The Wiki > Hardware Requirements > Coils page is your friend. ;) Any device or module with a high-voltage power transistor or IGBT to switch coil power power to ground (completing the circuit).


Simple 1-channel (1 coil) examples often used are the J121, J701, PRW-2, and many others. Multi-channel types are common and popular, such as the Bosch "211" 4-channel module for multiple coils. Do a search here for designs to build your own if you prefer. See the Wiki for distributor wiring concepts here.
