Zymoscope

About the Zymoscope PCB

Zymoscope is an open source ESP32 PCB design by kodyvajjha, published on GitHub under the GPL-3.0 license. It is a board, with 1 components from 1 distinct parts.

Its main chip is the ESP32-WROOM-32E-N4, from the ESP32 family.

It belongs with the iot & wireless, sensors and displays & leds designs in this gallery.

From the project

ESP32-based fermentation monitor and temperature controller with a self-hosted FastAPI dashboard. Tracks temperature, estimates specific gravity via load cell weight loss, and controls heater/cooler relays via PID — all connected over MQTT.

An ESP32-based fermentation monitoring and control system with a real-time web dashboard.

Zymoscope monitors and controls fermentation environments using:

- Temperature sensing and PID control (DS18B20 probe + Kasa smart plug for heating/cooling) - Ambient climate logging (BME280 — temperature, humidity, pressure) - Local display on a 128x64 OLED for at-a-glance status - Wi-Fi telemetry via MQTT to a self-hosted FastAPI + SQLite web dashboard - NVS-persisted setpoint — the target temperature survives reboots; no dashboard needed to maintain control - Modular architecture — ESP32 sensor…

Zymoscope: common questions

What microcontroller does the Zymoscope use?

The Zymoscope is built around the ESP32-WROOM-32E-N4, from the ESP32 family.

How many components are on the Zymoscope?

1 components, from 1 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 Zymoscope design files?

From the kodyvajjha/zymoscope repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Zymoscope design in my own project?

Yes, under the terms of its GPL-3.0 license, which kodyvajjha chose for the repository.

Can I test firmware for the Zymoscope 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.
