About the IOT-Memento-Design PCB

IOT-Memento-Design is an open source ESP32 PCB design by AID-IOT, published on GitHub under the MIT license. It is a 2-layer board measuring 150 × 100 mm, with 9 components from 4 distinct parts.

Its main chip is the XIAO_ESP32C3, from the ESP32 family. Other key parts include the BMP280_Module. By type, the board carries 4 diodes, 3 resistors and 2 ICs.

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

IOT-Memento-Design: common questions

What microcontroller does the IOT-Memento-Design use?

The IOT-Memento-Design is built around the XIAO_ESP32C3, from the ESP32 family.

How big is the IOT-Memento-Design PCB?

The IOT-Memento-Design measures 150 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the IOT-Memento-Design?

9 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the IOT-Memento-Design design files?

From the AID-IOT/IOT-Memento-Design repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the IOT-Memento-Design design in my own project?

Yes, under the terms of its MIT license, which AID-IOT chose for the repository.

Can I test firmware for the IOT-Memento-Design 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.
