From the project
Reworked cheaper, maybe faster but less redundant drone controller.
This is a codebase that is woring to create a hardware+software solution for dron control and management in a relatively modular manner. This is a codebase that is woring to create a hardware+software solution for dron control and management in a relatively modular manner. This needs to be inherenly zero-trust, zero-fail and easy to analyse statically. The langauge of choice is C, with rust and python tooling accepted as well.Follow the 10 rules as set by nasa for code, the same should apply here due to the similar no-fail environment. Currently, the main control board has been designed and…

Esc rev b: common questions
What microcontroller does the Esc rev b use?
The Esc rev b is built around the STM32G431CBT6, from the STM32 family.
How big is the Esc rev b PCB?
The Esc rev b measures 173.8 × 282.9 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Esc rev b?
687 components, from 87 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 Esc rev b design files?
From the iamdarshg/drone-arm 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 Esc rev b design in my own project?
The repository has no license, so all rights stay with iamdarshg. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esc rev b 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.
