  • I got one of these to use in a picaxe 18 high power board (CHI035). It does not work as well as an L293D.
    I used the CHI035 to replace an 08 based picaxe motor controller which includes an L293D. That controller was used with a Tamiya tracked chassis and it worked fine.
    Once I placed the CHI035 (with this chip installed) on the track chassis, this chip would quickly heat up and the voltage would start to drop. With in a few seconds of operation it would drop below 0.5V.
    I replaced this chip with a REAL L293D and it works perfectly.

No public wish lists :(
