I noticed it has a power input, obviously where u connect the 9v or 6v battery and those other white plastic bits look like the motor outputs (I think) but where are the signal inputs... The inputs that run from the microcontroller (atmega
I f u can find these then it looks ok (dont power it more than what its rated at tho or you'll blow the chip.)
Were the diagram pictures u posted the schematics for the motor driver? because I noticed it had an ldr (light dependent resistor). This is a sensor that can detect the density of light. it didn't look like the motor driver
I also noticed a DSE battery... Are u from australia? I find it very hard to find robot gear over here... If u wanna get serious I would recomend www.inexglobal.com
. look at the I-Box3.0 or Robobox3.0. I bought this with 3A motor drivers. costy but well worth it (u get stung with shipping costs).
Also if u are from AUSTRALIA (i'm from Melb) I can get this gear cheap (by cheap i mean no shipping costs) as I am a distributor. Send me a msg if ur interested
