Hardware non commercial Accesoiry Homekit

Hi all,

I would like to learn how to make an accessory for a non commercial. I find many documents about the software or the API. However, at this step, I would like to know the way to start with hardware. Is there a BLE or IP module to create a prototype? Can we buy OEM product which are comply with Homekit as a developper or non commercial use?

Best regards,
