Some key specs:
* <SoC>:
* name: RP2040. Custom designed by <Raspberry Pi Foundation>, likely the first they make themselves rather than using a <Broadcom> chip. But the design still is closed source, likely wouldn't be easy to open source due to the usage of closed proprietary IP like the <ARM (ISA)>
* dual core <ARM Cortex-M0+>
* frequency: 2 kHz to 133 MHz, 125 MHz by default
* memory: 264KB on-chip <SRAM>
* GPIO voltage: 3.3V
