Ultimate RTC module replacement for Dallas DS1287, Benchmarq BQ3287, BQ4287 etc.
About this video
Dead real-time clock modules such as the Dallas DS1287 are the target of the nwX287, a drop-in replacement the maker presents for that chip and for the BQ3287, BQ4287 and ODN12C887.
Good to know: Old Dallas-style modules have a lithium cell sealed inside: never heat, short or charge one. Any desoldering brings burns, fumes and lead.
Why watch it
Several chip families, among them Dallas and Benchmarq parts, are named by the maker as targets for a replacement design. The GitHub project is linked, so the design can be read alongside the video.
