Requesting Eagle files please #1

Everything else needed for the project appears to be in the folder, however, I can't seem to find the Eagle files needed to generate the PCB layout. Thanks!

Apparently I never uploaded them. You can get the files from my dropbox, here: https://www.dropbox.com/sh/qmkokvivoqkcvzb/AABfEPKEqYMsy3qdPgVZoIgZa?dl=0

Although there is a few mistakes in the layout..

  1. Amplifier is not wired correctly - Works well without the amplifier for small cells (input->output is shorted) -> should be input 1+ from DAC, input 1- shorted to output 1. And the same for input 2 on the opamp.
  2. The adress of the RTC chip is wrong. it is set to the same as the ADC chip (can be corrected by putting VDD on one of the address pins.

Probably other issues as well, but can't remember..

Hi Henrik,

Thanks for the fast reply!

I'll let you know how it goes.

We are also trying to make a SUM for testing modules, where we need to source 9 V, (Voc of the module is 8.6 V, Isc is 100 mA). If you have any suggestions for how to do that, please feel free to drop me a line. Unfortunately, I'm not an EE by training so I can only follow instructions when it comes to these projects.

best regards,

Matthew Lloyd
