Olimex has started to take pre-orders for the AgonLight2, a customized version of the Agon Light 8-bit open-source hardware computer based on the Z80 family and running BBC Basic.
Bernardo Kastrup and Dean Belfield created the Agon light 8-bit retro computer with VGA and PS2 keyboard port and programmable with BASIC earlier this year and released all hardware design files, the firmware, and documentation on GitHub, and Dean uploaded a one-hour-long video on YouTube. It was designed with EasyEDA, but Olimex re-captured the design in KiCad after getting customer requests, and the new cost-optimized board named AgonLight2 will start shipping by the end of January 2023.
AgonLight2 specifications:
The main changes made by Olimex are highlighted in bold in the specs above, but I’ll list them again for more clarity:
The new AgonLight2 supports the same Quark firmware as the Agon light with three modules: Quark BBC BASIC, Quark MOS, and Quark VDP which can be found in the GitHub repo linked in the introduction. Olimex talked with Bernardo to make sure it was a truly open-source hardware project before, and the updated board is now even featured on the official project’s page. The KiCad hardware design files and datasheets for the AgonLight2 board can be found on GitHub.
Olimex is taking pre-orders for 50 Euros for the AgonLight2, which looks like a pretty good price considering the Agon Light board had an estimated BoM cost of around $50 for a small production run. Shipping is expected to start on January 31, 2023.

What’s needed is a low cost battery handheld gaming device based on this CPU. To be used for retro Z80 Gaming.
Kind of disagree. The MCU is very slow. For handheld gaming device emulator probably could be better if something like Bouffalo Lab BL808 is used.
This looks like it’ll be cheaper than the BL808,.. has two Cortex A7s that run at ~1.3GHz, 2D hardware.
So what’s old is new again! Remember the Intel 8052AH-BASIC chip from around 1985? It was an 8-bit 8052AH microcontroller in a 40-pin plastic DIP package with a complete full-featured MCS BASIC-52 interpreter resident in the 8KB of on-chip ROM.[1] Home-made wire-wrapped 8052AH-BASIC single-board computers using a surplus Teletype Model 33 ASR (Automatic Send and Receive) teleprinter (or similar) with a built-in eight-hole punched tape reader/punch as the user console were popular.[2] The standard Teletype Model 33 ASR would operate at typically 60 or 100 words per minute (WPM, gear-set) using an upper-case only version of the CCITT International Telegraphic… Read more »
Female control port with 20 GPIOs
I believe the GPIOs are still on male headers, they just have a palstic shroud around them (similarly to the UEXT connector on the board).
Replaced the USB-A power connector with a USB-C connector as mandated by a new EU directive
Doesn’t the directive apply only to mobile phones, tablets, consoles and the likes in 2024 and laptops in 2026? The battery in this thing is optional, so I’m not sure if it would even fall under the scope of the directive.
You may be right. Maybe I misunderstood the text in Olimex’s blog:
We decided to replace it with USB-C connector which is used in all new phones, tablets and devices due to the new EU directive.
So I’ve change the text a bit.
WTF? Use a more powerful processor as a I/O processor for an 8-bit processor!?
