Ever wanted to have two hardware Serial Ports, two SPI, two I2C and more PWM pins on the Arduino Pro Mini? Tit has all of this, and retains the same form factor. Tit uses Atmega328PB at its core.

Tit, is pin compatible with Arduino Pro Mini, the chip Atmega328pb is software compatible with Atmega328p. Hence all the existing code and libraries should work without any changes. Tit uses higher version of avr-gcc toolchain, we have bundled it up as a package along with additional libraries required to access the extra features.

Check this detailed tutorial on setting up Tit for different operating systems.

  • PWM x 9
  • Interrupt Pins x 2
  • Unique HW ID
  • Castellated Pads
  • Pin compatible with Arduino Pro-Mini

Project Status

  • Tool chain tested on windows and linux 64 bit systems. Please check the project in reference section for more details on this.
  • PCB designed in KiCAD and firmware is up and running
  • Bootloader, both UARTs, i2c, additional PWMs and all GPIOs have been tested.

To Do:

  1. Test the tool chain on MAC and linux 32 bit
  2. Test additional SPI and I2C interfaces
  3. Library for accessing unique hardware id of the device.

@Hans Olo Thanks, the price will be between $6 to $9. Not decided it, we have got the PCBs and passives waiting for the chip.  

  Are you sure? yes | no

Very nice, but where can I actually buy one?

  Are you sure? yes | no
