Received TSEM R2 PCBs. It's working!

A project log for Tiny Solar Energy Module (TSEM)

A 1 square inch PCB module with 2 tiny solar cells, a highly efficient Li-Ion charger and with 3.3V and 1.8V output

Today I have received TSEM R2 PCBs and a solder stencil from Elecrow.

I really like the white soldermask. I actually dont like the silkscreen lines that indicate component outline, I will remove those in a next revsion.  I've put all components except the solar cells in the solder paste and used a hot air gun to reflow. The solar cells I soldered using the soldering iron, because they asre sensitive to excessive heat. 

Then it was time for the first test and I measured that the 3.3V and the 1.8V outputs were working. 

I am happy
