I am relatively new to developing with Arduino and the field of electrical engineering in general so I am looking for a more experienced eye to look over my work to prevent any costly mistakes before they occur (and clear up any confusion I have.)
I have purchased an ATAVRSBIN2 (Datasheet
) and would like it to cooperate with the Arduino (Uno).
I have managed to find one other topic regarding both the ATAVRSBIN2 and Arduino (link
)but I am a bit confused and before I hastily attempt to do something (and ruin something), I want to make sure my setup looks good.
My current strategy (unimplemented) is to use the GND, PWR, SDA and SCL to use I2C with the Arduino.
Question 1: Can I safely use the 3.3V from my Arduino to power the device?
Question 2: Do I need a 4K7 pull-up resistor for the SDA/SCL connections (as specified here
) or am I correct when I read "The I2C pull-up resistors are included on the Inertial Two Sensors Xplained board. " (Top of page 4 in the datasheet).
Question 3: In the article/blog I referenced, the two of them used a "logic level converter" (link
), do I need this and what purpose is it serving? (From my understanding, it's just regulating 5V to 3.3V; which I believe my Arduino board already does for me.)
Thanks in advance, sorry if this board is not intended for this. I tried to be detailed in my questions but if I missed anything, just let me know.
