open-source teensy-compatible - what features do you want?

interesting
$15
i am sure someone here has tried it already
anyone ?

Initially, I thought that it could be easier with STM32H7 to have a lower cost board.

While investigating about i.MX RT (Crossover MCU) series, I found that there is already a low-cost full open source board at US $15.00. The Olimex RT1010-Py.

It's using 500MHz MIMXRT1011DAE5A (LQFP-80 0.5pitch 12x12mm). MCU is US $4.31 single qty and $2.72 @100 PCS. Worth looking.

Sure, RT1062 or STM32H7 will have much more peripherals. But this is 32-bit MCU 500MHz LQFP-80 for less than $3. Amazing.

Not sure if this 'idea' still has a pulse, but there are shiploads of generic PICO boards out there, and for low prices
It could make more sense to be a little different/better in some technical areas, to open new markets, rather than try to clone lowest common denominator parts.

One obvious area is to upgrade to a TCXO for better clock stability, to open up timing and metering uses.

also, we’ll be doing an esp32 p4 version.

The default PICO clock is 12MHz and the P4 default looks to be 48MHz.
12MHz TCXO are a little rare, and are generally larger.

lcsc do have OW2EL89CENUXFMYLC-12M  12MHz SMD3225-4P  ~40c/500
Smaller is less common, Digikey do have RTXE-2016ED333-C-12.000-TR in 2016 package, but for a spenny $1.99/500

Another option would be to look to 24MHz and divide by 2 with an AUP1G80 FF, powered off PICO core Vcc.
lcsc have T024000VX 24MHz SMD2520 31c
OW7EL89CENUYO3YLC-24M   SMD2016 44c

or maybe 48MHz for both the P4 and Pico 2 boards (with AUP2G80)?

YXC_OW7EL89CENUXK7YLC-48M_C48888237_TCXO_48MHz_3v3_500ppb_CSW_SMD2016_30c

Or you could add a Si5351A/MS5351/MS5352 and use the most common TCXO (and thus lowest price/ easiest to source) of 26MHz
OW7EL89CJNUXK7YLC-26M  26MHz SMD2016 ! 24c
2T026000VX 26MHz  2520  24c

You joined up today and have commented only on this fracas. Strange how this place was never useful to you before now.

That's a very fair point. Maybe I only watch Dave's videos, maybe I was lurking on the forum for years, maybe it's an alt account or maybe I'm just a troll. Maybe all of the above or maybe none... That's for you to decide.
I found this "issue" polarizing enough that I wanted to share my opinion (even though why should anyone really care about it?).

And then had no further interest in the forum after 22nd January. Maybe this particular argument was your whole life here after all.
