Page 3: Overview
SMD packages. Features Compatible with Arduino boards. • Drives 4 IV-3 VFD tubes. • Power supply 12V DC + 5V DC (via Arduino board, 12V supply needs to be • stabilized). Enclosure design (CAD files) available. • Applications Clock. -
Page 4: Assembly Hints
Power supply The IV-3 VFD shield needs the Arduino to be powered from a 12 V DC power supply to function properly. Use only a regulated switching power adapter capable of delivering 12 V DC / 300 mA. -

It is recommended to solder C6, C7 and C8 from the component side and to trim the leads as short as possible on the solder side as they are positioned above the metal shield of the Arduino USB connector. Assembly Manual... -
Page 8: Ceramic Capacitors
IV-3 VFD shield for Arduino Ceramic capacitors Mount following ceramic capacitors: C1: 2n2 • C2, C3: 8n2 • C4: 100n • Please note that the values of C1...C3 are somewhat critical as C1 defines together with R5 the operating frequency of the voltage... -
Page 9: 220K Resistors
IV-3 VFD shield for Arduino 220K resistors Mount the 220 kilo ohm resistors (red – red – yellow – gold) R43...R54. Mount them vertically as in the picture. 100K resistors Mount the 100 kilo ohm resistors (brown – black – yellow – gold) R31...R42. -
Page 10: Arduino Headers
Arduino stackable headers. The headers will not really be used to stack other Arduino shields on top of this shield but they help to determine the mounting height of several components and the IV-3 tubes. Push the headers through the PCB and plug them in your Arduino. -

D9 to avoid them touching the ISP connector on the Arduino. The LEDs are connected to a PWM output on the Arduino and can be dimmed using software. This will however not work properly when you use RGB color fading LEDs. -
Page 12: Vfd Tube Mounting
IV-3 VFD shield for Arduino VFD tube mounting Guide tube wires gently through their respective holes on the PCB. Make sure the short lead on the tubes goes through the hole without solder pad. Now the digits should face the front of the PCB. -
