TX2/TX2i/TX1 Module
- This is level shifted on the Orbitty carrier
to support 3.3V logic.
- Under L4T this port will show up as
/dev/ttyS0
-
This signal is the UART channel 1 output
from the TX2/TX2i/TX1 Module
- This is level shifted on the Orbitty carrier
to support 3.3V logic.
- Under L4T this port will show up as
/dev/ttyTHS2
- This signal is the UART channel 1 input on
TX2/TX2i/TX1 Module
- This is level shifted on the Orbitty carrier
to support 3.3V logic.
-
Under L4T this port will show up as
/dev/ttyTHS2
- This signal is the GPIO Bit 0 and can be
configured as an Input or an Output
- This is level shifted on the Orbitty carrier
to support 3.3V logic.
GPIO KDB
-
This is clock signal on the I2C bus
- This signal has a pull up on the
TX2/TX2i/TX1 module to +3.3V
- Under L4T this is I2C bus # 1
-
This is data signal on the I2C bus
- This signal has a pull up on the
TX2/TX2i/TX1 module to +3.3V
- Under L4T this is I2C bus # 1
- Shorting this signal to Ground will
initialize a system recovery procedure
-
Use this pin to connect a backup battery
source (Coin Cell or other) to sustain the
RTC clock on the TX2/TX2i/TX1 module.
- The voltage should be provided from a 3V
source
