List of cheap ARM MCU development boards

I got mine a month or two ago (I was an original backer; it was delayed by months), but haven't played with it yet.  More info on the board here.  For me, the main point was that the Amlogic AML-S805X support should be upstream; no vendor kernels, can use standard Linux kernels.

(So it is not a microcontroller, but a full Linux single-board computer with HDMI output, in case anyone is wondering.)

Just added the MIMXRT1010-EVK, the new sub 10$ evaluation board from NXP with their i.MX RT1010 Cortex-M7 (500MHz with high speed USB)

$10.10 is surely just the promo price. Regular price must be closer to Digi-Key's $84.

Its $10 on digikey too?

NXP's product page says it's a promo running to the end of the year.

That must be the fastest micro board at the price point?

And what's next!

And what's next!

Bit banged ethernet?

Bit banged ethernet?

Been done already, though maybe you can achieve better than half-duplex 10Base-T.

LOL. There's also a bit banged USB 1.0 low speed somewhere, I think.

That would be V-USB, and it's everywhere.
Have some bit-banged VGA, on an ATmega88 no less.

Bit-banged DVI next?

[GeorgeOfTheJungle]

That's sweet, but to call it VGA is a bit of a stretch For (fast) ethernet you need 125 MHz, VGA @ 640*480*60 => a 20 something MHz pixel clock, that poor 328p can't cope (neither speed nor RAM) thus the pixelation. USB low speed is 1.5 Mbit/s, that's why it's more doable.

Silicon Labs currently has a "Hands-On Virtual Bluetooth Workshop". You receive a free EFR32BG22 (BLE ready Cortex-M33) Thunderboard Kit (MCU + debugger + sensors). The online workshops session are scheduled in may.

I have difficulties coming up with an application where it would require such a high speed with no special peripherals, except the general communications...

IC have two audio I/O peripherals. If you still can't come-up with any application, then to mention just few: real-time audio beam forming, noise cancelling.

Silabs launched a development board based on the BGM220P (Bluetooth LE 5 SoC on a PCB module with antenna). I added it to the list.
Basic (no peripheral) but cheap ($9.99). And it has a JLink programmer onboard.
