Hi ESP_Minatel,
i did use the 1st PKK. It seems like the maximum current I measured currently is 80mA, I cannot still find the way to drive the esp32-Tinypico.

我试图用nRF52 power profiler测量board Tinypico的功耗，但似乎nRF52无法驱动Tinypico来传数据。所以我使用了一个乐鑫板子来检查nRF52是否有问题，但这个乐鑫的板子可以正常工作。想请问下潜在的问题可是什么?
感谢各位大佬

It is that I try to measure the power consumption of board Tinypico with nRF52 power profiler, but it seems like that the nRF52 cannot drive the Tinypico, which means I cannot power the board to work to transfer data. So I used a board of Espressif to check whether the nRF52 gets a problem and the E...
