Atmel ATTINY2313 Opto isolated Board with DC motor Firmware
100% optoisolated. No frustration due to abrupt microcontroller (uC) reset during program execution
especially when running low cost motors and having a state based design.
********************************************************************************************************
This offer is for ATTINY2313 programmed with DC motor driver firmware. The Board accepts two DC motor from 3V to 12V The control signals are PWM and Direction for each motor. This board offers the highest noise immunity as high powerdriver circuit is fully isolated from control circuit consisting of Attiny2313 connected to your microcontroller. This is important when using microcontroller's onboard analog to digital convertor to read sensor inputs etc. The noise in the coupled circuits is the main reason for uC hang and failures.

More Details about this board:-
This intelligent board does high speed processing (16Mhz crystal) and reduces the number of I/O and processing overhead otherwise required by the main CPU ( AVR or PIC ). Free from latchups and resets, this board offers the highest immunity to electrical noise. This board can support low voltage motors from Tamiya. It can work as standalone fully functional Robot controller. Like line tracing, obstacle avoidance, light following robot or bluetooth controlled robot. You may need a suitable programmer to configure this board for other application. We however adjust the fuse bits to external oscillator (16Mhz crystal). Hence you can use low cost programmer.
Main Components 1X ATTINY2313, 4X Tip 122, 4X Tip 127 and 8X sharp PC817 or equivalent optoisolator.
Other Applications:-
1) Stepper Motor. Can drive 2 stepper motor (unipolar).
It can also drive a combination of 1 DC Motor and 1 Stepper motor (unipolar).
2) 8 Relays. Use RS232 (TTL levels) or SPI interface 6 pin ISP cable from Arduino. (Please see our other auction).
3) DC to AC conversion.
