Tôi có thể thay bằng mạch XL6009 2310E được không

[@ajaytainwala]

Bro this would be costly know you can buy multimeter in 150 bucks

[@stephaneboudin4830]

why 1k resistor ?

[@geek4tec605]

Tu reduce the current

[@stephaneboudin4830]

@@geek4tec605 see yes ! but 47V / 1k = 47mA ! it's too big !
for zener, test @ 5mA, led ok @5mA
