Other key parts include the TPS561201DDCR. By type, the board carries 7 capacitors, 4 diodes, 3 resistors, 1 IC, 1 connector and 1 fuse.
It belongs with the power & battery designs in this gallery.
From the project
Various printed circuit board projects
This is a simple PCB to test creating several voltages that are used on the Dishy1Pi PCB. Once this cirction is tested as working, the relevant schematic parts will be moved over to the DishyPi1 schematic. The voltages needed are: - 12V to power each of the 2 encoders. This voltage is supplied from an external power supply and protected by a PTC fuse on the Dishy1Pi PCB. Also reverse polatiry protected. - 5V to power the logic circuity on the Dishy1Pi PCB. This voltage is generated on this power supply PCB from the 12-24V input voltage using a buck converter.
