This A$50-A$60 board includes a 0.96 inch ST7735 TFT as well as includes a few different camera options OV2640, OV7725 or OV7725 M12.
Board has 8Mb SPI Flash + 8Mb QSPI, microSD, 8bit DCMI, USB-C connector, three user buttons, user LED, Boot and NRST buttons.
The CPU is the 480Mhz ver V 144pin chip.
2.54mm breakout pins.
Sold on AliExpress.

Might be worth trialling Armmite 5.07bO016 on this and see what is involved in making it work??

Peter??

Just know enough to get me in trouble, but not quite enough to get me out.

@HardingJohn

Was there supposed to be a link?

Can't find this item on AE.

This maybe

Different CPU, different RAM, ...

Going to need work.

I have that very device but @HardingJohn states:

This chip is 100pin

I wouldn't spend too much time porting to this board, not at least until next year. Once WeAct's stock has gone, that microcontroller hasn't got a expected manufacturing date until Q2 2023.

WeAct's board is a clone of the OpenMV board. I'm an OpenMV reseller, and they've told us that there's no new supplies expected for more than a year. It's an amazing board, just unobtainium.

Meh, the Parallax P2 is mind blowing. I have 12 closed-loop CNC axes running on a single-chip (8 CPUs, mind). All PID loops are running at 32KHz, not using a single interrupt and the darned thing hasn't broken a sweat.

8 processors and 64 "Smart Pins" that can be whatever function you need...Yeah baby

Oh and I program it using BASIC

But the I/O etc?

Needs all new code? Won't run MMBasic as-is?

So, could MMBasic run out-of-the-box on a STM32H743II OpenMV Cam ?
This one is so sexy, and may be a total real-world platform for MMBasic

Why not get one and let us know? ;)
It doesn't appear to be available yet, according to that link. Do you think it will be? And when?

It has less I/O than a Micromite and you can get a lot of PicoMites for that amount. Admittedly, it does have a camera. lol

Check all (that's ALL) the I/O pins are OK with MMBasic as it is for that chip & the kinds of added RAM & flash & the addresses they are at (i.e. how they are wired).

Every difference means another software change of course. Some easy.

I would say that a better solution would be a cheap or unused Android phone for the image capture/processing and Bluetooth or WiFi to your MCU of choice.
The phone can also send messages which is useful for security applications.

Battery backup power and nicely packaged.
