Here's the Forth for it, which can replace its initially built-in BBC BASIC: https://github.com/lennart-benschop/agon-forth

What is it?

A new, compact retrocomputer. More details here: https://www.thebyteattic.com/p/agon.html

My impression is the only thing built-in is the MOS operating system.
Yes, I saw that. I'm not sure what it is useful for. It seems to have no async serial ports, but does have a Z80 CPU. I would like to see something like this, but with hardware serial ports.
What is the intended market? Is there one?

I made a figForth version that was an improvement over the original figForth. Anyhow the original figForth should run under CPM2.2.

From what I see also at least VDP probably must be flashed (see „Update steps”):

Looking further that $40 microSD card appears to be a bit of entrepreneurship by the local vendor. Agon manual indicates BASIC and MOS are free for the downloading. Updating the firmwares is probably the main issue (and finding room for another monitor, keyboard).

requires no host PC: it puts out its own video (VGA), audio (2 identical mono channels),
accepts a PS/2 keyboard and has its own mass-storage in the form of a µSD card.
As a microcontroller, it has a control port featuring SPI, I2C, twenty or more distinct
GPIO lines (including lines for serial communication), a system clock output, as well
as power (3.3V and 5V) and ground rails.”
What is the intended market? Is there one?Mainly retrocomputer enthusiasts, electronics hobbyists, radioamateurs etc.
The only mention of serial port I/Os I can find are between the Z80 CPU and the ESP32. Is the ESP32 on this board? The hardware manual doesn't mention the UART(s), so I have no idea how to use them. Is there a software user's guide or something todefine the programming of this board?

Dear Ricky,
1. „As a microcontroller, Agon light™ has a control port featuring SPI, I2C, 20 distinct GPIOs (including UART lines), a system clock output, as well as power (3.3V and 5V) and ground rails. It also features a separate ACCESS.bus header.”
Noticed „including UART lines”?
You may want also to have a look onto this: https://github.com/envenomator/agon-hexload
(„The UART1 serial port can be used at the external GPIO serial pins PC0/TxD1, PC1/RxD1 and GND. Connect to external serial interfaces (3.3v), like for example a USB-Serial FTDI adapter” etc.)
2. Regarding software user's manual: you may want to check out closely Agon Light Wiki:
