Capitulo136: common questions

What microcontroller does the Capitulo136 use?

The Capitulo136 is built around the 90147-1120, from the RP2040/RP2350 family.

How big is the Capitulo136 PCB?

The Capitulo136 measures 125 × 87 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Capitulo136?

23 components, from 11 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 Capitulo136 design files?

From the ComputadorasySensores/Capitulo136 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 Capitulo136 design in my own project?

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

Can I test firmware for the Capitulo136 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.
