What Hacker News says

After getting quite a lot of emails asking to buy one last time - I've put my Icepi onto Crowd Supply! This is a dev board that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB-B ports are replaced with 3 USB-C ports, and it has additional indicator LED and buttons. This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the product of multiple months of work. It is also completely open source!

In Icepi Zero – The FPGA Raspberry Pi Zero Equivalent Is Now on Crowd Supply

Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent

I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero! In case you don't know what an FPGA is, this phrase summarizes it perfectly: "FPGAs work like this. You don't tell them what to do, you tell them what to BE." You don't program them, but you rewrite the circuits they contain! So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB b ports are replaced with 3 USB C ports, and it has multiple LEDs. This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the product of multiple weeks of work. (Thanks for the pcb reviews on r/PrintedCircuitBoard ) (All the sources on github under an open source license :D) PS.
