Free LIR2450 charger PCB's

Jay Kickliter

I just got some PCB's back from Gold Phoenix. The board is for charging single CR2450 cells. Since I take a whole lot from these forums, and contribute little, I thought I'd give some away. The first ten people to respond will get one.

Before requesting:
* North America only
* please respond in this thread, then send an email to jay@kickliter.com with your mailing address
* I'll try to mail them out tomorrow, but no guarantee

I ordered 90 boards. If there's still any interest I may consider selling some populated boards, along with bare PCB's.

It's a really simple design, but I'd only request one if you can solder SMT components. One IC, MCP73832, handles everything. The rest are just passives. Read the datasheet for choosing the programming resistor. It sets the constant current during the first phase of charging. Higher current makes charging faster, but reduce the number of charging cycles you'll get out of a cell. The schematic has part numbers for the non-commodity parts. You can find the actual cells several places, including Sparkfun.

Thanks for all the help over the last few years.

Hey, I'll take you up on one. I think I already have one of those batteries.

Thanks,

I would like one of these if they are still available.

VERY nice of you, Jay! I don't need one, but just wanted to give you props for "giving back". As you said, this is a very helpful and friendly forum, and it's gestures like yours which make it so. Well done sir!
