33NJU23: common questions

What microcontroller does the 33NJU23 use?

The 33NJU23 is built around the raspberrypi-pico-module, from the RP2040/RP2350 family.

How big is the 33NJU23 PCB?

The 33NJU23 measures 54 × 85.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 33NJU23?

71 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the 33NJU23 design files?

From the AlexEkb4ever/MURMULATOR_classical_scheme_ext_pair repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 33NJU23 design in my own project?

Yes, under the terms of its GPL-3.0 license, which AlexEkb4ever chose for the repository.

Can I test firmware for the 33NJU23 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.
