I would like to share a new version of my 8 port controller PCB The actual 8 port extension chip have been removed to make a bit more space for some new additions so i have now called it "just" the uMite controller board. This new PCB was prompted by my (Caravan) Battery Status Meter but is in no way restricted to that project.  New Options Backlight control or Fixed UNIO eeprom Input Supply Voltage divider Half Vcc Voltage divider "Microbridge" serial interface/programmer Based on MX170 SOIC device ILI9341 LCD display support RTC module ESP8266 wifi module General 8 Pin connector, 6 general mixed Input/Output/Analog plus 3.3v and Gnd Ext I/O 8 pin connector, console , spi, I2c ICSP connector Console connector Mounting for two regulator types Pololu PSU module (3.3v), you can choose to use best one for your needs ie stepup, stepdown, or stepup/stepdown variety. "Tiny DC to DC" Reg variable output 2.5-5V (set to 3.3v) Input 2.5-28V Gerbers etc are here Codenquilts |

I received my PCBs back and have now built one up. Really pleased with this one, it is the 4th version in the series (its has taken me that long to get the inclusions correct and rid of silly errors, even saying that I still have a silk screen error!) The "Microbridge" addition is fantastic, thanks to all. For my projects I think it is now a very useful little board. I can understand why Big Mick, Grogster and others are such prolific PCB makes , its really addictive  Shown here without the LCD, with WiFi integration, UnI/O, backlight control, Tiny DC/DC PSU installed 4.5-28v 1A  I interface to most of my projects via a WiFi interface I have developed over last 2 years, data retrievable via HTTP,UDP,email,IOT etc, two way messaging/control there is also a simple Web I/F if required, my Weather Station shown.
