Banggood BLF X6 driver not programmable any more

[Flashy_Mike]

@Gerrh

The BLF drivers from banggood are broken. I ordered 4 and the last two modes don’t work. They flash bright then go back to moon mode. I’m not very good at diagnosis of drivers, so I don’t know which part to replace. All lower modes work.

This is a completely diffferent thing. The driver needs some modification for high currents with PWM. Check this post and thread for help:

Does anyone know? Not sure which specific driver you are referring to, or which capacitors (there are no ‘input’ / ‘output’ capacitors on these drivers). Most sub-circuits need a decoupling capacitor, which is simply a kind of near-and-ready voltage source. The MCU should have one, located very close to it. On most drivers this is C1. On many drivers C1 is separated from the MCU by D1. In that case you should add a second capacitor C2 very close to the MCU. On most drivers C1 is also decou…
