I see from Phil's BoM that he has used a 7.5ns CPLD.
The ones I have are 10ns 288s, as per TF's original BoM. Will these still work with the posted firmware?
Mine is 10ns,

In my case the 7.5ns ones were available and the 10s weren't.
I also got the 7.5ns after others had said the 10ns ran hot.

Good to know, thanks for confirming.

these was hot due floating pins, not because pin to pin acessing time..

Yes I know it was because of the floating pins but the 125mhz CPLD on my board never got warm with the floaters.

Hey TF, I'd like to buy a few boards off you if you have any left or go on a list for your next run.
Off topic, I looked at the JLCPCB SMT assembly service and noted their parts format. Is there any tools out there to generate the JLC BOM format from an EAGLE BOM or did you do it by hand or write a python script?

I'm freezing all board sales and probably going to ditch all the current designs in favour of Lattice based solutions. This is due to the spike in Xilinx prices. Do not buy any Xilinx chips in anticipation of TF boards coming out because they're probably not going to use them now.

A quick question @terriblefire ,, which range chips and programmer?
Just want to check prices for stuff, so I can be geared up ready if you go the lattice route

Will be the ICE40 chips. They can be programmed by SPI so probably be a RPi for a programmer.
