Breadboard Buddy Universal (V3)

Hey everyone. Got a new version of my BreadBoard Buddy out in the wild. I have only 1 left as they sold out quick. I’ll be making an order for new pcbs today. I’ll post a link also where to order later today. 1 lucky person is getting 2. They placed an order on tindie from me and I decided to give them the upgraded pcbs.

Here is info for it:

The newer version included 2 user LEDs and a universal layout for breadboards.

VIN Pin:
This pin connects to the regulator ONLY. It will NOT charge your battery. It will NOT touch USB Votlage. MAX VOLTAGE IS 6V on this pin.

LEDs:
L1 and L2 are both connected to ground with a 2K resistor. Simply supply a high voltage of about 2v-5v to turn them on.

User Button:
The Button can be Pulled High to 3.3v or 5V Using the solder jumper on bottom.

Lipo Charging/Power:
The battery charger can be set to either 100mA or 500mA charging current via a solder jumper on the bottom. When a battery is plugged in it will power the regulator on board. I used a BAT54C to share power with USB and VBAT so nothing blows up.

VCC Rails:
There are 2 rails. Left side and Right. Each rail can supply 3.3v or 5v to each side without affecting the other side. This is nice when you are working on a 5v / 3.3v system mixed.

LEDs are also using a higher resistor as they can be bright as heck. It’s nice to be able to see a LED on without blinding yourself. 🙂

Yes, for now the PCBs will be black.
