Introducing Vine-K !!!!

A project log for Agricoltura - IO

A connected control system for all agriculture applications based on RS485 control nodes and multiple wireless sensor networks

Hey folks, been hard at work developing all the hardware in this new ecosystem, tonight I have a new device to introduce, Vine-K. K is the universal designator symbol relays or contactors and if you can follow where I'm going with this Vine-K is a version of the Vine board that has more relays and is focused on high voltage switching applications in connected agriculture applications. VIne-K still keeps the 5V GPIO header for a bit of addons and hack prototyping, it didn't make sense to not give it a little bit of IO capability. 

The gist of Vine-K is the same architecture and board size as the standard Vine board but with 5 relays and 8 5V GPIOs on a single header, quick specs are as follows:

- ST Microelectronics STM32F446RET6 ARM Cortex M4F 180MHZ MCU
- 5V Tolerant Analog Inputs
- 8x I2C interfaces
- 4x UART interface (via mux)
- 8x 5V digital IO ports
- 2x G5LE-14 DC5 SPDT Relays
- USB 2.0 connectivity
- RS485 port
- 24VAC power input
- 2A 3.3V DCDC Regulator, for supporting lots of sensors
- 2A 5V DCDC Regulator, for 5V IO and other devices

I am also excited to say that both the schematic and PCB for this board are fully complete with possible tweaks down the road. I also updated the original Vine to have dedicated connectors for the relays like Vine-K has only made sense to keep things consistent. Without further ado here is Vine-K

As with my personal hackaday prize tradition I am moving very fast and this is only the 2nd of many boards to come. While working on Vine-K I started laying out the schematic for the gateway/controller which I am calling madre at the moment. First Madre will be a cape for the beaglebone green, this will allow much quicker development of the prototype, once the design is confirmed I will be rolling a complete custom PCB using the Octavo Systems Beaglebone in a chip System In Package to make it all one board. Quick specs of madre are as follows:

- Seeedstudio Beaglebone Green
- 4x RS485 ports
- Sub 1GHZ wirless modem with SMA Antenna Connector
- 2.4GHZ wireless model with SMA Antenna connector, supporting all 2.4G types
- WiFi modem with SMA antenna connector
- 1x USB 2.0 ports
- USB serial monitor connection
- Ethernet

Stay tuned for more updates on the Agricoltura IO project and family of connected hardware, we are rolling hard and fast , its gonna be a good summer!!

Lets Rock!!!!
