Getting a board that works for everyone is probably not feasible. Because everyone has wildly varying requirements such as how they want to mount the sensor (or which external sensor they prefer), what voltage and current is needed, what communication interfaces are required, how much capacitance you want onboard, what connectors you prefer or just solder pads, what form factor it needs to be in, and most importantly cost. And some people want to be able to drive stepper motors as well with the same board. Because it is not possible to fulfil all these at the same time, that’s why there is no single “best“ board and it’s why people tend to go and make custom boards. Making a custom board is also fun and a good learning experience.
Taking my BLDC Driver V5 board as an example, it works well at driving the BLDC motors I have, and I would consider it to be a good flagship board. But other people might not like it because it uses RDSon current sensing (lowside) which requires more software work, and the only encoder that works well is a sin/cos encoder (either built into the motor or added with AS5115 magnetic encoder). It also has no mounting holes making mounting a bit more challenging, and it’s quite expensive to produce.
There’s also the SimpleFOC Bento board being developed which you should also take a look at, it seems to be good for many basic use cases.
For your board, my recommendations are:
Remove the split ground and the RC filter and the RFI filter.
Make the ground planes span the whole board.
Connect unused input pins of the second driver IC to GND or 3V3 so they don’t float.
Use wider traces for the gate signals, I suggest 0.2mm or more.
Add a few polymer electrolytic capacitors in the spare area.
In general it just needs more time to optimize the PCB routing.
Also if you’re planning to design a board for the community to use, it’s best to state your goals and target applications for the board, such as whether you want low cost, balanced, or high performance, voltage / current ratings, I/O capabilities, other special features etc.
