| | Re: handyboard clock speed
|
| (...) yes, this is right. the fastest you can go with the 52-pin 6811s is 12 MHz crystal --> 3 MHz system clock (i'm pretty sure). so this is only 1.5x over the stock HB. so you've got the issue Curt pointed out with not only the downloader, but (...)

| I have an old 'wall wart' lying around. It has a rating of (12 vdc 1 amp output). i was wondering if i can use it on the handy board. the specs i read about the handy board call for a 12v 500mAmp output. any response would be appreciated.

| | Re: charger
|
| the main reason this doesn't work is the 1a supply produces too high a voltage at the actual current being drawn, resulting too high a charge rate. technically, it will work in NORMAL charge mode, but you'll be charging the battery too fast, (...)
