I thought I'd start a different type of "latest pickup" thread around cheap electronics modules / boards and other parts. I have seen a few helpful youtube channels cover this type of stuff, so I thought a thread on the subject matter could be another way to look at them. Feel free to contribute your own finds here. Most stuff is from either Aliexpress, eBay, or Banggood, with lead-times of a few weeks.
I'll start with this small this DC-DC converter. It is a kit you basically assemble some laser cut clear acrylic pieces around the board. It's a cute design as far as these boards go. It has a very nice backlight LCD display, which shows voltage and current, but is a little gimmicky since it shows a battery symbol with bars in it, but they don't really do anything. No on/of switch is to be found, however, the voltage can be calibrated for better accuracy.
