Raspberry Pi Pico and RP2040 Microcontroller
Some high level info on the Pico [1]:<p><pre><code>  - New RP2040 microcontroller with 2M Flash
  - Micro-USB B port for power and data (and for reprogramming the Flash)
  - 40 pin 21x51 &#x27;DIP&#x27; style 1mm thick PCB with 0.1&quot; through-hole pins also with edge castellations
   - Exposes 26 multi-function 3.3V General Purpose I&#x2F;O (GPIO) 
   - 23 GPIO are digital-only and 3 are ADC capable
   - Can be surface mounted as a module
  - 3-pin ARM Serial Wire Debug (SWD) port
  - The power supply achitecture is pretty simple (you can power the unit from micro-USB, external supplies or batteries)
  - Buy price is $USD 4.00
  - MicroPython &amp; C++ SDK
  - Pinout Diagram: https:&#x2F;&#x2F;files.littlebird.com.au&#x2F;Shared-Image-2021-01-21-17-39-47-GVzHd.png
  - When using MicroPython, the programming model is similar to other boards where you have to unplug and plug back in the board. I hope this is ok on the Micro-USB port.
  - The isn&#x27;t currently a version with header pins, so you&#x27;ll have to add your own, or get one from a Reseller who will mode them for you (like this one [2]).

The burried the lede is that Raspberry Pi have created their own silicon (just like that other fruit company).
They call their Microcontroller the &quot;RP2040&quot;:<p>It boasts some impressive specs:<p><pre><code>  - Dual-core cortex M0+ at up to 133MHz
  - On-chip PLL allows variable core frequency
  - 264K multi-bank high performance SRAM
  - External Quad-SPI Flash with eXecute In Place (XIP)
