Gateway PCB is in fabrication, and I'm hoping for the best that there

will be no errors on PCB. It will have following parameters:

• MCU ATmega1284P, 16KB RAM, 128KB Flash.
• 8 analogue inputs for balanced PIR sensors.
• 4 digital inputs for simple sensors, like door/window reed switches.
• 1 box tamper input.
• TWI/I2S expansion connector for up to 4 additional 8 channel analog inputs.
• 2 relay outputs with selectable 12V power out.
• RS485 protected interface for wired nodes.
• RFM69HW for wireless nodes and sensors, pigtail and rubber antenna.
• W5500 10/100Mbps Ethernet for web interface and MQTT.
• SIM900 GSM modem for SMS alerting, pigtail and rubber antenna.
• RTC clock with separate battery backup with NTP synchronization.
• 512kb EEPROM as logger
• Power Off and Empty battery inputs.
• Standard FTDI Arduino programming interface.

I have been so bold that I put it on pre-order in the BUY section for 72EUR or 79USD.
