" Today, we’re launching our first microcontroller-class product: Raspberry Pi Pico. Priced at just $4, it is built on RP2040, a brand-new chip developed right here at Raspberry Pi. Whether you’re looking for a standalone board for deep-embedded development or a companion to your Raspberry Pi computer, or you’re taking your first steps with a microcontroller, this is the board for you.
It seems like every fruit company is making its own silicon these days, and we’re no exception. RP2040 builds on the lessons we’ve learned from using other microcontrollers in our products, from the Sense HAT to Raspberry Pi 400. It’s the result of many years of hard work by our in-house chip team.
We had three principal design goals for RP2040: high performance, particularly for integer workloads; flexible I/O, to allow us to talk to almost any external device; and of course, low cost, to eliminate barriers to entry. We ended up with an incredibly powerful little chip, cramming all this into a 7 × 7 mm QFN-56 package containing just two square millimetres of 40 nm silicon. RP2040 has:

now I don't know about you guys but I'm super stoked since this is basically raspberry pi meets arduino which is huge.
plus at that $4 price point it's great if you aren't buying the chips themselves rather than a module you can install into a socket or circuit.
on top of that the power cost is ridiculously tiny at 20 milleamps.
given how awesome the pi zero was when it came out for a similar crowd I look forward to what people end up making with these pico pi's.

- Dual-core Arm Cortex-M0+ @ 133MHz
- 264KB (remember kilobytes?) of on-chip RAM
- Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus
- DMA controller
- Interpolator and integer divider peripherals
- 30 GPIO pins, 4 of which can be used as analogue inputs
- 2 × UARTs, 2 × SPI controllers, and 2 × I2C controllers
- 16 × PWM channels
- 1 × USB 1.1 controller and PHY, with host and device support
- 8 × Raspberry Pi Programmable I/O (PIO) state machines
- USB mass-storage boot mode with UF2 support, for drag-and-drop programming
