content: Good afternoon (o;Looking for a inexpensive Lattice ECP5 board, I stumbled upon this manufacturer code which seems to be from Lattice Semiconductor, but neither Digikey has a datasheet nor is this device number known on the Lattice site.Does anyone knows what exactly this LFE5UM5G-85F-LMP-EVNG is? Or has a link to a datasheet/board description/manual?thanks in advancerichard

content: Seems to be a new board or something else....as in the links above the part LMP in the part is missing.Digikey lists them with around half price as the boards without "LMP", but available somewhere in November:Reason for asking is that I am looking for affordable ECP5 boards for testing my GUI wrapper FPGA IDE for macOS which uses as backend the yosys/nextpnr tools. And as yosys/nextpnr support for devices is limited, the choice is to test with Latticesemi and Gowin devices.

content: That board was released in 2018, 6 years ago.If it has everything you need on it, then buy it.If you want optional onboard goodies like gigabit ethernet, DDR3 ram chip, DisplayPort, PCI express... there are newer boards which have those as well as the 5UM5G-85 FPGA onboard. But, those boards may cost more.

content: For Lattice dev boards, if you want DDR3 RAM, PCIe and whatnot, your options are the Versa boards. More expensive than the basic dev boards of course (around $380 for the ECP5G).

content: Sadly Latticesemi doesn't have those regular Versa boards discounts anymore where they did sold them for a limited time for US$ 99 (o;Here's a quick look at how my wrapper might look like in the end (heavy work in progress atm ;o)

content: Yep I got one with a ECP3 back then for $99. But prices for Lattice dev boards have literally exploded in the last few years anyway...

content: We *may* have the Versa board in the office. Was a Lattice fan but received less than zero factory support. Each request was pre-qualified with a sales call on how many containers of their device do we plan to purchase. These days, chasing Gowin and reporting IP bugs - latest was their EasyCDR IP - broken out of the box demo.Is the Versa board of interest to you? Will be going into the office for a few hours and can check our inventory. Fairly confident that we purchased at least 1 and perhaps 2 of these Versa boards. To be confirmed..

content: Well sure I would be interested....But I assume shipping from Canada to Switzerland or Germany would cost much more than the card itself (o;

content: TBD. We ship worldwide daily so have some incentives with the couriers and then there is Canada Post if you are not in a super rush. Let us first confirm what we have in our inventory. Then can ask our shipping to get a ship rate estimate.
