I’ve modified a few Nanjg’s with FET’s, & reflashed without a problem, but today I built my first BLF17DD board from scratch. First scratch-built board, & first time using hot air reflow & solder paste. I’m happy with how it all went together - very neat with the solder paste & hot air - makes it pretty easy
I got a few kits from RMM - it’s the Rev2 board, & I’ve changed the CAP location from B+ to GND & bridged the R3 pads.
Problem; Works fine on high / turbo, but on low it will work for around 5 seconds, then start to pulse at around 2Hz.
On Medium modes, it will also work for a few seconds, then will start pulsing & also changing modes randomly.
I’ve tried several different firmwares, & tried fast & phase-correct PWM, but it makes no difference.
In addition to this mode memory does not work in any of the firmwares I tried.
Anyone come across this type of behavior before? I’m thinking that the ATtiny may be faulty.
Thanks.
