About the IoT-Enabled-Sustainable-Greywater-Recycling-System- PCB

IoT-Enabled-Sustainable-Greywater-Recycling-System- is an open source ESP32 PCB design by asif-ali-100, published on GitHub under the MIT license. It is a board, with 35 components from 19 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the Voltage_regulator_12to5V. By type, the board carries 8 connectors, 5 modules, 5 transistors, 5 relays, 5 diodes and 5 resistors.

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

From the project

Layout is optimized for correctness and readability, not final PCB placement — rearrange/route as needed once it's open. Expect ERC warnings for the ESP32's unused pins (flash, EN, SENSORVP/VN`) — that's expected since this design doesn't use them.
