my mini is not recognised anymore by the PC, no activity when you plugin USB
the LED just lights up orange and stays like that
I am suspecting an issue with the FTDI USB chip. I also notice the USB port it used to reside in is dead too, not even power so I am suspecting a short might have happened
has anyone replaced the FTDI chip ? it is available from most distributors, going to be a challenge at 0.4mm pitch
can anyone help with reading resistance values on USB pinsâŚI see some inconsitancees
On the usb connector, whilst holding board with USB facing up, 1st pin from left (SSTX+)âŚto ground is only 16ohmsâŚall others(except grounds) are in the Kohms range
other than that all voltages seem to be there around the regulators
I have tried directly also, on 4 different PCâs now, the lime is dead and getting support, paid or otherwise seems impossible, this will be a deciding factor on my next purchase
yes i think it is the ftdi and i can probably source this chip and replace, but before i would like to know:
(1) possible to test/compare resistance values of USB connector pins to be sure its the chip
(2) see if anyone else has had this issue and if they replaced the chip and resolved it
(3) does the ftdi work âout of the boxâ once replaced or does it need some firmware
considering this has cost nearly $200 and support response seems non-existent
Crowd Supply brushing me off onto this forum saying 3 months warranty, when legally selling in the EU should be covered by 24 months, I believe I was supplied by a faulty device as this issue first started with signals disappearing then USB going dead, shame I left it on the shelf for a yearâŚ
anyway i am going to order a replacement ftdi chip and hopefully will repair it
going forward I have purchased an adalm pluto, order Friday from mouser in Texas â> delivered in Malta, Europe by Monday (the lime took 2 months!) and performance already looks better,and signals remain after 10 minutes unlike the Lime
So I will be recommending the Pluto over the Lime to any local hams
