If you happen to have the incompatible module, see issue #31 for possible solution. + * The incompatible MT3608 'clone' causes calibration issue and basically breaks the variable voltage functionality. This can be fixed by replacing the 2k2 resistor located on the module by a 15k resistor. + * Bellow is the image of the old (compatible without a mod) and new (require the resistor mod) MT3608 modules. If you happen to have the incompatible module here are the steps to replace the resistor: + - heat up a soldering iron to ~350 deg C and put a medium sized solder blob on its tip + - touch the tip of the iron in the middle of the resistor for a second + - gently press on the resistor and slide it off the PCB. + - the resistor footprint allows to solder new SMT or through hole resistor + ![mt3608_modules](https://github.com/ole00/afterburner/raw/master/img/mt3608_modules.jpg "mt3608_modules") Troubleshooting:
