The Heltec #ESP32 Lora v3 uses #TP4054 with 2K PROG resistor so it only supports 0.5A charge current which would give roughly 2W max. This is why I'm planning on connecting ESP32 to the 5V output of solar FP6276B and let it buck-convert to 3.3V via CE6260B33M.
I'm wondering if it would be possible to somehow measure the charge current and report that via the Lora node? Is #INA219 the only option?
