“Bought this to build a custom humidity sensor for my AMS. It’s tiny, fits anywhere, and the battery charging is a lifesaver for making it wireless. Much better than using a bulky Arduino. If you’re into 3D printing and need a smart controller for your dry-box, this is the one to get. Fast delivery from Pi Hut too.”
“The Seeed XIAO nRF52840 is very good value and worked perfectly for my project using it for a bluetooth smart bike gear shifter.
Very fast delivery from The Pi Hut and great customer service.”
“My Seeed XIAO BLE nRF52840 has a batch fault. It will charge a 3.7v Lipo battery connected to the Bat + and - terminals, but it won't power the board when the USB power is removed.
There's a well-documented history of this issue, but the Pi Hut seem to be selling the defective units. There's a klunky work-around where you link the battery + to the USB 5V pin via a switch, and make sure to manually switch off the battery when connecting to usb power.
Me; I bought the board to be charged and powered from the 3.7v battery I bought; I'm bitterly disappointed, and won't be buying anything from the Pi Hut again.”
