Openbench logic sniffer - pull-down wing - Rev 0.1
| |
|
It turned out that the pull-down option worked best with 10k resistors, so this is a smaller board with just that.

MBI5168 breakout board

I did a test assembly. The potentiometer is not the right kind (wrong package and wrong resistance range), but it works ;-) It can easily be used with the arduino ' shiftPWM ' library. Up to 100mA per channel if you keep an eye on the chip temperature.
Made with KiCad .

OLS pull-up/down wing

I'm still experimenting with the size of the resistors. 10k pull down seems to work reliable, whereas 10k is only good at 5V/3.3V pull-up voltage, 2.5V needs close to 4k to work reliably.

Sometimes hot glue is useful

When used it is powered by a 5V boost converter that sucks the last bit of energy out of 2 old AA cells.
