Block schematic

Today post will be short, just about the schematic. Software and codes will be in future posts.

Arduino pro mini

You can get one here for cheap.

I choose Arduino pro mini because it’s size and price. It is really fast, easy to program and low power consumption.

FT232RL TTL USB Serial

I used this FT232RL TTL USB Serial. I use a serial port to get data from Arduino pro mini and send RTC signal at power up from Orange Pi Zero

.

OrangePi Zero

I used this OrangePi Zero. Because is cheaper than Rasberry Pi Zero, with almost same performance and got WiFi, uses Raspbian and also support Node.js.
