Jfcatari Posted March 18 Share Posted March 18 I am not familiar with the other board that Gavin was using, so I can't comment. Quote Link to comment Share on other sites More sharing options...

I'm not talking about the board from Gavin but this V4. That is the one I have now. The switch is in it but I want to know if it is possible to add the leds to either the sio board or maybe directly to the arduino Quote Link to comment Share on other sites More sharing options...

Mr Robot Posted March 18 Share Posted March 18 Gavin never shared the Gerber's or even the schematic for his revision of the board so I don't know what he did exactly. From the looks of it he just added a resistor and a trace to the power line for the power led and got the act led from a couple of points where the pcb solders to the uno. If you follow the traces from the led pickup points to the other end you can see where to tack a wire to pick up the same levels. you will need to measure the resistance on that 3rd resistor to see what value it is and use a similar value if you want the led to be the same brightness.

Well if I compare both boards I see that Gavin used a 2nd row of pinheaders to connect it to the arduino. On the board itself are 3 resistors and a chip. Besides that he added connectors for the 2 leds, switch and sio cables so you don't have to solder. The connectors I don't care but it would be nice to use the leds in combination with the V4 revision. I'm not good in doing it myself so I hope to get some advise.

Hello @tajvdz it seems that no-one has the interface board that you have to work from. The two rows of pin headers you mentioned have been custom installed and not all Arduino carry these connections anyway. Yours is considered to be the Bestduino for the S-Drive Max and modified to suit. Are you able to remove the SIO buffer from the Arduino and supply images of both sides of the board? Then maybe we can figure it out. What instructions did you receive with your S-Drive Max did it all arrive pre-assembled? The three resistors have values of R2 & R3 4.7K Ohm and will be the pull-up resistors for TX and RX, and R1 10K Ohm possibly feeding the power LED although this seems a bit high so may be another pull-up resistor. The chip is most probably a 74LS07 hex buffer. I am not entirely sure why you need the extra LEDs though, as the display itself indicates that it is on, and there is an activity indicator in the top left hand corner of the display?

I got the whole thing assembled about 4 years ago. Stupid thing is that I made a mistake with connecting the sio cable so it doesn't work anymore. I'm also unlucky that no one is making it anymore. I'm not able to remove the upper board myself. I like the 2 leds mounted to the case. It adds a nice feature. That is why I bought it..

I think it must be possible to add the leds directy to the arduino or not? Quote Link to comment Share on other sites More sharing options...
Mr Robot Posted March 26 Share Posted March 26 Yes i expect it’s pretty simple, if you have the original board, to follow the traces. At most it will be one resister and a couple of wires. If no one else has that board, no one else can help you. I don’t know how much more help anyone else can offer, it’s pretty much up to you to work it out and share the info so it can help the next person looking for this info.

That is why I bought it completely. But I see that it is possible in combination with a uno2sio board. So you only need 2 wires from the arduino?

Honestly, it requires technical skills and electronic knowledge at primary school level. You need 4 wires and 2 resistors: A +5V --------- [1kOhm]---------------(longer leg) [LED] ex. RED (Power LED). R GND ----------------------------------(shorter leg) D U +5V ----------[470 Ohm] ------------(longer leg) [LED] ex. GREEN (Activity LED) I RX ------------------------------------(shorter leg) N O You can see where and how it is connected in the pictures, it can't be explained any easier than that. 1 Quote Link to comment Share on other sites More sharing options...

tajvdz Posted March 26 Share Posted March 26 Ok. Does it matter on which of the 2 wires you put the resistor? Quote Link to comment Share on other sites More sharing options...

It does not matter whether the resistor is in front of the diode or behind it. It only needs to be in series with it, in which case the excess voltage will be deposited on it. It is a matter of convention to place it on the + side. The most important thing is the correct polarity of the LEDs.

tajvdz Posted March 26 Share Posted March 26 Ok, so here you have to connect the wires with 2 on 5V? Can I use the holes next to the connectors for the screen? Where I put the red dots or do I have to use the other that are used for the screen connectors? Quote Link to comment Share on other sites More sharing options...
madness77 Posted March 26 Share Posted March 26 You can use the holes. Quote Link to comment Share on other sites More sharing options...
tajvdz Posted March 26 Share Posted March 26 Ok. That is not that hard. By the way ignore the uno2sio board. It is just an example. I will use another arduino with v3 or v4 uno2sio board. Why are are the letters arduino here? I don't see them on my version. Where is it for? A +5V --------- [1kOhm]---------------(longer leg) [LED] ex. RED (Power LED). R GND ----------------------------------(shorter leg) D U +5V ----------[470 Ohm] ------------(longer leg) [LED] ex.
