Jack did a great review on the BattLab-One. You can find it here:
Just published a new video showing the battery life impact of Deep Sleep vs. Light Sleep modes for the ESP 32
The completed BattLab-One! Capable of capturing uAmps to 500 Milliamps current profiles. It enables you to determine battery life and do what-if analysis on your battery powered (IOT) projects.
Adding the BNC trigger input (shown at right) caused a complete redesign of the board. The BattLab-One can trigger from a 3 – 5 volt input on a rising edge. It will stop capturing current on the falling edge.
