Inwall relay esp32: common questions

What microcontroller does the Inwall relay esp32 use?

The Inwall relay esp32 is built around the ESP32-PICO-D4, from the RP2040/RP2350 family.

How big is the Inwall relay esp32 PCB?

The Inwall relay esp32 measures 32 × 10.3 mm, has 4 copper layers and is 0.98 mm thick.

How many components are on the Inwall relay esp32?

19 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Inwall relay esp32 design files?

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

Can I use the Inwall relay esp32 design in my own project?

Yes, under the terms of its GPL-3.0 license, which slaesh chose for the repository.

Can I test firmware for the Inwall relay esp32 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.
