Microclimate Instrument for Real-time Remote Applications

⚠️ This is a research project. Limited testing has been performed and reliability of data storage/sensor readout is not guaranteed. Use with caution. ⚠️

The radiation is 3D printed and designed using OpenSCAD. All design files can eb found in 3dprinting`. They can be printed using an extrusion printer, with minimal post-processign (no supports).

Pcb gateway: common questions

What microcontroller does the Pcb gateway use?

The Pcb gateway is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Pcb gateway?

The Pcb gateway measures 76 × 92.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb gateway?

80 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pcb gateway design files?

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

Can I use the Pcb gateway design in my own project?

Yes, under the terms of its Apache-2.0 license, which mirra-org chose for the repository.

Can I test firmware for the Pcb gateway 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.
