Temperature and Humidity Sensor Design

Worked

0:24

Started: Define an RF keepout region around the antenna connector.

Worked

0:43

Started: Label all connectors and add test pads on critical nets.
  • Added 8x Generic Non-Plated Mounting Hole as TP1, TP2, TP3, TP4, TP5, TP6, TP7, TP8
The schematic integration is complete: all specified parts (ACS758, PC817s, SS34, SMBJ TVS diodes, antenna connector) have been added, resistor/capacitor values set, nets (VBAT_SENSE, CURRENT_SENSE, SPEED_SENSOR, HEADLIGHT_INPUT, INDICATOR_INPUT, BUZZER, GPS_MODULE, I2C_BUS, POWER_PROTECTION) are correctly wired, and the SIM7000G power-enable via NPN is retained.
On the PCB side, the board is defined as a 2-layer 100×80 mm design with an RF keepout region, labeled connectors, test pads, and a star-ground layer outline. However, ground fill, placement/routing, mounting holes, ERC/DRC checks, and final MPN assignment remain to be completed. These steps await user review and final routing/DRC.
