Launching Micro:Bits Auto Uploader

To download the codes to the Micro:Bits, the software will generate a HEX file. The HEX file need to be transferred to the Micro:Bits device (copy-paste) like transferring a file to a thumbdrive.

To avoid the hassle, we can use the Micro:Bits Auto Uploader. You can download the program from the link below.

Open the Auto Uploader and then leave it running. It will do its job by itself.

Running on Battery

Micro:Bit can get its power supply from the USB cable and also the Battery port.

We will disconnect the USB cable from the Micro:Bit and connect the Battery pack to the battery port.

The codes transferred to the Micro:Bit will stay with it even if the USB cable is disconnected.

Once the battery is connected, the Micro:Bits will restart and then you can see the same code running on it.
