/diy/ - Do It Yourself

>>1119153
The f1 chip itself isn't obsolete, but a miniquad flight controller based around it is. The hobby has moved on & people now expect faster PID loops (f1 struggles to achieve 1KHz loop with 1KHz gyro sample, people now want to run 4-8KHz+) & only having 2x UARTs is very limiting - if you have USB on one & your RC receiver on the other, you have none left for telemetry, OSD, etc. & have to resort to softserial.

Banggood is my usual source for RC stuff from China & there are plenty of f3 boards. I've used these for my last two builds, but there are cheaper options available without built in power distro.
