Pre-delivery Update

Dear backer,

Here is some good news and some more delays to consider:

The shields are fabricated:

Considering the small number of boards, I made them myself. This was more difficult than expected because I switched to no-lead solder paste. This needs a higher temperature and it does not spread very well. Plus the fact that the PCB is 2 oz copper (for its heat dissipation capability) it was very difficult to heat properly.

Finally I could bake them

And we have a small batch ready

I upgraded the MCU to Atmega328p because Atmega168p was full over 90% and thus it might not allow any firmware upgrade.

Some delays to consider

I just received the split cables today, but I am still waiting for some more OLEDs to add to the kits so I will try to ship some orders next week but others will have to wait maybe 2 or 3 more weeks.

I will keep you informed.

PowMeter Shield Deluxe Kit

Everything you need to start monitoring AND displaying power consumption. You will receive one PowMeter Shield, one custom programming/monitoring USB cable, one Nano clone, and one 0.49" OLED I2C module.



I have been interested by electronics as a hobby for a couple of years and wanted to go as far as possible in the development of a finished product.
