Dose pin order from left to right at bottom side Reset , vcc (3v3), gnd , swim correctly?

Omg , I'm sorry for this
Reset , gnd , vcc, Swim . Hope stm8 not burn .
If it bad , I will send you file bin to load firmware . But you have to replace new chip st8

Still not able to connect it to ST Link,I think it was killed by me ~

I place a order for new MCU and hope I can get it at next week!
Would you please post the firmware here?
Thanks!

hi dc9 .Sorry for missing topic
you should power v for rx , then check volt 3,3v to sure , next is solder stm8
i send firmware stm8 rx sfhss . Good luck .

I replaced new MCU to receiver, but still can not connect to it via ST-Link , I think the board was broken already!
Thanks John!
