 Congratulations! You was able to run WebHMI on your Raspberry Pi 3. Have fun with it.
+===== SCADA hat =====
+To make RPi users' life a bit easier we developed a special SCADA hat. This board includes:
-====== Troubleshooting ======
+  * Power supply with filters (Input voltage: 9...30V)
+  * RS-485 converter with optional galvanic isolation
+  * Real-time clock with CR2032 battery backup
+{{ network:7bit-power-hat.jpg?nolink |}}
+With this extension board it is very easy to try all WebHMI's features in near to real-life environment: you can connect it to the same 24V power supply and connect to RS-485 devices. There is no need to use weak microUSB 5V phone chargers, and inconvenient USB RS485 adapters.
