# High Boy (High Code)

> A multitool project proposing integrated Wi-Fi, LoRa, sub-GHz and RFID interfaces.

- **Category:** Multitools
- **Availability:** In development
- **Good for:** Follow a proposed handheld with several radio types.
- **You'll need:** Final hardware, firmware and delivery information.
- **Trade-off:** The maker page lists inconsistent battery capacities.
- **Page:** https://gadgets.sh/devices/high-boy/

## Blueprint

**Open hardware.** High Code publishes EasyEDA PCB source + full schematics (PDF) and 3D-printable case STLs for the REV 2.2 MVP board under an open license.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| ESP32-S3 | MCU (published Rev 2.2 board) | https://www.espressif.com/sites/default/files/documentation/esp32-s3_datasheet_en.pdf |
| TI CC1101 | Sub-GHz transceiver | https://www.ti.com/lit/ds/symlink/cc1101.pdf |
| NXP PN7150 | NFC reader/writer | https://www.nxp.com/products/PN7150 |

_Notes:_ IMPORTANT for rebuilders: the Highboy_PCB repo README states these files are Rev 2.2, a validated MVP prototype built around a single ESP32-S3 — NOT the final production design. The maker's own site (highboy.com.br, checked 2026-09-27) describes a different, not-yet-published dual-MCU final architecture (ESP32-P4 app processor + ESP32-C5 comms processor); those final schematics were not found published anywhere. Firmware (TentacleOS) is also open on GitHub but omitted here per instructions to exclude firmware.
