Agriculture-VCU: common questions
What microcontroller does the Agriculture-VCU use?
The Agriculture-VCU is built around the STM32F446RET6, from the STM32 family.
How big is the Agriculture-VCU PCB?
The Agriculture-VCU measures 180 × 180 mm, has 4 copper layers and is 2 mm thick.
How many components are on the Agriculture-VCU?
192 components, from 51 distinct parts. The full bill of materials is listed on this page.
Where can I download the Agriculture-VCU design files?
From the laurapreidewe/Agriculture-VCU repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Agriculture-VCU design in my own project?
The repository has no license, so all rights stay with laurapreidewe. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Agriculture-VCU 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.
