Below is a complete summary of the additional connection suggestions. You can use the Apply changes button to update your schematic accordingly.
Schematic Connection Summary:
Table
| Signal | From Component & Pin | To Component(s) & Pin(s) | Notes |
|---|---|---|---|
| Power – 3V3 | U1 3V3 (pin 1) | • [J1] Female header (ESP socket) • [J4] 15-pin female header (Pin 1) • MPU9250 U2 & U3 VCC pins | Supplies regulated 3.3V to the ESP, connector breakout and sensors |
| Ground (GND) | U1 GND (pin 2) | • [J1] Female header • [J4] 15-pin female header (Pin 2) • MPU9250 U2 & U3 GND pins • Ground component | Establish a common ground for the ESP, connectors, and sensors |
| ESC Drive Signal | U1 D15 (pin 3) | [J2] Male header (Signal cable to ESC) | Route the PWM output from the ESP to drive the ESC |
| I2C SDA | U1 D21 (pin 11) | • [J4] 15-pin female header (assign Pin 3) • MPU9250 U2 & U3 SDA pins | Creates the shared I2C data line (SDA) from the ESP to the sensors |
| I2C SCL | U1 D22 (pin 14) | • [J4] 15-pin female header (assign Pin 4) • MPU9250 U2 & U3 SCL pins | Creates the shared I2C clock line (SCL) from the ESP to the sensors |
Additional Notes:
- The [J1] female header serves as the ESP socket, so each corresponding ESP power and I/O signal should be routed to its matching pin.
- The [J2] male header is dedicated for the ESC drive signal (using ESP D15 in this example).
- The newly added 15-pin female header ([J4]) provides additional breakout connections. In this example, Pin 1 is routed to 3V3, Pin 2 to GND, Pin 3 to I2C SDA, and Pin 4 to I2C SCL. (Remaining pins on [J4] can be assigned as needed for other signals.)
- Both MPU9250 modules (designators U2 and U3) have their VCC and GND appropriately connected, and share the I2C bus (SDA/SCL) from the ESP.
These suggestions complete the interconnections between the ESP module, headers, ESC drive, and the MPU9250 sensors. Use the Apply changes button to update your schematic with these connections.

Below is a summary of the schematic change suggestion to remove all wiring connections and nets from your project. This will disconnect all currently connected signals between components.
Schematic Change Suggestion: Delete All Connections
- Action: Remove every net and wire in the schematic, including:
- All signal nets (e.g., I2C, PWM, power, ground, etc.)
- All portal connections in the project (e.g., [U2 SDA - U3 SDA], [U2 3.3V - U3 3.3V], [U2 GND - U3 GND], [U1 GND - J1 Pin_2], [U1 3V3 - J1 Pin_1], [U1 D15 - J2 Pin_1])
- Result: All existing interconnections between components will be deleted. The schematic will retain the individual components but with no connectivity between them.
You can now Apply changes to remove all the connections from your project's schematic.
