Description

Jackrabbit is a RP2040-based 16-channel logic analyzer in a tiny 1.8" by 1.2" form factor. All digital inputs are buffered for compatibility with both 3V3 and 5V logic. Boot mode select and reset buttons are provided for convenience, and the ADC inputs and SWD pins are broken out. A USB-C connector is present for firmware updates and serial data.

Questions

How big is the Jackrabbit PCB?

It measures 45.1 × 29.2 mm and has 2 copper layers, 1.65 mm thick.

What parts does the Jackrabbit use?

64 parts, built around the RP2040, 74LVCH245AD, W25Q16JVSNIQ and MIC5319-3.3YD5. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Jackrabbit KiCad files?

From the rjhsun/jackrabbit repository on GitHub, at the commit this page was made from: the board is jackrabbit.kicad_pcb and its schematic jackrabbit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Jackrabbit design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
