I’m using a Micro:bit board for my project. I wanted to update the firmware on the board and I went to this link:
I found two firmwares. One for the freely given boards and one for the commercial ones. I was surprised to find that the firmwares have a large size difference. UK-free is 97KB, commercial is 267KB. Here’s my inquiry:
- What’s the difference between the two?
- Are the Daplink chips different on these two boards? (KL26Z)
- Will the chip work if I interchange the firmware, i.e. if I load the UK-free hex on the commercial or vice versa, will it work?
Please help me with answers. Thanks in advance.
