databot™ Basic Training
databot™ is an open book for programmers, power users, inventors, Makers, and more. Learn to go deep with our Deep Geek docs!
A Deep Dive into databot™ Hardware!
databot™ is built on an open hardware on ESP32 and software platform called Arduino. The following technical details are provided for those of you techies out there that want to take control of databot™ at the hardware level and program your own awesome applications. Here you will find:
- Digital Port Map
- Analog Port Map
- I2C Addressing for Modules
- Detailed Sensor Data Sheets
- Pinout Design for Connecting Your Own Sensors to databot™
If you are new to Arduino programming, or Arduino in general, we recommend you go through our free introduction to Arduino that will give you some good background on what it is all about. It also provides some great links for resources for you to get started on your own Arduino programming journey.
One final, and very important note for you geeks before you dive in, the design and voltage regulator is a 3V3 system within databot™. ALL signals and voltage input from third party devices must be 3V3 or converted to 3V3. For those of you who have burned up a component or two, you will know what we are talking about!
Fortunately, there is an easy solution to this challenge, and it is provided by the awesome geeks at Sparkfun, who like hacking just as much we do. Check out their Bi Directional Logic Level Converter and read through the detailed hookup guide to learn more. This converter, combined with the world of sensors out there, should give you many, many possibilities for expanding databot™.
Good luck and have fun!

Connector Pin-Outs
Expand your databot™ world with I2C!
I2C is a communications protocol that is widely used in the world of electronics. If you do a quick Internet search for I2C sensors you will see many types of sensors that you might be able to connect to databot™! In addition, there are a number of other devices that use I2C that you can connect with such as a Raspberry Pi, MicroBit, or others.
At the side of databot™ is an open USB Micro-B port that provides the I2C protocol for you to experiment with. This enables you to connect all kinds of sensors and devices.
Use the Pinout diagram to the right to build your own I2C connections for new sensors you dream up.
databot™ UART Communication
The other open expansion port on the left side of databot™ is a open USB Micro-B port. This UART USB Micro-B port provides a hardware communication protocol that uses asynchronous serial communication with configurable speed. Asynchronous means there is no clock signal to synchronize the output bits from the transmitting device going to the receiving end.
Like I2C, if you do a quick Internet search for UART Communication for ESP32, you will be overwhelmed with the possibilities!
Use the Pinout diagram to the right to construct your direct databot™ connection to other devices with UART such as the Sphero RVR, LEGO® EV3 and Spike, etc.
Let your imagination run wild!
Congratulations!
You have successfully completed an exploration of the remarkable capabilities at your fingertips for programming and modifying databot™ to study the world around you and explore data. Now comes the fun part, challenge yourself to begin programming and inventing with databot™. Can you invent something that will make a better world?! Have fun!
