The BB-Prince is a small multi-purpose utility for your solderless breadboard. When you build something with a microcontroller (like an AVR or PIC) on a breadboard you usually need to wire up a reset button, some generic indicator leds, a power-on led and maybe a input button.
All of those things are already on this small (2.5x1.5cm / 1x0.6”) PCB ready to just be inserted and used on your breadboard.
There are six pin for hooking it up to your circuits.
The bottom connector have pins for
The top connector have pins for
1. Led #1
3. Led #2
The Reset have a 22K pullup and is brought LOW when pressed. This is what the most common microcontrollers expect.
The button have a 22K pulldown and goes HIGH when pressed. This will make the logic in your firmware easier to write and understand. Press=High=1=True.
Led #1 & Led #2 is connected to GND via 330 ohm resistors and lights up when you set the pins high.
There are also a green power led that is lit whenever the power is on.
Please note that the colors and make of the LEDs might change between shipments.
I’ve had this built on a simple piece of veroboard and used it for a while when building things on my breadboards but I decided that it was time to make it look a bit nicer so I made some PCBs for it.
I sell this as a kit so you’ll have to solder it up yourself but it’s very easy to solder it and it shouldn't take more than 5-10 minutes even for someone that's inexperienced in soldering.
As usual I don’t believe in high shipping costs so this is sent worldwide without tracking for less than a dollar.
