CR2032 Battery Holder Board

Bare Board – Ready for Assembly

Alternate Part: We also carry a fully assembled slim-line case with an integrated on/off switch. See our CR2032 Slim Holder with Switch.

This battery holder is by far the easiest way to add a single battery to a small design and includes a bonus power switch. This battery holder uses one Lithium CR2032 (20mm diameter, 3.2mm thick) sized coin cell resulting in 3v DC output. Lithium coin cells are not rechargeable, but they are inexpensive and very easy to find.

Perfect for soldering into a circuit or inserting the leads into a breadboard. Ideal for electronics projects, restorations, robotic designs, cosplay costume, or driving LEDs.

This small board measures only 38mm x 30mm (1.5" x 1.2").

This is the bare PC board only. You must supply all the parts. If you would prefer to purchase a complete kit of parts or an assembled product, see the CR2032 Battery Box.

Parts Needed for Assembly

• CR2032 Coin Cell Battery Holder
• CR2032 Coin Cell Battery
• Mini Switch (compatible with Top, Side or Push Button Switch options)
• Pair of Connection Wires

Battery Box Built-In Options

Switchless Operation Jumper

There may be installation requirements where you would prefer not to install a switch on board. If this option is desired, there are a pair of solder pads on the back of the board. Simply solder-bridge the two pads and this will eliminate the need for a switch and will result in unit always operating in the on mode.

Onboard LED Indicator

For applications where you would like to run an LED with the controller, there is a set of pads on the board specifically for this. The mounting position is labeled LED. The LED is powered when either the switches are turned on or if there is a jumper placed across the Switchless Operation jumper.
