I vehemently disagree with you. There are million dollar checks laying on the pavement, you just have to spend a bit of time outside of software engineering to see it. So much time is waiting executing rote processes by hand across industri

Good luck! I'm a big fan of the nRF52840! It's a great fit for a BT+USB keyboard. Hit us up in the blog post comments if you struggle with following Mohammad's instructions.
