ESP\_EN ini nyambung ke pin apa dulu ? apa ada resistor pull up nya ?

@copilot ESP_EN ini nyambung ke pin apa dulu ? apa ada resistor pull up nya ?

copilot

Dalam desain referensi Anda, sinyal ESP_EN terhubung ke beberapa elemen berikut:

J1:Pin_2
Q1:D (Drain dari transistor)
RST:~1 dan ~3
C11:P1
R1:P1
U2:EN (Enable Pin dari ESP32-WROOM-32E)
C7:P1

Yang penting diperhatikan adalah terdapat resistor pull-up R1 dengan nilai resistansi 10kΩ yang terhubung ke jalur +3V3. Dengan adanya resistor pull-up ini, pin EN pada ESP32-WROOM-32E akan berada dalam kondisi high secara default, memungkinkan ESP32 untuk berfungsi normal selama power-up.
