All those RP2040 hacks are impressive (HDMI, etc) but also suggest that the RP2040 is just slightly underpowered for many practical applications. I hope some cheap RISC-V MCU unbound by ARM licensing constraints (with Atomic ops+SIMD, unlike Cortex-M0) comes soon.

Bit-banging Ethernet, now <i>that</i> is something I&#x27;d never thought to see.

It appears they&#x27;ve overclocked the RP2040 quite a bit without also increasing voltage. First time seeing that. Eg, slightly higher at 250Mhz some RP2040&#x27;s have been unstable without it: <a href="https:&#x2F;&#x2F;github.com&#x2F;pimoroni&#x2F;picosystem&#x2F;pull&#x2F;57">https:&#x2F;&#x2F;github.com&#x2F;pimoroni&#x2F;picosystem&#x2F;pull&#x2F;57</a>

It can probably be a bit simplified by using IPv6, as that avoids the IPv4 checksum.
