What is AgonLight2?
AgonLight2
is a re-design of the original AgonLight eZ80F92 retro computer, designed as a hobby project by
Bernardo Kastrup;
AgonLight2
is a complete Single Board Computer (SBC) with VGA display output, PS2 keyboard, and SD
card (acting as an external disk). This means that to write and run programs you do not need an external
computer like Arduino boards do;
AgonLight2
is BASIC-programmable microcomputer;
AgonLight2
has a GPIO connector with GPIO ports, I2C, SPI, and more signals, which are accessible and
can be used to interact with additional hardware (sensors, expansions, etc);
AgonLight and
AgonLight2
are Open Source Hardware and officially
OSHWA certified;
All CAD source files are available at
AgonLight
and
AgonLight2
GitHub repositories. They are released
under CERN Open Hardware License Version 2 – Strongly Reciprocal and allow users to learn, study, edit,
modify, produce, and sell same or derivative products based on these designs. The only requirements is to
open source their work under the same licensee.
The firmware of AgonLight is written by Dean Belfield and reproduces BBC Basic for Z80. The firmware is
also Open Source Software and available on
GitHub.
The same firmware works on
AgonLight2
without any
modifications.
AgonLight2
is RoHS, REACH, CE and UKCA compliant.
