ReglaValor
Potencia: GND, THERMALINK_3V3, Net 10.5 mm
Señales / GPIO por defecto0.25 mm
Estado actual
  • La regla Power_Nets quedó en 0.5 mm para las redes de alimentación.
  • La regla general de trazas quedó en 0.25 mm para el resto de señales.
Nota sobre airwires
Los airwires reflejan conectividad, no grosor de pista. Así que:
  • sí quedan actualizados con las conexiones nuevas
  • pero no cambian visualmente de ancho por estas reglas hasta que enrutes trazas reales
Si quieres, el siguiente paso útil es revisar el listado de nets y confirmar que:
  • Net 1 sigue siendo tu red de 5V
  • no hay ninguna red de potencia adicional que también deba ir a 0.5 mm

Scope
ThermaLink-32 is a compact ESP32-based control and sensing schematic for a JLCPCB 2-layer project. The design uses an ESP32 DevKitC V4 (38-pin) module as the main controller, an IR transmit stage driven from GPIO13 through a 2N2222 transistor, a DHT22 on GPIO14, an HC-SR501 PIR output on GPIO27, a VS1838B IR receiver on GPIO25, and two push buttons to ground on GPIO32 and GPIO33.

Requirements
  • Main controller is an ESP32 DevKitC V4, 38-pin version.
  • IR transmitter uses GPIO13, a 330 ohm base resistor, a 2N2222 transistor, one IR LED, and a 100 ohm series resistor tied to 5V or Vin.
  • DHT22 data line connects to GPIO14.
  • HC-SR501 output connects to GPIO27.
  • VS1838B output connects to GPIO25.
  • Two push buttons connect GPIO32 and GPIO33 to ground when pressed.
  • All design components should be labeled as ThermaLink-32 related in component properties.
