Keebee: common questions
What microcontroller does the Keebee use?
The Keebee is built around the 497-1242-6, from the STM32 family.
How big is the Keebee PCB?
The Keebee measures 275 × 103 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Keebee?
152 components, from 21 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 Keebee design files?
From the blakesmith/embedded repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Keebee design in my own project?
The repository has no license, so all rights stay with blakesmith. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Keebee without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
