Adapter PCB to replace the Cuco Z0 Modules on Gosund Smart Plugs with ESP-M2 Modules

The PCB features a Solder Jumper on the back side to control the pin mapping.

\ I have not tested all parts using this order links, no guarantee that every linked component works. Aliexpress links are affiliate links, so i will get a small commission when you order using this link. This will help me with further projects. Thanks.*

Gosund-ESPMod: common questions

What microcontroller does the Gosund-ESPMod use?

The Gosund-ESPMod is built around the ESP-M2, from the ESP8266 family.

How big is the Gosund-ESPMod PCB?

The Gosund-ESPMod measures 18.8 × 20.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gosund-ESPMod?

10 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gosund-ESPMod design files?

From the c-klinger/Gosund-ESPMod repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Gosund-ESPMod design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Gosund-ESPMod without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
