Xiao MG24 vs. Xiao Nrf52840... Battle of the Senses' 🥊

Hi Agah_EVCAN,
There is a report comparing nRF52840 and MG24 in terms of sleep and advertise current. Please refer to.

Light / Deep Sleep Current Comparison of XIAO_MG24 and XIAO_nRF52840

I compared the sleep current between the newly released MG24 and the nRF52840, which is well known for its low current consumption. I hope this will be helpful. Measurements were taken by applying 3.8V to the battery pad on the back of the device and using ppk2. Sleep current is very sensitive to temperature, so I kept the room temperature at 25°C as much as possible. The BSP was “Seeed nRF52 Borads 1.1.8” and “Silicon Labs 2.2.0”, and I only did as much as I could with ArduinoIDE. The result…

BLE Advertising Current Comparison, ESP32C3,C6,S3, MG24, nRF52840

My project interest is to send sensor data from Peripheral to Central with low current consumption BLE. If the transmission is infrequent, a large current consumption reduction can be achieved by sending the data on the Advertise packet as ManufactureSpecificData without connection. ‘System_ON_Sleep of XIAO BLE - #31 by msfujino’ It is also important that the value of the sleep current be as small as possible since most of the time the device is in sleep mode, and that the current consumption …
