This switching regulator board is a cool-running, inexpensive drop-in replacement for TO-220 linear regulators such as 7805 (5V) or LM1117/LM3940/etc. (3.3V). You can change between these voltages by selecting different variants of the regulator IC. Bill of Materials and more info at http://tim.cexx.org/?p=1471

BOM

1.1 Changelog:

• Added indicators for the chips and header to make the pcb easier to assemble
• Added indicator for LED positioning
• Reduced pcb height by 0.3mm
• Fixed positioning of cartridge reader guide holes
• Renamed IC1 and IC3 to make more sense

1.2 Changelog:

• Reduced pcb height by 1.4mm
• Relocated components to fit within the new size
• Modified footprint for cart reader
• Replaced the crystal (ECS-60-32-5PXDN-TR) with FQ1045A-6.000 to as this component is only 1.7mm tall instead of 4.3mm

1.3 Changelog:

• Fixed incorrect crystal footprint

1.4 Changelog:

• Fixed incorrect wiring to crystal

1.5 Changelog:

• Reduced board from 4 layers to 2 layers
• Reduced board cost from 16.10 USD to 7.35 USD
• Reduced board height by 1.7mm
• Removed ISP header, the board can now be flashed using a cartridge
• Removed C2, C3, LED2, LED3, R2 and R3 to reduce cost and size
• Reduced the pad size for the cartridge header, the pins will need to be cut down.

1.6 Changelog:

• Reduced board cost from 7.35 USD to 7.25 USD
• Reduced board height by 0.2mm
• Reduced board width by 0.3mm
• Replaced the FT232RL with a smaller and slightly cheaper FT232RQ
• Replaced the micro usb port with a USB C port

Quick and dirty IV-6 VFD tube breakout board.

Order as 0.8 mm 2 oz/in²

Should be good to about 12 A continous for a temperature rise less than 40 K (IPC-2221, 6 A, 2 oz/in,² internal layers)
