I've spent several hours trying to figure out why my BX24 is resetting. I had the BX24 circuit running on a breadboard with zero resets for many months. I had a PCB made up and soldered the components on. The BX24 resets occasionally on the PCB. Somewhat randomly. No program changes moving it from the breadboard to the PCB. I am still not sure if i

I am doing my first 2 sided PCB using expresspcb .... What is the advice on which side to place traces ? Their tips section say power and ground on the bottom - but show a red trace example which is on the top - for their software. Is it better to have the majority of traces if possible on the top (component side) or bottom ? Their software defa

Hi, I am busy designing a base board for the BX01. Several of these boards will be networked together each with a specific function. The only problem is I am limited to 100mm x 80mm, single sided for the PCB, and thus I can not fit everything I would want on the board. My question is about the Reset switch. Is it really necessary and if not must PIN9 be connected to something, eg. GN...

FYI, Harbor Freight sells a 4" "Table Saw" that comes with a 1mm-thick 4" diamond disk. It makes easy straight cuts in ExpressPCB material, which has previously consumed a bandsaw blade per batch, with sparks. This is more like a warm knife through butter. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93211 Tom

Had a bad day here. I soldered all the components to my PCB today and tried it tonite. But the BX24 did not boot up properly. Most likely due to the fact that I used a machined-pin socket, and the BX24 pins don't fit properly in the socket (literally a square peg in the round hole problem). I haven't encountered a problem like this, as all other chips I ha
