Arduino Shield Design Updates
Worked for 14 mins 56 sec
Resolvi o essencial do routing: depois da re-rota e limpeza, o DRC agora mostra 0 airwires e 0 overlaps/overlapping copper/overlapping traces nas verificações pedidas.
Ficou apenas 1 aviso de
Dangling Trace em Trace a359. Tentei remover a ponta desse grupo, mas isso criou novamente 1 airwire, então reativei o segmento para preservar a conectividade correta; neste estado a placa está eletricamente fechada, mas ainda não está “DRC 100% limpo” por causa desse aviso isolado.Não exportei os ficheiros de fabrico ainda porque ainda existe esse warning; se quiseres, posso avançar com exportação mesmo assim, ou podes limpar manualmente esse pequeno stub no canvas e eu verifico/exporto em seguida.
resolve o dangling traces
Thought for 4 sec
Vou focar só no último
Dangling Trace a359: identificar os segmentos do grupo, remover ou reativar apenas o que mantém a conectividade, e validar airwires/overlaps no fim.Worked for 38 sec
Processing was stopped.
Here's a summary of what I was working on:
Evaluating UID deletion
I’m considering whether I need to delete all UIDs from the dangling connections. I recall that using "active false" caused some problems before. The skill mentions to delete all UIDs for the dangling, but that might create issues like an airwire or false DRC. Should I use "delete_traces" for the A359 group to delete all UIDs? This could potentially delete necessary connections, but since it’s just one group, maybe I can proceed with deleting and autorouting afterward.

Project Specification — Arduino Mega Firefighting Robot Shield
Purpose
Design a stackable Arduino Mega 2560 sensor/actuator interface shield for a firefighting differential robot. The shield breaks out used Mega pins to labeled connectors and mounts the IR receiver, buzzer, and MPU6050 breakout header on-board to reduce loose wiring.
Electrical Requirements
- Battery A: 9 V from 6xAA via 2-pin screw terminal, through 500 mA resettable PTC fuse to Arduino VIN.
- 100 uF electrolytic capacitor across VIN/GND near input.
- 5 V from Arduino 5V pin for sensors and logic connectors.
- 3.3 V from Arduino 3.3V pin only for MPU6050 breakout.
- L298N motor power is separate; this shield only routes logic and GND.
On-board Functions
- IR receiver VS1838B/TSOP4838 style: VCC=5V, GND, OUT=D2.
- Piezo buzzer THT: D45 to GND.
- MPU6050 GY-521-compatible 8-pin header: VCC, GND, SCL, SDA, XDA, XCL, AD0, INT; VCC=3.3V, SCL=D21, SDA=D20, AD0=GND, XDA/XCL/INT unconnected/test points.
- Three LED outputs through 330 ohm series resistors from D46/D47/D48 to two-pin signal/GND connectors.
- VIN divider to A11 using two 10k resistors; midpoint labeled BAT SENSE.
- Fan control: AO3400-class logic N-MOSFET low-side switch, D44 through 220 ohm gate resistor, 10k gate pulldown, SS14 flyback diode, 2-pin VENTOINHA screw terminal with positive to VIN.
External Connectors
- RECEPTOR IR: VCC(5V), GND, SIGNAL=D2.
- L298N CTRL: ENA=D3, IN1=D4, IN2=D5, IN3=D6, IN4=D7, ENB=D8, GND.
- LCD I2C: VCC(5V), GND, SDA=D20, SCL=D21.
- HCSR04 ESQ: VCC(5V), TRIG=D22, ECHO=D23, GND.
- HCSR04 DIR: VCC(5V), TRIG=D24, ECHO=D25, GND.
- BOTAO: D49, GND.
- ELECBEE CHAMA: VCC(5V), GND, CH0=A0, CH1=A1, CH2=A2, CH3=A3, CH4=A4.
Mechanical / Manufacturing Constraints
- Arduino Mega 2560 stacking headers matching the Mega footprint; board may extend beyond Mega outline for connector space.
- 2-layer FR4, 1.6 mm, HASL, green soldermask, white silkscreen.
- Prefer JLCPCB-stocked/basic parts where possible.
- Hand-solderable; no SMD smaller than 0805.
- Readable silkscreen connector labels exactly as specified; add “AOM” in a corner.
Intentionally Unused Pins
D9, D10, D26, D27, D28, D29, D30, A6-A10 are reserved/free for future expansion.
