# Glasgow Interface Explorer revC (1BitSquared)

> An FPGA-based digital interface tool that speaks UART, SPI, I²C and JTAG, reads and writes memory chips, and works as a logic analyzer.

- **Category:** Instruments
- **Availability:** Preorder
- **Price:** US$179, checked 2026-09-18
- **Good for:** Reverse-engineering a chip or dumping a memory device without dedicated hardware for each one.
- **You'll need:** A host computer running the Glasgow software.
- **Trade-off:** Steeper learning curve than a single-purpose adapter.

## Blueprint

**Open hardware.** Fully open hardware: KiCad schematic/PCB, Gerbers and BOM for every board revision (including shipping revC3) are in the official repo.

_Notes:_ Verified via gh api tree on GlasgowEmbedded/glasgow (0BSD, 2213 stars); repo carries every hardware revision from revA through revD1 with matching KiCad source and Gerber output folders, plus 3D-printable case files. Crowd Supply campaign page itself only links the GitHub org, not files directly.
