Hi,
I would like to have a chat with someone technical. I have a couple of units in the field and for some reason the 2nd one just died today. I am yet to find out what happened to the first unit that died but it seems like there is no power if you power up the unit via the DP power module.
I use a Fez2 with GPRS module, USB client DP power module , Rs232 and LED strip.
Any ideas or suggestions why this unit would just die?

Do you mean Fez Spider 2? Cobra 2?
@ riaan.mastenbroek@ gmail.com - As @ Brett asked, which specific board are you using? When you say it died, what exactly about it doesn’t work anymore?
Hi,
Sorry for my late reply, I am working with my installers in South Africa to figure this out and due to time zone differences I could only get a response now. The issue is that they are daisy chaining 2 or more Rs232 connections on one Rs232 port in my device. For some reason it seems like it creates a short circuit and blows the unit. It is sporadic and I am not sure why it is happening.
The unit is a Fez Spider 2, sorry for not being clear on that. I went for the most expensive power supply and according to my devices and when I do a quick power calculation it seems fine. I also tested the unit and the power supply did not get hot at all.
The one unit that “died” - I am not sure what happened. The installers just said that if they plug power into the unit it remains dead. I am in the USA for 2 weeks so I will only be able to test this when I am back in South Africa in 2 weeks.
For all that contributed to this forum, thanks for the effort.
This is a great product - I moved from Netduino to this gadgeteer platform and have provided a solution to the South African farming community using gadgeteer - and it seems like I will be buying many many more devices soon

@ riaan.mastenbroek@ gmail.com - As soon as you get back we can look into it more to see if it’s truly dead. I’d start with putting it in the low level GHI bootloader to see if it comes back and you can update the firmware. If there was a short in your system though, as you can expect, there is little we can do for that. We’re glad to hear you’re liking the platform and getting a great use out of it.
