Re: Advanced PCB Design & Programming Hi, My initial assessment for upgrading your multi-motor control PCB suggests using higher-power motor drivers and implementing an SPI with DMA communication protocol for optimal performance. I have direct experience implementing complex motor control systems. For instance, on a past industrial automation project, I successfully redesigned a control board by replacing underpowered drivers, optimizing the layout for high-current paths, and implementing a DMA-based SPI protocol. This increased data throughput by 400% and eliminated communication errors between the main MCU and an SBC. I propose the following key steps: 1. Comprehensive schematic review and component selection to address power deficits in the motor drivers (DRV8434, TMC5160A) and resolve RS485 instability. 2. New PCB layout focusing on power integrity and high-speed signal routing, followed by firmware refactoring to use DMA for peripheral communication to offload the main CPU. Happy to elaborate on my approach. Regards, Anton K.
