BOM

U1: SN74AHCT00DR

R1: 10K 0603

R2: 330 0603

This board is used in place of a tabbed CR2025 on Game Boy games, the benefit of using this over a tabbed battery is that Chinese tabbed CR cells suck, and Panasonic Tabbed cells are expensive, with these you can use any CR2025 cell you want.

Should be compatible with most if not all GB/GBC games that use Tabbed CR2025 cells

Retainer Part Number: BK-6219-TR

Boards should be ordered with the flex option

Notes

Bend the tabs on the coin cell retainer so they put less pressure on the board.

Changelog

Revision 2

• Added planes to the top and bottom to stiffen up the board (ironic i know)
