IoTuz - The Internet of Tuz

Welcome to the 2017 Open Hardware Project. You can see information about this and other MiniConfs at

This year we're bringing a project with the hottest new micro for people to have a play with. The ESP32 is the successor to the hugely popular ESP8266 chip we used for 2016 Open Hardware Project, the (ESPlant, CCHS-Melbourne/ESPlant).

The ESP32 is definitely the big brother of the ESP8266. Included in it's features: 2.4 GHz Wi-Fi, Bluetooth, Dual Core CPUs

As usual we've got a custom board and some custom software to get you started on your journey! Check out the subdirectories in this repo for more information.

IoTuz firmware can be found at CCHS-Melbourne/iotuz-esp32-firmware

Software instructions

Software setup instructions

Please see marcmerlin/IoTuz mentioned below for an arduino driver.


Marc MERLIN has written a driver for the arduino environment with support for:

  • TFT (hw SPI)
  • Touchscreen (hw SPI)
  • Replacement touchscreen support (calibration option in case your touchscreen is reversed or has different calibration)
  • Rotary Encoder via pin interrupt driven driver
  • Support for A and B buttons "hidden" behind the I2C IO multiplexer
  • Joystick
  • Color LEDs
  • Accelerometer
  • BME280 (temperature, humidity, pressure)
  • IO expander (pcf8574)
  • Infrared receiver

Getting IoTuz

You need to clone the IoTuz repo from github, using the --recursive option to pick up submodules. If you download a zip file then the submodule parts will be missing, so we recommend using git to get it.

The command is:

git clone --recursive

Where to Now?

Check out (and contribute to) the wiki. There is a pinout summary, sensor summary, power information, etc.
