  • Nice in series, bad in parallel

    - PT4115 with standard wiring.
    - So it has capabilities for dimming
    - small
    - price is very nice


    - PT4115 is not useful for use them in parallel at the output.


    You can solder a wire to the DIM pin of the PT4115 and control it with PWM. It is also possible to reconfigure this wiring for 1,2A output (but change the SS14 with SS24 and better coil (coilcraft for example)). At the end it is a nice board for all PT4115 configurations, just use your own parts and configuration.


    Some pieces are at the maximum ratings at this board, but its cheap and easy to modify.
