A13 SoM open hardware - PLC alike - smart home server

[boernsman]

Hey folks,

me and my team from guh have developed an open source smart home software called guhIO. github.com/guh/guh/wiki
Last week I've setup a new project named guhPLC. It's not realy a PLC it is more a hardwired smart home server. It is mainly designed for single-famility house builders - it can be mounted on DIN rails like you can find in an electrical cabinet.

Specs:

• A13 SoM
• LAN - ENC28J60
• STM32 Microcontroller
• 24V DC IN
• 8 Digital In - 24VDC
• 8 Relay - 5A/240V AC
• 4 Analog In 0-10V
• 4 Analog Out 0-10V 20mA
• RS-485

You can get the schematic and board files at https://github.com/guh/guhplc

Check it out! 

Cheers,
Bernie
