[WILL IT WORK?] Custom ATMEGA2560

[mdo131]

Hello. This is my first custom ATMEGA 2560 board.

I need some advice whether this board work properly or not.

AVR Newbie needs your help!



This board contains these functions.



1. Compatible with Arduino Mega 2560 Bootloader & Arduino IDE.

2. Uploads compiled file using Arduino IDE through USB TYPE C port.

3. Able to read & write files in Micro sd card

4. Able to play music file through PAM8403 & Micro sd card.

5. Speaker will be 5W

6. Able to read data from MPU-6050

7. Able to read Current Battery Voltage through Analog pin. ( PF0(ACD0) )

8. Work with standalone 60V battery. ( Actually, It wil be around 48V )



I've connected LEDs to uart ports to check data communication.



Thanks.

Hi,

I just had a quick view:

* I´d run all from 3.3V. Currently I don´t see the need for 5V.
* your XTAL circuit probably needs some capacitors.

Schematic is only one part of a reliably working circuit.
Also you need to have a suitable PCB layout with GND plane and EMI/EMC compliance.
