Ok, boards ordered. Shipping was stiff: C$75 (saying I'm in a "remote area"). There may be customs duty.

If anyone else in Canada is interested, one more will be available. Cost is going to be about C$50 plus Canada Post shipping.

okwatts--yes, I'll include the RPZ baseboard and all addon PCBs--gratis.

Is there a 5GHz wireless option that uses the same pinout as the Raspberry Pi 2.4GHz module? My 2.4GHz band is getting crowded.

What enclosure will fit it? Also, are templates for the front and rear panels available?

Micropython running on the Pico Computer 3. Still a lot of work to do to enable all the peripherals but the core is now working. Looks like USB host will be the hard one Micropython hasn't got any USB host functionality.
The intention is to make this a fully self contained environment with editor etc.

But does this mean 32bit integers?

Posted: 09:47pm 01 Jul 2026 Copy link to clipboard	matherp Guru

Can be either 32 or 64 and floats can be single or double - haven't decided yet

Bravo, Peter!
It's a great idea to port MicroPython to Pico Computer 3.
So maybe we'll even port MicroLua next!?

Looks like BASIC

local gpio = require 'hardware.gpio'
local pico = require 'pico'
local time = require 'pico.time'

function main()
local LED_PIN = pico.DEFAULT_LED_PIN
gpio.init(LED_PIN)
gpio.set_dir(LED_PIN, gpio.OUT)
while true do
gpio.put(LED_PIN, 1)
time.sleep_ms(250)
gpio.put(LED_PIN, 0)
time.sleep_ms(250)
end
end

Quote Does MicroLua support other microcontroller families?
Currently it doesn't,

Not true. One of the C compilers for the Propeller includes a Lua interpreter.

For Grogster - are you planning to get some Pico Computer 3s? If so, please put me down for 2
Cheers, Doug.

also for Grogster, +1 for me (everything included)

G'day,
Grogster, +1 for me, might be +2 but I need to contact someone on the second.

Regards, Lyle.

Grogster +1 for me also mate

I did try to order some but after uploading to JLCPCB they put it straight in my so called project folder which won't display it.

One note to anyone ordering. I don't know if JLC have changed their process in some way but I have found on my last batch minor issues with what appears to be some residue on the boards. On various boards I have had to spray the SDcard, or one of the USB ports, or the boot switch with contact cleaner to get everything working reliably. Typically they work without issues, but if you see any issues, contact cleaner or IPA will fix it.
This last batch are the first for a while I have ordered in red. I don't know if the different colour solder mask might be the issue but if you do have a problem it is easily fixed.

Ok finally got it sorted with JLCPCB now it did say the wfi chip wasn't available also it said 10K resistors weren't either so that has me worried.

The price for 5 of them is $266 but the cheapest freight brings the order upto $366.75 so about $73 for each board.

Does that sound right or not ?

Regards Bryan

The shipping sounds very expensive compared to the UK. I'm not seeing any shortfall on resistors - there is on the psram chips. The only thing odd on the components are the two three pin headers where if you want them to include them you need to check the boxes.

Posted: 07:47am 04 Jul 2026 Copy link to clipboard	Bryan1 Guru

Ok I talked with support and reloaded uploaded the files and selected different 10K resistors, now only one board will have the psram as thats all they had and no wifi chips either.

So got the total cost down to $256 for 5 boards so for Australian members got 3 boards for the cost + shipping.

Regards Bryan

Edit: lets make that 2 boards as I'm sure Lyle would want 1

Please post details of the part number of the replacement resistor (Cnnnnn) in case anyone else hits this.

Posted: 08:02am 04 Jul 2026 Copy link to clipboard	Bryan1 Guru

Didn't see your post mate while I was in the shed but what I did find after I clicked the search button a new page came up with 10K resistors so just chose one where they had plenty of stock.

Now I did ask about the $99 shipping and was told they will refund the extra which they did

Bryan,
I'll take one of the boards

Cheers
Geoff
