Adafruit Feather RP2040 Prop-Maker: common questions
What microcontroller does the Adafruit Feather RP2040 Prop-Maker use?
The Adafruit Feather RP2040 Prop-Maker is built around the RP2040_QFN56, from the RP2040/RP2350 family.
How big is the Adafruit Feather RP2040 Prop-Maker PCB?
The Adafruit Feather RP2040 Prop-Maker measures 50.8 × 22.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Adafruit Feather RP2040 Prop-Maker?
160 components, from 127 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 Adafruit Feather RP2040 Prop-Maker design files?
From the dcuccia/digital-handbell 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 Adafruit Feather RP2040 Prop-Maker design in my own project?
Yes, under the terms of its MIT license, which dcuccia chose for the repository.
Can I test firmware for the Adafruit Feather RP2040 Prop-Maker 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.
