Auto-routing paused

Thought for a moment

Avancé bastante, pero se agotaron los créditos justo cuando iba a enrutar la nueva versión.
Estado actual del proyecto:
  • Convertí la arquitectura a una versión soldable a mano.
  • Reemplacé los bloques SMD difíciles por headers through-hole:
    • STM32 externo por headers J3–J6.
    • Sensores I2C por headers J7–J9.
    • Módulo de micrófono/MAX4466 por header J10.
    • ESP8266 externo por headers J11–J13.
    • RGB externo por header J14.
    • Motor externo por header J15.
  • Reemplacé componentes SMD posibles por through-hole:
    • Q1 → PN2222A TO-92.
    • D1 → 1N5819G axial.
    • U6 → LM1085T-3.3 TO-220.
    • SW1/SW2 → pulsadores through-hole.
  • Cambié resistencias a formato axial through-hole.
  • Cambié capacitores a disco/radial through-hole.
  • Ajusté el regulador LM1085 según datasheet:
    • C11 entrada → 10uF.
    • C12 salida → 22uF.
  • Agrandé la placa a 120 mm × 140 mm.
  • Recoloqué los componentes para soldadura manual, con headers en bordes y más separación.
Pendiente:
  • El enrutado quedó sin completar porque se agotaron los créditos.
  • La última revisión antes del enrutado mostraba airwires, lo cual es normal porque todavía falta rutear.
  • Falta ejecutar:
    1. Autoruteo/ruteo final.
    2. Revisión completa.
    3. Corrección de posibles errores restantes.
    4. Exportar Gerbers/BOM si quieres fabricar.
Importante: no descargues todavía para fabricar. El esquemático ya está adaptado a soldadura manual, pero la PCB aún necesita el ruteo final y revisión limpia.

Project Specification — Wearable Industrial Safety Monitor
Requirements
  • 2-layer PCB, approximately 70 mm x 50 mm, rounded corners.
  • Bottom layer used primarily as a continuous GND plane.
  • Compact wearable industrial safety monitor.
  • MCU: STM32C011 microcontroller/module.
  • WiFi: ESP8266 module connected over UART.
  • Sensors: MPU6050 over I2C, BME280 over I2C, MAX4466 microphone analog output to MCU ADC.
  • Outputs: RGB LED with current-limiting resistors; vibration motor driven by 2N2222 NPN transistor and flyback diode.
  • Inputs: SOS pushbutton and reset pushbutton.
  • Power: single-cell LiPo input through JST connector, AP7361 3.3 V regulator, regulator input/output capacitors, IC decoupling capacitors.
  • I2C pull-ups: 4.7 kΩ to 3.3 V on SDA and SCL.
  • Layout: separate analog microphone area from digital/RF area, keep ESP8266 antenna clearance free, manufacturable routing.
Initial Architecture
VBAT from JST connector feeds AP7361-33 LDO. 3V3 powers STM32C011, ESP8266 module, MPU6050, BME280, MAX4466, and RGB LED channels. STM32C011 is the central controller; ESP8266 is a UART WiFi coprocessor. MPU6050 and BME280 share the I2C bus with one pull-up pair. MAX4466 analog output is routed to an STM32 ADC-capable pin. RGB LED channels and vibration motor driver are controlled by GPIO/PWM-capable outputs.
Assumptions
  • ESP8266 peak current requires a regulator/power path capable of at least 500 mA with adequate bulk capacitance; AP7361 variant should be selected/rated accordingly.
  • The ESP8266 module will be placed at a board edge with its PCB antenna facing outward and with copper/component keepout under/in front of the antenna.
  • STM32C011 pin assignment will use common GPIO names and be verified against the selected package/module pinout before manufacturing.
