Hello - thank you for your excellent work! I just wanted to clarify the jumpers - I wasn't understanding if the jumpers needed to be soldered on the front or back of the PCB..

I have completed the whole build, but I soldered it on the back (instead of the battery/front side). After looking at some pictures of prior questions/issue posts, I noticed that there was a picture of the jumpers soldered on the front side.

Please forgive this newbie if this is a stupid question. I have never built one with jumpers like this before.
