This is my first PCB, can someone check my schematic?

I'm worried if I've missed any components. Can anyone please verify if everything is alright?

I feel like I'm missing something with the microcontroller connection

what are the steps to program it?

potatoMan , 10-28-2025, 02:25 PM

for flashing? I am planning the firmware using UART peripheral that I made using the 4 header pins

did you think about the whole procedure of flashing? usually TX/RX are not the only signals needed

I think you would want a higher resistor for the (external) LED.
Where are your decoupling capacitors for the MCU?
