### Making your own UF2
To create your own UF2 DFU update image, simply use the [Python conversion script](https://github.com/Microsoft/uf2/blob/master/utils/uf2conv.py) on a .bin file or .hex file, specifying the family as **0xADA52840**. If using a .bin file with the conversion script you must specify application address with the -b switch, this address depend on the SoftDevice size/version e.g S140 v6 is 0x26000
To create your own UF2 DFU update image, simply use the [Python conversion script](https://github.com/Microsoft/uf2/blob/master/utils/uf2conv.py) on a .bin file or .hex file, specifying the family as **0xADA52840** (nRF52840) or **0x621E937A** (nRF52833).
To create a UF2 image from a .bin file:
```
uf2conv.py firmware.bin -c -b 0x26000 -f 0xADA52840
```
To create a UF2 image from a .hex file:
```
nRF52840
uf2conv.py firmware.hex -c -f 0xADA52840
nRF52833
uf2conv.py firmware.hex -c -f 0x621E937A
```
If using a .bin file with the conversion script you must specify application address with the -b switch, this address depend on the SoftDevice size/version e.g S140 v6 is 0x26000, v7 is 0x27000
```
nRF52840
uf2conv.py firmware.bin -c -b 0x26000 -f 0xADA52840
nRF52833
uf2conv.py firmware.bin -c -b 0x27000 -f 0x621E937A
```
