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!!!!
