Hello,
While T16M board doesn't explicitly have I2C and UART connectors as per the product description, I was wondering if using GPIOs can be a way to have I2C and UART interfaces.
The documentation says GPIO ports exposed on screw terminals (GPIO8, GPIO9, GPIO10, GPIO15, GPIO16, GPIO17, GPIO18) have pull-up resistors and can be used for 1wire sensors.
My questions are:
1. What is the pull-up resistor value? 4.7k?
2. Is there ESD protection diode for these pins?
3. Can these GPIOs be used for I2C and UART? (typically: GPIO8 and GPIO9 for I2C, GPIO16 and GPIO17 for UART)
