Require a circuit designed for existing code that drives a stepper motor when buttons are pushed. I'm looking for a schematic as well as assistance in selecting a proper stepper driver and likely a boost converter. I would breadboard the circuit and test, i expect the process will require multiple iterations. I'm OK with purchasing multiple components for testing. I expect the active components will be attiny43u, stepper driver and regulator/boost converter. Stepper driver/circuity should be able to sleep - use minimal power when not active. I don't want to use a shield, would like stepper circuity to be able to be reproduced for a production pcb. I'd like to use a minimum amount of hardware. Do not require microstepping. Circuit will be driving either a 3V 1A or 5.4V 800ma stepper. Prefer using the first, but will depend on how much torque can get out of the circuit. The stepper will not be active often - only spinning about 15 seconds a day on average. Stepper is not energized when not moving. Goal is 6 months battery life assuming very low power from the attiny when not in use. Would ideally like to be able to drive all off of 2 AA alkaline batteries but I think current may be an issue. Options in order of preference are: 2AA alkaline 2AA lithium 3AA alkaline 3AA lithium I have no hard requirements for power usage during sleep, but it seems like some stepper drivers are 20uA in sleep mode, and attiny43u uses hardly anything - so 20-30uA should be very possible.

hi, can you test and confirm with a 3V supply if you're getting desired torque? then we ll decide whether to have booster. Which driver did you check for 20ua standby? we might have to switch off driver as well. How many inputs do you have? Are you programming your attiny through arduino ide?
