Overview
VFD Power is an open-source printed circuit board by mariosgit, from the mariosgit/VFD repository on GitHub, published under the MIT licence. It is a 2-layer board of 83.5 × 27.9 mm with 24 parts on 17 nets, routed with 164 tracks and 31 vias.
It is built around the XL6009, ZXBM5210-S and 74132DC, with the DR125 among its other parts. Its parts include 8 capacitors, 5 resistors, 3 ICs, 3 inductors and 2 diodes. It belongs with the lEDs and displays boards of this library.

Reminder
To edit a schematic/pcb, open the .pro file first (double click) KiCad needs this to handle sch/pcb together, otherwise u get wiered errors when updating pcb from schematic.

A Panel with that display and an Teensy4.
Intended Use: Graphical EQ. The bottom PCB is a FreeDSP-AllInOne.
- Infopage https://freedsp.github.io/
- Github: https://github.com/freeDSP/freeDSP-ALLinONE
Contains
- Power for VFD (~3V fillament, 30-50V for anode and grid) and 5V for other stuff.
- Teensy4 - Controls the Amp and shows vintage spectrum analyser.
- 2 Encoders
- 5 Buttons.
Status
Tested, has bugs... Can be patched to work somewhat.
Bugs
- VFD pin 9 (TEST) must have 100k pullup to 3.3V and small buffer C.✅
- SDA/SCL are twisted ! ✅
- PL(atch) is not connected to ATTiny ! Removed ATTiny ✅
- ATTiny fliegt raus, zu umstaendlich.✅
- I2S pins wrong, fixed + SRCs ✅
- 5V reg wrong footprint (from a kicad lib)
- Add revision info
- Crosscheck wiring with proto
Bugs
- RECOM 5V reg wrong footprint (from a kicad lib)
- VFD pin 9 (TEST) must have 100k pullup to 3.3V and small buffer C.
Todo
-
Test audio connection to/from teensy I2S slave ! Can it do USB playback ? T3.2 or T4.0 ?
-
FreeDSP-AIO flaws ✅
- speaker mute before shutdown...
- it has a startup unmute circuit but no shutdown...
- One more7414 gate and 2 diodes and 2 resistors... ... voltage divider at the schmitt input set to trigger when Vin goes below 8V or so !? then OR that output via 2 diodes into the spk_sleep. Adjust: turn pot from full (cw) towards 0 (ccw) until the mute LED goes off.
- tested ✅
- Not much capacitance at Vin, more caps ! Could delay the shutdown ! More time to mute ! ✅
- speaker mute before shutdown...

Questions
How big is the VFD Power PCB?
It measures 83.5 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VFD Power use?
24 parts, built around the XL6009, ZXBM5210-S, 74132DC and DR125. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the VFD Power KiCad files?
From the mariosgit/VFD repository on GitHub, at the commit this page was made from: the board is PCB-KiCad/VFD-Power.kicad_pcb and its schematic PCB-KiCad/GP1294-Teens4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VFD Power design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
