que es EN FB

@copilot que es EN FB

En el contexto del regulador de voltaje MT3608, EN y FB son pines importantes que cumplen funciones específicas:
  • EN (Enable): Este pin se utiliza para habilitar o deshabilitar el regulador. Cuando se aplica un voltaje alto (generalmente el mismo voltaje que la fuente de alimentación) al pin EN, el regulador se activa. Cuando se aplica un voltaje bajo (o se deja flotando), el regulador se desactiva, lo que significa que no habrá salida de voltaje.
  • FB (Feedback): Este pin se utiliza para regular el voltaje de salida. El regulador ajusta su salida para mantener el voltaje en el pin FB a un valor de referencia interno predeterminado (por lo general, 1.23V). Esto se hace utilizando un divisor de voltaje externo conectado entre la salida del regulador y el pin FB.
¿Te gustaría saber cómo conectar estos pines en tu proyecto específicamente?

Claro, aquí te dejo las conexiones necesarias usando el regulador de voltaje MT3608MT3608 y otros componentes en tu proyecto. Estoy asumiendo que estás utilizando el MT3608 para convertir un voltaje de entrada a un voltaje más alto.
Conexiones para el MT3608
  1. Entrada de Voltaje (IN): Conecta el suministro de voltaje que deseas regular al pin IN de U2.
  2. Tierra (GND):
    • Conecta U2.2 (GND) a la tierra de tu circuito.
    • Conecta U2.2 (GND) a U1.10 (GND).
  3. Salida de Voltaje (OUT): El MT3608 no tiene un pin 'OUT' por sí mismo, pero la salida del voltage se obtiene del pin al cual se ha conectado el feedback (FB). Normalmente se conecta un divisor de voltage aquí, pero para simplificación, usaremos el pin FB.
  4. Feedback (FB):
    • Conecta un divisor de voltaje entre el pin FB de U2 y la salida ajustada (que también se puede conectar al pin VCC de otros componentes si necesitas un voltaje regulado que sea más alto que la entrada).
  5. Enable (EN):
    • Para habilitar el regulador, conecta U2.4 (EN) al voltaje de suministro de entrada. Si lo deseas, puedes conectar esto a un pin GPIO, como el D0 del Nodemcu12E_ESP8266Nodemcu-12E\_ESP8266 para controlarlo por software.
Conexiones Específicas del Proyecto
  1. Conectar U2.5 (IN) a la fuente de alimentación externa.
  2. Conectar U2.2 (GND) a U1.10 (GND).
  3. Conectar U2.3 (FB) al punto medio de un divisor de voltaje.
  4. Conectar U2.4 (EN) al voltaje de entrada o a un pin GPIO, por ejemplo, U1.30 (D0).
Ejemplo de Conexión para Habilitar el MT3608:
# Conexión del Pin EN al Pin D0 del ESP8266 para control por software:
Connect U2:4 to U1:30

# Conexión de la entrada de alimentación al MT3608:
Connect U2:5 to Supply Voltage

# Conexión de tierra del MT3608:
Connect U2:2 to U1:10

# Conexión de Feedback (FB) al divisor de voltaje adecuado:
Connect U2:3 to Voltage Divider
Conexión de Relevadores (KY-019):
  1. VCC (Pin 1) de los relevadores: Conecta K1.1, K2.1, K3.1, K4.1 a la salida regulada del U2.
  2. Signal (Pin 2) de los relevadores: Conecta K1.2, K2.2, K3.2, K4.2 a los pines GPIO del ESP8266 que prefieras usar para control.
  3. GND (Pin 3) de los relevadores: Conecta K1.3, K2.3, K3.3, K4.3 a la tierra de tu circuito.
Espero que esto te ayude a avanzar con tu proyecto. Si necesitas alguna aclaración adicional, ¡déjame saber!

@copilot list all ICs and the decoupling capacitors attached to each. Ensure to include all ICs present in the design, including digital ICs, power converters, LDOs, etc. For every IC, clearly state:
  • What power net the decoupling capacitors are attached to. What is the stated voltage of that net.
  • The voltage rating and value of the attached decoupling capacitors.
  • Signal with the expression “[WARNING]” if any of the following conditions are met: no decoupling capacitors are attached; the voltage of the power net is higher than the voltage rating of the capacitor; No voltage range was stated for the capacitor. Give a separate “[WARNING]” for each condition. Signal with the expression “[OK]” if none of those conditions are met
  • Express the result in a markdown-formatted table

From the information provided, there are two ICs listed as follows: Nodemcu-12E ESP8266 and MT3608. Your project does not provide explicit details on decoupling capacitors for these ICs. For comprehensive designs, it is standard practice to use decoupling capacitors to smooth the supply voltage and filter noise.
Below is a markdown-formatted table listing each IC, the power net they are attached to, if any decoupling capacitors are defined (none are in this case), and appropriate warnings:

Table


ICPower NetVoltageDecoupling CapacitorsVoltage RatingCapacitor ValueStatus
Nodemcu-12E ESP8266Net 23.3VNoneN/AN/A[WARNING]: No decoupling capacitor attached
MT3608Net 23.3VNoneN/AN/A[WARNING]: No decoupling capacitor attached
For proper decoupling:
  • Typically, for the Nodemcu-12E ESP8266, a 100nF and a 10µF capacitor both rated at least 6.3V should be used between VDD and GND.
  • For the MT3608, refer to the datasheet, which suggests using 22µF ceramic capacitors for input and output filtering3e083f80c39352b1a1d361d93669d6103e083f80-c393-52b1-a1d3-61d93669d610. Ensure these are rated appropriately according to the input and output voltages.
Would you like to proceed by adding these decoupling capacitors to the design?
