JetHome Jethub D2 is a home automation controller with the following
features:
- DIN Rail Mounting
- Amlogic S905X3 (ARM Cortex-A55) quad-core
- micro-HDMI video out
- 4GB LPDDR4
- 32GB eMMC flash
- 1 x USB 2.0
- 1 x 10/100/1000Mbps ethernet
- two module slots for radio/wire interface cards
- 2 x gpio LEDS
- 1 x 1-Wire
- 1 x RS-485
- 3 x dry contact digital GPIO inputs
- 2 x relay GPIO outputs
- DC 9-36V power source with battery UPS on board option
