Subject: Finishing the PCB

Date: 7/1
I finally finished re-routing the PCB; it was one of my most challenging tasks, as I had to manage various signal lines (SPI, UART, USB) while prioritizing noise control and isolation to prevent interference with the traces.
The board is essentially a flight controller (FCB) featuring an IMU, magnetometer, barometer, MCU, and flash memory, along with external connectors for the ESC, radio, GPS, etc. It measures 45x50mm—compact compared to commercial double-sided flight controllers—and is a 4-layer board.
