Left: common questions

What microcontroller does the Left use?

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

How big is the Left PCB?

The Left measures 132.6 × 112.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Left?

95 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Left design files?

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

Can I use the Left design in my own project?

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

Can I test firmware for the Left 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.
