Damm I am trying to get this working with a Arduino pro mini ,,but no luck wanted to use it in the car ..
How do you wire the NRF24L01+ ???
N-Channel Mosfet s ??? model number please any help much appreciated
I have tried mosfets >>>irf510n
To provide a large enough pulse to drive the ceramic transducer , you need a lot of energy, so they pump up the 5v with an inductor/transformer to provide a high voltage pulse. This is 60v or more…
The more Energy you produce the farther the pulse will travel….
Everything thing else on the board run at 3.3 to 5V.
Add a large Capacitor of 100 µF are so between the 5v and ground on the device, this may clean up your problem.. Some CPU modules just can’t supply enough current quick enough that’s needed when the pulse is triggered.
These are very inexpensive device, we’re luck to see them work at 1/2 the spec range.
@Andrew-Currie Downloaded KiCad and used it to import jBoard2.brd and output .gbr files via Plots plus the .drl file. Checked using GerbView and uploaded to PCBWay. Hopefully this will now work...
@gohan I live in Switzerland, but perhaps my place has more humidity than normal.
It's not silly problems we're working on, we're learning all the time!

Hi: (Please direct to Feanor-Anglin if possible)
I previously ordered some 4RelayDIN PCBs off openhardware.io and got v1.6 PCBs but the info on the site I found is only for an earlier version of the PCB board.
I am trying to build some of the boards but there are additional compomemts on the newer PCB board.
The main one which looks to be a driver IC.
Would you please share the updated information with me or perhaps update the openhardware.io site.
Many thanks, Rod
