so i have shared the it’s schematic and board design with the eevblog.com community and they said “that this module will not work and the relay contacts and board tracks can’t handle high current” I improved and made the board anyway and tested it with inductive and resistive loads and it works without a problem huh
yup that’s true, i usually do my work with 5VDC , but i will switch to a Darlington transistor if i need to work with 3.3VDC in the future, thank you for the advise. 👍
