Original JYETech DSO138 DIY Digital Oscilloscope Unassembled Kit SMD Soldered 13803K Version
Note: This version SMD is soldered, is much easier than 13804K version. This is an unassembled kit, customers should have some basic electronic activity and ability, because of different levels of ability, we can not guarantee that everyone can DIY success, but we are committed to do our best of after-sales service.
