For sale are new made GW-1287-1 RTC/CMOS repair boards. This listing is for the repair board only, no RTC IC is included. These repair boards can be installed on a NOS DS1285 or can be used to repair an existing DS1287 module with a dead battery. When the battery dies, simply remove it and insert another CR1225 coin cell!

If you'd like to build your own module or rework an existing DS12887, see our other listings for DIY repair boards! We also have assembled GW-12887-1 RTC modules that are 100% drop-in replacements for the DS12887, pre-assembled and ready to go.

You will receive the item shown in the first picture -- a repair board and CR1225 lithium coin cell. Other pictures illustrate the paneling process and the finished GW-1287-1 module. Again, this listing is for the repair board only, no RTC IC is included.

This item uses a lithium cell and will be marked as such for mailing. This may increase delivery times in some cases, especially overseas.
