Sparkfun Variable Load board, display not working

Hi Im new here.
I recently purchased the Sparkfun board & display. Im having an issue getting anything to display. The board’s power light is active but no display. Im wondering if its my soldering or these boards


Any comments would be welcome

Hi Giovani
A close up of your soldering may draw some comments. A bit hard to tell from these pix.

Hi Giovanni,

Looks like you’ve picked your parts correctly, but I agree with @Robert93820 in that your solder joints could do with a closer look.

Have you tried communicating with the board over serial as shown in the hookup guide?

Keen to see this working!

They’re actually pretty big images when you open them full size. Soldering definitely needs some work - there are some pins that lokk like they’re not connected, and others that definitely look like they didn’t get hot enough.

The difference between a beginner and a pro is lots of flux :wink:

Make sure you apply flux, and get nice clean contact.

Thanks for all your replys!
Appoligies for the brutal solders. Im a hack.
I was able to run it on my computer via Putty. All works well

Cheers
