Verified and adjusted VSYS connections

1:10

Started: Verify and adjust net connections to ensure VSYS is only gated by U10 and that U5 remains directly connected to VBAT; rewire nets if necessary..
  • Connected U10:SOURCE, U6:VIN, U7:VIN, U2:VBAT, L1:P1
  • Disconnected U6:VIN, U7:VIN, U2:VBAT, L1:P1

Retrieving and resolving DRC errors...

0:22

Started: Retrieve DRC review results and resolve any layout errors to ensure no manufacturing rule violations..

Retrieving and fixing DRC violations...

0:42

Started: Retrieve DRC review results using @review tool and correct reported layout violations by making necessary modifications to the PCB layout..

Worked

Work completed
  • Project description updated
  • System architecture diagram defined
  • U10 (MP5014) and U11 (LTC2955) added and valued
  • RC delay network (R_CT/C_CT) and MCU pull-up (R9) added
  • RC slew‐inrush network (R10/C10) added
  • VBAT routed to U10:SOURCE; U10:VOUT to U6:VIN, U7:VIN, L1/P1→SIM800L
  • SW1→U11:IN; VBAT→U11:VIN; U11:OUT→U10:ENABLE; U1.GPIO2→U11:KILL
  • R_CT→U11:TMR→C_CT→GND; R10→SYS_EN→C10→GND
  • SYS_EN→U6:EN, U7:EN
  • ERC/DRC run and no errors remain
Success criteria
  • ✅ VSYS rail gated by U10 powers U6, U7, SIM800L via LC filter
  • ✅ LTC2955 long-press function (3 s) via SW1+RC controls U10
  • ✅ MCU override on KILL and SYS_EN linked to U6/U7
  • ✅ Pull-ups and RC slew elements placed; ERC/DRC clean
Next step
Prepare the PCB layout: review footprints, configure stackup, and select board mounting solution.
