About the Breadboard VFD PSU PCB
Breadboard VFD PSU is an open source PCB design by ansemjo, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 51.7 × 33 mm, with 39 components from 36 distinct parts.
Other key parts include the AP2114H-3.3TRG1, LM2733YMF/NOPB, DS1338Z-33+ and 2021. By type, the board carries 10 connectors, 7 resistors, 6 test points, 6 capacitors, 3 ICs and 2 inductors.
It belongs with the displays & leds and dev boards & breakouts designs in this gallery.
From the project
hardware project for a clock around a russian ivl2-5/7 vfd and an esp32-wroom module
A vacuum-flourescent display (VFD) clock project based on Soviet NOS IVL2-7/5 / ИВЛ2-7/5 tubes. This has been my first somewhat complex hardware project when I got into electronics design in 2020 and grew to multiple iterations over the years.
vfddriver — updated display board, which can be used over I2C sandwich — the original clock design with two boards * other — links to initial research prototypes and various experiments
