Python. https://github.com/adafruit/Adafruit_CircuitPython_DS248x/blob/main/examples/ds2482s-800_8-channel_test.py First, the DS2482S-800 is instantiated over I2C. In the loop, each of the 8 channels is selected and read. The selected channel and its temperature reading are printed to the serial console. If you don't have a DS18B20 sensor attached to a channel that is read, a negative value of -0.06 will be printed to the console. The print out below shows data on channels 0 and 4. ![](https://cdn-learn.adafruit.com/assets/assets/000/132/379/medium800/adafruit_products_Screenshot_2024-09-17_151336.png?1726600428) # Adafruit DS2482S-800 8 Channel I2C to 1-Wire Bus Adapter ## Python Docs # Adafruit DS2482S-800 8 Channel I2C to 1-Wire Bus Adapter ## Arduino Using the DS2482S-800 breakout with Arduino involves wiring up the breakout to your Arduino-compatible microcontroller with two DS18B20 sensors, installing the [Adafruit\_DS248x](https://github.com/adafruit/Adafruit_DS248x) library, and running the provided example code. ### DS18B20 Digital temperature sensor + extras [DS18B20 Digital temperature sensor + extras](https://www.adafruit.com/product/374) These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter.
