I2C 1.8v use 3.3v
I have a PN532 module that operates at 3.3V for I2C communication. However, the I2C on my LattePanda runs at 1.8V. To address this, I connected the 3.3V pin from the nearby I2S to the PN532, while the GND is shared with the I2C GND from LattePanda.
Currently, the PN532 indicator light is on, but I am concerned about whether this setup could potentially damage the I2C or I2S ports on my LattePanda, considering the voltage differences.
Could you confirm if this wiring could cause any issues or damage to my LattePanda, or if there is a safer alternative to ensure proper communication between the devices?
Looking forward to your advice.
