this is a design of a flight controller for a rocket. there is a BMP280 to input data about altitude and a mpu6050 to input gyro data. the main controller is a ESP32-WROOM-32UE. the PYRO channels are there to eject parachutes. so can you guys tell me if i do something wrong. i'd highly appreciate it.

Careful- turning a model rocket into something with a guidance system is illegal in the USA, per FCC & Military, because it turns it from an experimental item into a missile. I kid you not.

Without knowing what LEDs, why are some resistors 15 ohm, another 56 ohm? Verify the current draw through the LEDs and then verify that you are not exceeding the I/O port current capacity (including overall current capacity per port or device).
In grid 5A, you have something tied to EN line, yet you have R1 with C1 in the EPS32 diagram.
In the Power "box", you show Vin, but it is not tied to anything for the input voltage (no connector source).

No one can tell if this will work or not, you are not showing all components like the UART. Your I2C (SDA, SCL) lines do not show any pull-ups. While there may be internal pull-ups in one or more devices, you have to verify they are enabled properly.
