Would the Picomite download work on this ?
Since it's the same processor ?

I made the assumption of Yes and grabbed a similar product

Apparently, it's sitting on my desk.

Might be able to test it in a few hours

Nice example of paying more and getting less. :)

This is the cheaper version.

MMBasic should run on any RP2040 board. Just watch out for any reserved pins though as they might not remain standard. You'll probably have to sick with the GPn terminology too, as board pin numbers will almost certainly be wrong.

Not exactly.

Smaller AND one analog input more.

Depending on what someone really wants and needs.

But comparing the price of course it is questionable.

Well, yeah...

Of course, if you are brave enough to remove Q1 from a Pico and dab a wire on, you too can have that extra analogue port - and keep everything else.

Actually, I like that module. It's a lot more than a simple breakout board (which I thought it was at first glance), more like a less breadboard-friendly version of the Pico and with more flash.

Does it not fit on a breadboard?

There is also another quite similiar board:

I meant the one posed by Tinine. It will fit on 0.1" centres, but that would imply padboard or a pcb, not a general purpose breadboard. You couldn't connect to it.

That one looks neat, Poppy. It's still twice the price of a full one though. :) I could see something like that being useful in a drone or something, to keep the weight down. You do get 8MB of flash though, and all four analogue ports too.

I only ordered it because it was cute

I do have a couple of standard Picos though.
Doesn't look like I'll get to my desk today though

That is exactly what I thought, too, just as a matter of weight.
Otherwise I think the Pico is quite small enough for most projects and ... for that tiny price.

I just would like to have more analog inputs and 4 is a good number.

Anyone having some very exact scales being able to tell the Picos weight?

I do just have one for kitchen stuff, not being very exact at all, but I guess the difference in weight would not be such an issue at all, probably the size.

So the tutorial for cutting the Picos tail off is quite interesting.

For analogues, a lot depends on the accuracy you want. You could, for example, use a CD4066B quad bilateral switch (and nothing else) to feed 6 inputs into the 3 on a PicoMite, using a single output to select which 3 you want. The accuracy may not be bang on and it may be a little non-linear (it won't be much worse than the straight PicoMite inputs), but it's probably repeatable and therefore predictable. (With a bit of fiddling and using all 4 switches with 2 digital outputs you can actually get 6 inputs into 2 on the PicoMite. :) )

Those switches are great!

If you feel like adding a SD card later they are easy to do and work very well. In the meantime you can always use XMODEM to save backups should you need to.

The Flash slots are great, especially now the system boots up with the program you were working on already loaded. :)

If you want even cheaper, and compatible with the pinout of the QtPy (and perhaps the Pimoroni Tiny 2040 too): Seeed XIAO RP2040.

Should even work with Cytron's (large, purple) Maker Pi RP2040 too.

Another one I use is the SparkFun Pro Micro RP2040. It has one of the I2C ports broken out as a Qwiic connector, but otherwise matches the old Arduino Pro Micro form factor.

The Thing+ RP2040 has an SD card slot, but not all Thing+/Feather format boards do. The daft SparkFun Thing Plus SkeleBoard I got on a whim certainly doesn't.

(I'm a SparkFun/Adafruit/Cytron/Arduino dealer, but probably not near where any of you are.)

Now that's a little powerhouse. Pins would certainly appear to be compatible with picomite MMBasic.

Where are you? I'm in Nova Scotia. There are about a half dozen Canadian regulars.

Thanks for your recommendation, I am just starting to figure out this alternative, I will check out the CD4066B

My two cents: I tried to load the firmware (5.07.00b30) onto the Arduino Nano rp2040 Connect and while MMBasic started and was responsive, the `Memory` command fails and causes a reboot, suggesting that the firmware does not correctly recognize the memory configuration (ie. the additional 16MB of external flash memory?)

nuke the memory before loading MMBasic

That's a very interesting module and it is even stocked by RS and Farnell
