Custom PCB schematic and layout help

Using Arduino Project Guidance
1

Hi,

I am in the process of making a custom PCB based on the Arduino Uno and would like to get some feedback on my design.

This is for a data logger project that I am currently working on.

The goal is to monitor some signals on my vehicle, which will be isolated using some buffer ICs. The data will get parsed and sent to my bluetooth module through the atmega chip. The bluetooth module uses 3.3V logic, which is converted using a logic level converter based on the BSS138 transistor.

I am planning on using the ISP header port to program the ATMEGA328P using the Arduino IDE with a USBtinyISP programmer I am getting off of eBay [unless someone can tell me of something else better to use to upload my Arduino sketch].

Why is it based off of the Arduino and not based on it? Did you want to distance yourself from it? :slight_smile:

Just for you, I'll be basing my design on the Arduino instead of off the Arduino.

That being said, does my design look like it'll work from a hardware perspective?

Well, having not really much of a clue of what you're trying to do or the components... hard to say. Why not build yourself the complete schematic on a protoboard first? Makes it much easier to do some testing before you have it made on PCB, then at least you know that part is sound.

Sometmes this is a good idea, sometimes not. Stuff like RF and switchmode psus can't really be 'lashed up' as a prototypr.

Can you post the schematic with a white background, it should be heaps easier for everyone to read.
