Energy Harvesting Shields for WiFi Micro – Part 2

I finally received the components form element14 and in a couple of days i also soldered the ics and the passives etc and did some preliminary tests. I am delighted to tell you that the preliminary tests were a success. Over the next few weeks i will do some more extensive tests to check its performance in various situations and record the performance.

I had never soldered smd ics before (i did solder a few smd sensors, but they were really easy to solder) so when i started soldering the BQ25570 board i actually screwed up 3 of them. It was the 4th and the 5th boards that were successful. Gaining from the experience of soldering BQ25570 i was able to solder BQ25505 in the first go šŸ˜€ .

Here are the assembled pieces –

I am sorry to say that i forgot to mark the graphs for what measurements they were showing. I will do that when i post the more extensive results.
