Iprld: common questions

What microcontroller does the Iprld use?

The Iprld is built around the ESP32-S3, from the ESP32 family.

How big is the Iprld PCB?

The Iprld measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Iprld?

88 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Iprld design files?

From the ICRS/IPRL-Electronics-Hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Iprld design in my own project?

The repository has no license, so all rights stay with ICRS. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Iprld 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.
