Description-Overview of the Pi-Tron REV001 Demoboard
Serial Interfaces
You need an additional adapter to translate the 3.3V-UART signals (provided on the Mini-USB port) to USB.
Pi-Tron | Used as | Accessible via | Connector |
---|---|---|---|
uart0 | Console; TTL; RS485 | /dev/ttyAMA0 /dev/serial0 |
X800 |
uart1 | Console; TTL; RS485; RS232 | /dev/ttyS0 /dev/serial1 |
X900 |
IOs
Four digital inputs/outputs (either or) are available. If used as output the state can be read back from the associated input.
The table below shows number and function of available GPIOs.
The Input/Output Voltage are coupled with the Power-Supply-Voltage. Normaly 24V. The maximum output current of each Port is 110mA depending on the power supply. On the Inputs all values over 6V are high and all values under 4V are low.
