Prawnblaster

The Prawnblaster is a microcontroller-based pseudoclock based on the Raspberry Pi Pico.

This device supports up to 4 independent pseudoclock outputs, with up to 30,000 instructions distributed among the outputs. It has a minimum resolution of 1 clock cycles and a minimum pulse width of 5 clock cycles. Using the default internal 100 MHz clock, this represents a 10 ns timing resolution and a 50 ns minimum pulse width. It also supports the ability to time the duration of waits internally.

For arbitrary digital trigger outputs, see the PrawnDO companion device.

The source code and pre-built firmware binaries are available from our github repository.
