Schematic Design and Parts Placement
@help How do I draw a 5 V power bus and a 3.3 V power bus on my schematic?
@library Place ESP32-S3-WROOM as U1, AMS1117-3.3 LDO as U4, and LAN8720 RMII PHY as U3 on a 60 × 60 mm canvas.
@library Add RP2040 QFN-56 footprint as U2, including its 12 MHz crystal and caps.
@library Add OV5642 24-pin FFC connector as J1, VL53L4CD LGA-10 as U5, MPU6050 LGA-24 as U6.
Place nine JST-SM 3-pin connectors P1–P9 for FSR inputs, nine JST-SM 3-pin connectors P10–P18 for servo PWM.
Connect U1 VCC to the 3.3 V bus, P10–P18 V+ to the 5 V bus.
Connect U1 RMII pins to U3 RMII pins; connect U1 SPI0 to J1 SPI nets (MOSI, MISO, SCK, CS, VSYNC, HSYNC, PCLK, XCLK).
Connect U1 I2C pins to U5 and U6 SDA/SCL, add 10 kΩ pull-ups.
Connect U1 ⟷ U2 via SPI (MOSI, MISO, SCK, CS) for sensor/actuator data.
@help How do I add 0.1 µF decoupling capacitors on all VDD pins and a 10 µF bulk cap at the LDO input?

Here are the parts I’ll add to your schematic. Let me know if you’d like any changes:
- ESP32-S3-WROOM-1-N16R8 as U1
- RP2040 QFN-56 with 12 MHz crystal & load caps as U2
- LAN8720 RMII PHY as U3
- AMS1117-3.3 as U4
- OV5642 24-pin FFC Connector as J1
- VL53L4CD as U5
- MPU-9150 QFN-24 as U6
- SM03B-SRSS-TB(LF)(SN) as P1–P9 and P10–P18
Shall I apply these changes?
