There are a limited number of ULX3S FPGA + ESP32 boards available at Mouser Electronics. @gmahovlic.bsky.social for more details.

If you want one, now is the best time to order it. Makes a super cool gift. Yes, Christmas is month after next. 🌲

Thank you @BalCCon it was amazing experiences to be part of this super cool conference! This year I have talked about #ULX5M board that is hosting #EU #CologneChip #GateMate chip, held small talk about #RadionaORG #ZigZag badge and had #Assembly where it was possible to assemble personalized badge!

As I did not post for a long time I will start from an end. We got #ULX5M-GS up and running!!! #CM5 pin compatible #FPGA #SoM with #EU Cologne #GateMate A1 and fully open source toolchain. Still lots of work left, but I am really happy to see DVI out!

Recently received an Radiona / @intergalaktik.bsky.social ULX4M_LS and lot of extensions board for @olimex.bsky.social GateMate A1 EVB 😍 Thanks @gmahovlic.bsky.social !
Started with ULX4M_LS support in @enjoy_digital LiteX:
- SDRAM: ✅
- Ethernet: ✅
Time to cleanup target and create a PR!

wolfSSL had an amazing visit to #Radiona! Huge thanks to Goran Mahovlic and the team for the warm welcome and the opportunity to present wolfBoot at the OpenHardware Meet-up. Projects like the #ULX3S #FPGA + #ESP32 are truly inspiring!

@wolfssl.bsky.social wolfSSL v5.8.0 of the Arduino library now available! Install directly from the Arduino IDE. Includes examples, plus newly added AES CTR demo.

All the latest cryptographic algorithms, #TLS 1.3, post quantum, and more. NIST FIPS 140-3 certified.

#ULX3S ESP32 updated to ESP32S3! USB is now directly connected to ESP32 so we do not need FTDI. emard already has initial support with drag and drop bitstream.

And there it is, the slowest #riscv core? Running on the time multiplexed NAND gate (bsky.app/profile/thez...)

The display is showing the PC value. It is running a program to add 1 to a register, and it with 1, and skip an instruction if the result is 0
