In my case I have implemented it with resistors SMD to reduce the final size of the module, and do not rule out in the future to lighten it even more by changing the transistor by one SMD; also It is possible to do it with ceramic resistances more easily, and that's that I've done the following diagram with them so that everyone can develop it without the added problems of the micro-welding.
Katika kesi yangu mimi na kutekelezwa kwa resistors SMD kupunguza ukubwa wa mwisho wa Moduli, na utawala wa nje katika siku zijazo kwa uzito zaidi hata kwa kubadilisha na yaliwekwa kwenye mashine na mmoja SMD; pia Inawezekana kufanya hivyo na resistances kauri kwa urahisi zaidi, na hiyo ni kwamba Umefanya kosa mchoro ufuatao nao ili kila mtu wanaweza kuendeleza bila matatizo aliongeza ya micro-muunganiko.
