I tested actual charge current

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

In my previous log I calculated indoor battery charge current would be approximately 50uA. Now I have measured actual charge current. I used a multimeter with lux meter as a reference.

Indoor at 500 lux I measured 61 uA.

Indoor under a table, 150 lux, I measured 12 uA.

This means that TSEM is indeed able to power a very simple BLE or LoRa application.
