AgonLight2 Single Board BBC Basic Z80 Modern Retro style Computer
AgonLight2 is OSHW certified Open Source Hardware with UID BG000090
AgonLight2 is a re-design of the original Open Source Hardware design of AgonLight made by Bernardo Kastrup a.k.a. TheByteAttic. The firmware is developed by Dean Belfield.
AgonLight2 is not a emulator, it uses modern ez80 processor which is new improved version of the classic Z80 which can address up to 16MB of memory (24 bit address bus) and runs at 20Mhz!
ESP32-PICO-D4 is used as sound and graphics co-processor.
The micro SD card acts like disk drive where you can load and save programs, write and read data.
UEXT and GPIO ports allow AgonLight to interface outside world with digital Inputs, outputs, SPI, I2C, and UART.
LiPo battery charger allows the whole computer to run for hours on single LiPo battery even if no external power supply is present.
Color VGA output supports 320x200 64 colors, 512x384 16 colors, 640x480 16 colors, 1024x768 2 colors.
AgonLight2 combines retro with modern, you can do old school games and at the same time you can do also small home automation jobs, attaching different sensors and relays to the UEXT/GPIO ports.
