About this item
- The INA260 has a precision current-sense resistor built in, so it measures voltage, current and power directly.
- The ESP32-C3 adds them up into energy used, shows everything on an OLED and on a web page: ideal for checking a solar panel, a battery pack or how much your robot really draws.
- The complete kit is the whole parts list as a single item: we collect every part, check it and ship the set together, so nothing is missing when you sit down to build.
- Prefer to buy only some of the parts?
- The project page lists every part with its own price, and you can add just the ones you need.
