WORKED ON SCHEM PLACE ALL THE COMPONENTS THEN ROUTED PCB SOLVED ALL THE DRC ERRORS AND ALL AND COMPLETED THE PROJECT

Change all the smd components with through hole so it would be easy to assemble also routed the pcb place all the components and solved all the drc and completed the pcb

Today’s session focused on building out the core schematic for the Apex-1 board in EasyEDA. The following functional blocks were completed:

1. Microcontroller Selection & Placement

Selected the main MCU for the Apex-1 design.
Placed it centrally on the schematic as the core component all other sections connect to.
Pin headers on both sides are laid out for the various peripheral connections (power, GPIO, control lines).

1. Decoupling Network

Added a decoupling capacitor block near the MCU.
Two capacitor pairs placed to filter noise on the MCU’s power rails and maintain stable operation.

1. Switches Added three push-button switches (labeled BTN1, BTN2, BTN3).
   Each switch is wired as a user input line, pulled to ground/reference as needed.

2. Micro-USB Section

Added a Micro-USB connector for power input and/or data lines.
Wired the associated support components (pull resistors/connections) for the USB interface.

1. LEDs

Added a small LED bank (2 LEDs) under the “LED’s” block —likely for status indication (power/activity)
Added a second, larger LED bank labeled “LED(P)” with 5 LEDs, each with its own current-limiting resistor likely for a different purpose (e.g., pattern/output indicators).

1. Reset Circuit

Built the reset circuit block, including a transistor and reset button, feeding into the MCU’s reset pin.

1. Boot Pins

Added a Boot Pins header/jumper block to allow selection of the MCU’s boot mode (e.g., normal boot vs. bootloader/programming mode).

1. Debug Pins

Added a debug header for programming/debugging access to the MCU.

1. Crystals / Oscillator Circuits

Added two crystal oscillator circuits:

One labeled DIN/DOUT
One labeled DI2N/DO2N (secondary oscillator, possibly for RTC or a second clock domain)

Each includes the crystal and its associated loading capacitors.

Current Status:
All major functional blocks of the schematic are now drafted: power/decoupling, user input (switches), connectivity (USB), visual output (LEDs), reset, boot configuration, debug access, and clock generation (crystals).

PCB Routing and Completion of the Final Project

Today, I have completed the final step in my PCB design project PCB routing and finalization.

First of all, I had to choose the PCB layer stack-up. At first, I wanted to use fewer layers; however, considering that the components were distributed across the whole board and the routing was getting too complicated, I decided to use an 8-layer PCB. The 6-layer PCB was not enough to route everything well. I made the required configuration of outer and inner layers in order to have enough space for routing and connections.

After the layer stack up configuration, I proceeded with PCB routing and connecting all the components. This step became one of the most crucial steps of the project since all the connections should be made according to the design rules and be correct.

When I routed and connected the components, I proceeded to the DRC and corrected all the errors that I received during the check.

After correcting the errors, I made the last adjustments to the PCB, adding graphics and visual elements.

Now the PCB design is complete.

Status: Project Completed

Status: Project Completed

In today’s session, I have been working on the layout of the PCB. I have added all components to their respective locations within the board ensuring that the placement aligns with the design logic of the entire layout and not just a random addition.

While doing so, I have made some adjustments in some of the design rules based on the placement of the components on the board.

In addition to component placement, I have been working on the proper arrangement of all components on the board – arranging similar components together and arranging signals in a logical manner while labeling/naming them in an organized manner.

Up Next

Tomorrow will be the day when I will route the connection of all components.

Good things are in the pipeline

Today’s Progress

After completing the B2-STEALTH-FC project, I continued with the rest of the schematic and PCB designs. Since this project has been ongoing for some time now, today was all about connecting the remaining sections and preparing the design for the PCB phase.

I finished connecting the rest of the connectors such as the UART, ESC, final connectors, among others. I also included the mounting holes and finished the GYRO sensor section as well as the supporting connectors.

Once the schematic was done, I proceeded to create the PCB. I imported the schematic onto the PCB and started laying out the components and connections. I defined the board outline and the major board sections such as the USB-C interface and other critical sections.

The main structure of the board is done and the PCB design looks more like the actual flight controller PCB.

Today I continued working on the flight controller schematic. I completed and organized the main sections including the 3.3V regulator, decoupling capacitors, boot switch, and pinout connections for the ESC, camera, VTX, receiver, and power.
The core concepts and schematic structure are now in place. I’ll continue building on this and later integrate the motor, ESC, sensors, and remaining flight-control components. Still working on the overall design and refining the connections.

Day 1. Flight Controller PCB Design

To day, I have been working on the B2-Stelth-FC design and got to the stage of completing the schematic modules.

In particular, today, I have worked on the filtered flight-controller power section with BEC 9V 2A and BEC 5V 2A, power filtering, and the corresponding connections to the flight-controller electronics. Moreover, the USB-C port, oscillator, flash, I2C pull-ups, VBAT detection, buzzer, status LEDs were added to the B2-Stealth-FC.

ESC and power pinout, and the mounting/connection areas were worked out. The main goal of today’s work was to finalize the flight controller’s main circuit diagram and make sure that the power and signal circuits are properly separated.

Thus, it can be concluded that today, I have made the B2-Stelth-FC design to the stage of the key hardware blocks’ creation, which will be followed by the layout design and actual PCB layouting and testing procedures.
