I recently bought an ODroid HC1 (http://www.hardkernel.com/main/products/prdt_info.php?g_code=G150229074080) but didn't think to purchase a USB-UART module to use for serial debugging.

 

Posting here on the off chance that another ODroid user has a USB-UART module (http://www.hardkernel.com/main/products/prdt_info.php?g_code=G134111883934) lying around they don't want/need that I can buy cheaper than ordering from hardkernel.com (US$19 shipping!)

 

Thanks in advance,

 

Phill

@getresults What do you need this for? The pain here is the UART on the ODroid is 1.8v I believe (so won't work with a standard 3.3v or 5v cable). You could potentially use an Arduino if you need it for something small otherwise I think you're stuck with ordering it from Hardkernel.

Hey Michael!

 

I am having boot issues with my HC1 and OMV - something keeps changing on reboots.  The HC1 comes up ok and shows the blue heartbeat signal but it's no longer possible to connect - ssh, http are no longer active. 

 

So I'd like the UART cable to get access and see what is causing the boot to fail.

The Odroid UART module is capable to adapt to the relevant voltage (1.8-3.3V) of the board in use.





Nope, English isn't my mother tongue. But that's why I'm here. smile
