The Treedix is a bench-style DC-DC module that steps voltage up or down automatically, so one board covers both boost and buck jobs. It takes 7-32V in and puts out 0.5-32V at up to 4A and 50W with added cooling, with constant-current and constant-voltage modes and a built-in voltmeter and ammeter. The 0.01V and 0.001A readouts suit bench testing, battery charging and small solar or LED projects. Against fixed boost or buck boards it is more flexible; against lab power supplies it is far smaller and cheaper but has no mains input and needs a heatsink for full output.

This is a DC-DC automatic boost/buck converter module with constant current and constant voltage (CC/CV) control. It works as an adjustable regulated power supply and includes a built-in voltmeter and ammeter.
The module accepts 7V-32V input and outputs 0.5V-32V. It can deliver up to 4A and 50W with enhanced heat dissipation. The display reads voltage to 0.01V and current to 0.001A.
