# BOOSTXL-TMP107 tscircuit reconstruction
This project reconstructs the Texas Instruments BOOSTXL-TMP107 BoosterPack in tscircuit. The electrical design follows TI's MHR035 Rev A schematic in the official BOOSTXL-TMP107 user guide. The board includes the LaunchPad headers, selectable UART transmit path, main TMP107, and two breakaway TMP107 sensor nodes.
The complete board is authored directly in `index.circuit.tsx`. Non-passive populated parts are local JLCPCB imports; resistors and capacitors use native tscircuit components with explicit manufacturer and JLCPCB part numbers.
## Local checks
```sh
bun install
bun run release-check
```
Individual commands:
```sh
bun run typecheck
bun run build
bun run verify
bun run check:shorts
bun run snapshot:update
```
## Source authority and current limits
- Electrical values, part numbers, pin connections, and UART mode selection come from TI's official schematic.
- The board dimensions, header placement, and breakaway layout are reconstructed from TI's board photography and the standard 2.54 mm BoosterPack grid.
- TI currently exposes the user guide and firmware on the product page, but not the original editable CAD/Gerber package. Therefore this project is a faithful reconstruction, not a byte-for-byte copy of TI's PCB files.
- Passing the automated checks proves internal consistency and absence of detected copper shorts. It does not replace a prototype assembly and bench test before production quantity.
See `reference/README.md` for primary sources and `docs/design-verification.md` for the cross-check record.
