There have been a lot of request for the bottom module lately, so it’s as bit of a search.
What do you think is wrong with the module? If it’s charging issues check the usb port and cable for dirt that may cause resistance.
Another issue is that the soldered joints of the usb to the module may be damaged, so if you like you attempt or ask someone else to effect a repair if that is the issue.
OK here’s a link to help repair if the problem is joint fatigue.
