XIAO NRF52840 10ma power usage when in sleep

[msfujino]

Please try the sketch for the nRF52840 available at the link below. At the very least, it should not produce any compilation errors. Please use BSP version 1.1.12.

Connect the brown lead of the PPK2 to the + terminal of the battery pad and the black lead to the – terminal of the battery pad, then apply 3.8V.

Is there a while(!Serial) statement in the sketch?

Why not start by testing whether the XIAO is working properly using Blink.ino?

Comparison of Sleep Current for XIAO nRF54L15, nRF52840, and MG24

I compared the sleep current of the newly released nRF54L15 with the nRF52840 and MG24, known for their low power consumption. I hope this proves useful. Measurements were taken using ppk2 while applying 3.8V to the battery pads on the device’s back. Since sleep current is highly sensitive to temperature, room temperature was maintained as close to 25°C as possible. For the BSP, I used “Seeed nRF52 Boards 1.1.10” for the nRF52840 and “Silicon Labs 3.0.0” for the MG24, working within the capabi…
