Uhm, i see ..... i was thinking about switching the resistor on the opposite side, making two holes through the soldering pads, but i see from the pics that the place is already occupied from the switch, so no way ..... or, better said, still doable, but require to take away the switch, cut and rewire a pair of tracks ..... possible, but probably not for all the hobbysts (no offense intended)
The more easy system that i see, then, is to take away that resistor and substitute it with some SMD resistors soldered in "wafer" style, one over the other ..... if it's 0,22 ohm, you can use 5 x 1,1 ohm in parallel ..... the 1206 size (3,2x1,6mm) hold usually 250mW of power, so you end with 0,22 ohm 1,25W ..... considering that a diode like that one usually need 800ma ..... say 1A for precaution ..... 1A through 0,22 ohm is 220mV, and 220mV at 1A are 0,22W ..... more than enough .....
Being more precise, also standard low-cost SMD resistors in 0805 size (2x1,2mm) of 0,125W are enough, 5 of them hold 0,625mW, after all ..... and 1,1 ohm is actually an easy value to find ..... anyway, this take away the resistor from the transistor, and also give you the possibility to glue some piece of aluminium on the transistor itself, or solder a little piece of copper on its tab, or just fill the space from the module and the host with thermal conductive silicone glue, as i also sometimes do ..... this will improve the heat dissipation a lot
