Description
2 relays WIFI commutation
just 1 strap for single face PCB
This board can be powered through differents kind of powers :
from the H1 connect a LIPO battery (deepsleep available shunt GPIO16 to RST pins)
from the H1 connector DC 3V3 directly (shunt in&out AMS1117 pins and use 3V3 relays)
from the H1 connector DC input from 5V to 15V (adapt the relays' voltage)
using a AC/DC power converter HLK-PM01/HLK-PM03
R5 and R6 4K7 can be soldered when using I2C protocol
Connect IO0 to GND for flash
