Raspberry Pi Pico
Cheap, fast, and very good at precise timing.

(01)The instrument
Busier CPU, sloppier edges. The PIO block doesn't care what the cores are doing.
A simulation of how the part behaves — not a recording of mine. Bench photos go in the evidence below.

An RP2040
Two Arm Cortex-M0+ cores at up to 133 MHz and 264 KB of SRAM, on a board that costs less than lunch.

Little machines beside the cores
Next to the cores sit programmable I/O blocks — tiny state machines running their own instructions, so a timing-critical signal never waits for the CPU to catch up.

Exact pulses
Which means exact output: LED strips, protocols the chip doesn't speak natively, signals that have to land on the microsecond.
