ANGAZA ELIMU: common questions

What microcontroller does the ANGAZA ELIMU use?

The ANGAZA ELIMU is built around the RP2040TR7, from the RP2040/RP2350 family.

How big is the ANGAZA ELIMU PCB?

The ANGAZA ELIMU measures 131 × 78.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ANGAZA ELIMU?

207 components, from 88 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 ANGAZA ELIMU design files?

From the R-Mutura/ANGAZA_ELIMU_PCB 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 ANGAZA ELIMU design in my own project?

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

Can I test firmware for the ANGAZA ELIMU 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.
