About the Z2m partner PCB

Z2m partner is an open source ESP32 PCB design by smarthomefans, published on GitHub. It is a 2-layer board measuring 50 × 50 mm, with 50 components from 23 distinct parts.

Its main chip is the ESP-WROOM-02, from the ESP32 family. Other key parts include the CH340C, CD4052B, E18-MS1PA1-IPX, 74LVC1G66 and AMS1117-33. By type, the board carries 14 resistors, 12 capacitors, 8 diodes, 7 ICs, 3 switches and 2 transistors.

It belongs with the iot & wireless designs in this gallery.

Hardware module for iobroker.zigbee

This is hardware module for iobroker.zigbee and zigbee2mqtt or Zigbee to Tasmota. If you can speak Chinese and be interested with this project, please look at this post in ioBroker China BBS

- Use E18-MS1PA1-IPX zigbee module. 20dBm power can make sure zigbee net work signal is strong. - Add an ESP8266 module. Give you another option that can connect zigbee module though wifi-to-serial (I was using this project). If your machine running smarthome platform, such as ioBroker or homeassistant, is put in a hidden corner, for better signal coverage, you can put your zigbee module in some where…

Z2m partner: common questions

What microcontroller does the Z2m partner use?

The Z2m partner is built around the ESP-WROOM-02, from the ESP32 family.

How big is the Z2m partner PCB?

The Z2m partner measures 50 × 50 mm, has 2 copper layers and is 1.2 mm thick.

How many components are on the Z2m partner?

50 components, from 23 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Z2m partner design files?

From the smarthomefans/z2m_partner repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Z2m partner design in my own project?

The repository has no license, so all rights stay with smarthomefans. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Z2m partner without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
