2016年7月5日 · As Aodhan145 said that sort of power supply is probably your best bet. The other alternative is if you can get hold of an old PC power supply from somewhere.

2021年10月1日 · Good luck! edit: the LM337 on this board is a variant of the SMD D2PAK TO-263 package. These dont normally have the mounting hole though. These dont normally have the mounting hole though. You can easily buy the D2PAK variant without mounting hole, but I bent the legs of a TO-220 to save buying more parts.
