May I add new sensors in Ultimaker 2 or UM2+?

[disilva 0]

Hi all,

 

I want to buy a Ultimaker 2 or Ultimaker 2+ 3D printer for university projects but I need to know if this 3d printer has unoccupied digital/analog ports for adding new sensors (as more endstops or semaphore with leds), or if I can extended the actual ports to introduce more. 

 

Thanks in advance.

The schematics are published on Github:

https://github.com/Ultimaker/Ultimaker2/tree/master/1091_Main_board_v2.1.1_(x1)

 

There are a few unused Arduino pins exposed on headers on the main board (J22 - J26 and on EXP1 or EXP2 too).

For more ambitious projects it's probably even possible to add more devices to the existing I2C bus (in addition to display and encoder led), but i have not seen that yet.

Thank you a lot! It is exactly what I need it! 🙂

 

I'm embarrassed because I found this github repository but i lost myself with the folders...

 

Thank you again.
