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.

Generic Capacitor
A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors.
