About the ESP PCB

ESP is an open source ESP32 PCB design by bhaskar9980, published on GitHub under the MIT license. It is a 2-layer board measuring 57.1 × 62.7 mm, with 13 components from 12 distinct parts.

Its main chip is the ESP32_dev, from the ESP32 family. Other key parts include the AT24C512 and DS1307_RTC. By type, the board carries 6 connectors, 3 ICs, 2 capacitors and 2 resistors.

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

From the project

Guardian is an advanced, fully automated hydroponics system designed to optimize plant growth and maximize yield. Utilizing micro-controllers and pH fuzzy logic control, it ensures precise nutrient delivery, enables remote monitoring, and achieves remarkable water savings while increasing crop productivity.

There are two Modes for Controlling the Motors and lighting

We can Manually Control/ Automate the Threshold Values of Humidity and Temperature as per the crop

This Arduino compatible library is made to simplify the communication paradigm that happens between master ESP32 and slave Arduino Nano.

The slave arduino nano does the following: - controls 4 relays named as

ESP: common questions

What microcontroller does the ESP use?

The ESP is built around the ESP32_dev, from the ESP32 family.

How big is the ESP PCB?

The ESP measures 57.1 × 62.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP?

13 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP design files?

From the bhaskar9980/Guardian repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ESP design in my own project?

Yes, under the terms of its MIT license, which bhaskar9980 chose for the repository.

Can I test firmware for the ESP 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.
