The parts list says R1 is 3.3K, but the schematic shows it as 68 ohms. Which is correct?
@WK: sorry for the inconsistency. The part list is updated now.
thank you plenty of used aa batterys to use
thanks cliff
Sorry for my poor English
I soldered the v1.1 on a perfboard, the mcp1640 is too tiny for me, i bought a convert pcb to convert SOT23-6 to DIP package and it’s works finaly.
The version 1.2 can output at 1A?It’s great, but where is the parts list for v1.2?
Thanks a lot
I haven’t had time to prepare the part list. But you can open the schematic in EagleCad (it’s free) and check the part number in the schematic. You can also export a part list in EagleCad.
