## Blueprint

**Closed design.** InfiShark publishes only an open-source host-side CLI/SDK and docs; no schematic, PCB, or BOM for the BLEShark Nano board itself is published.

### Source repositories

- [infishark/infishark](https://github.com/infishark/infishark) — sdk, GPL-3.0, ★17
- [infishark/nano-docs](https://github.com/infishark/nano-docs) — docs, ★22

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| ESP32-C3 | MCU (RISC-V, Wi-Fi + BLE 5.0) | https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf |

_Notes:_ Checked infishark.com/products/bleshark-nano, docs.infishark.com/docs/sdk, and every repo in the infishark GitHub account (infishark, nano-docs, airhorn, compliance) — the infishark CLI (GPLv3) talks to the device over USB but is host tooling, not hardware source; device firmware and PCB design were not found published anywhere.

| Charge indicator | Red LED indicates charging; off means complete when connected with switch ON |
| Current setup | Choose Wi-Fi and enter its password on the device; setup then downloads firmware |
| Older shipped setup | Some units use a phone/laptop captive portal instead; either flow is documented |
| Multiple-device setup | Optional Bluetooth pairing shares Wi-Fi credentials and Shiver identities among selected Nanos |

### Firmware & recovery

| | |
|---|---|
| OTA behavior | On-boot Wi-Fi check prompts before updating; checks are enabled by default and can be disabled |
| Web recovery | Official web flasher installs setup firmware only; full releases arrive over Wi-Fi |

| Documented SDK release | v1.1.0, July 14, 2026, adds the USB host control plane |
| Infrared files | v1.1.0 host tooling reads/writes Flipper-style .ir files and transfers remote slots |

### Shiver & computer use

| | |
|---|---|
| Shiver minimum | Two or more paired Nanos share state, files and commands without a phone/computer |
| Pairing | Pair over Bluetooth, then switch to the mesh; current firmware is recommended on every node |
| Shared-radio limit | Turn Shiver off for Bad-BT, Mini Keypad or Scroller persistent-Bluetooth functions |
| Host tools | Open-source Rust SDK/CLI controls compatible firmware over USB serial; standalone menus remain available |
| Host requirement | Computer with USB plus firmware containing the USB control plane |
| Linux-only features | Wi-Fi adapter mode and BLE HID bridge currently require Linux; other serial features vary by host |
