 | | Is Expansion Board Servo Voltage Suppose to Be 9v
|
|
Hello again, I was surprised to find that my expansion board servo ports were putting 9 volts. Is this the way the board was designed or is this in error. Most servos I have come across work in the upper 4 to 6 volt range. The servo I have runs (...) (23 years ago, 15-Aug-01, to lugnet.robotics.handyboard)

Hi Chee, I have been told the power still needs to be supplied from that connector. My idea was to only use two of the four connecting pins (one for plus and one for minus) downward from the expansion board and solder two female connectors (one for (...)

Hello everybody, Is it a reason why the IRQ pin of the 68HC11 is not available. On the schema, seems that this pin is always up. If I look in the pcode.asm, the interrupt vector for IRQ ($BFF2) is set to RTI (BadInt) So, if I need to link a device (...) (23 years ago, 27-Jul-01, to lugnet.robotics.handyboard)

I think your trouble come from the H-bridge chip (L293D), it doesn't support more than 600mA of current draw, and reset or crash the board then this value isn't respected. To solve this trouble, I used instead the L298N, it support up to 1A. In (...) (23 years ago, 9-Jul-01, to lugnet.robotics.handyboard)
