Before you start using the ENv5, please read the following documents accordingly: - ENv5 Test Version User Manual - ENv5 Revision 1 User Manual

Troubleshooting - When you notice the esp32 is not responding to the RP2040, you can apply the pre-build firmware to test. - some descriptions about the behavior of the test are available here.

Env: common questions

What microcontroller does the Env use?

The Env is built around the RP2040, from the RP2040/RP2350 family.

How big is the Env PCB?

The Env measures 57.8 × 34 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Env?

181 components, from 60 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 Env design files?

From the es-ude/elasticai.hardware repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Env design in my own project?

Yes, under the terms of its MIT license, which es-ude chose for the repository.

Can I test firmware for the Env without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
