Seeking Schematic for ZK-S4 Boost Converter Module from Aliexpress

[finos]

Hi everyone,

I'm reaching out to see if anyone here has the schematic for the ZK-S4 boost converter module that I recently found on Aliexpress . This module claims it can boost an input voltage of 2V to 30V with power output up to 80W, which is quite impressive and would be very useful for a project I'm working on.

I've searched around but haven't been able to find any detailed documentation or schematics for this specific model. If anyone has the schematic or any detailed information on this module, I'd greatly appreciate it if you could share it with me .

Thanks in advance for any help!

It definitely can't generate 80W with a 2V input, if that's what you're hoping for. The description says this:

2. High power, the maximum input current can reach 15A, the output current is 4A; when 3.7V input, the output power can reach 45W, when 12V input, the output power can reach 80W

So that fuse on the input is probably rated for 15A. I doubt it even performs as well as the description claims anyways.

Your best option is to buy one for a few dollars and reverse engineer it yourself.
