Introducing Luminardo

Luminardo was specifically designed to work together with Vacuum Fluorescent Display (VFD) panels such as MVFDPanel 16S8D. One of the most distinctive features of Luminardo is its low profile. The board also shares same dimensions with VFD module so the final product looks very compact and unusual, it could be easily embedded into a car dashboard or something similar. Currently there is only one type of VFD module with more yet to come – all of them will be sharing the same form factor making possible to evolve the project into something like Lego. Luminardo is a flexible solution, it comes with USB client, USB host, I2C, SPI, ISP, 1Wire and Serial interfaces. Having USB host onboard means that the board is easily integrated with huge variety off-the-shelf devices such as USB sticks, USB hard drives, Bluetooth, WiFi and so on. The board also has a connector for PIR sensor, a battery backed up RTC, an embedded temperature sensor with possibility to connect external 1Wire devices. Obviously there is an option to connect extension boards (or shields) building more complex and sophisticated systems. The board can be powered either off unregulated 12V or 5V (USB) interface. There is a way to power it off an alternative source of energy, for instance, solar/lithium battery shield of even something more exotic.

The circuit diagram of the motherboard is given below.

The PCB layout is done on two layers with dimensions less than 100mm x 27mm which allows to be within limitations of ‘light’ Eagle license and take advantage of 100mm x 50mm PCB manufacturing service from ITead Studio. Component placement for top and bottom sides are given on the pictures below.

A 3D model of the PCBA is available in Google 3D Warehouse.

ATMega source code is yet to come – stay tuned.

Note that originally this project was named ‘FluoroDuino’ and later it was renamed to ‘Luminardo’ so please don’t be surprised when you download Rev.1.0 design files – there is still the old name.
