Designed to power large motors at up to two amps using the excellent Hyperpopper solarengine designed by Brian Smith. This is very similar to the standard 1381 SE but includes a second 1381 which sets the reset level, meaning the caps do not have to fully discharge. This particular PCB allows for up to four drive transistors which means that if you use 2N2222's it should deliver up to 2A. It also has space for 4 diodes that can increase the trigger voltage by about 2v.
