Lets see where do I start. So today there is a pretty big update to the three piece of hardware that I have been working/talking about related to HydroPWNics. The first big update was to the Module Hub, I reworked it to support only 3 modules BUT now it sports a ESP8266 ESP-12E WiFi module and a smaller size (cheaper PCB yay). IN addition to the smaller size and WiFi, the board has my resized M3 screw holes and 1/4 radius rounded corners. The MKV10 ARM will talk to the ESP-12E module over SPI, streaming the latest readings off the modules to the cloud. Also one lat thing that was added were neat Hackaday Prize logos :) . The New Module Hub:

Module Hub WiFi Spec:

- MKV10Z16VFM7 - 32 Pin QFN 5X5

- 3 Module Ports with 12VDC Power

- ESP8266 ESP-12E WiFi Module

- On Board DCDC 3V3 regulator for 1A 3V3 DC Power

- On Board DCDC 5VDC regulator for 1A 5V DC power (level shifter/expansion)

- ARM Cortex M JTAG Debug Connector

- 74HC4052 Analog Multiplexer Demultiplexer for UART module Interfacing

- 4 M3 Screw Mounting holes

Next on we have the updated sensor modules. Not much has changed with the sensor modules since I posted their revised versions a few days ago. The major change to both modules is the addition of 1/4 inch radius rounded corners (to make all the boards "match") and the subsequent remodeling of the topology to fit everything on the modified shape. Additionally open hardware and hackaday prize logos were added to the modules. With out further due the new modules:

So far the hardware of the project has been moving very quickly, the next step will be making comprehensive BOMs for each of the boards then off to the fab, thinking OSHPark but might try something new. When the current set of modules are ready for fab I will be moving on to the closed loop control board since it will be used in quite a few places on the project. Stay tuned for more hardware and updates!
