Bill of materials (tracking hardware)
Street prices incl. VAT in CZK, checked Jul 2026 (≈23 CZK/USD). v1 launch: UWB baseline only (~89k). Retro bands on wands ~50 CZK each (optional). v2 optical additive after bench gates.
Wand (per unit)
| Component | Qty | CZK |
|---|---|---|
| Prokyber Esp32-C6-Bug module — integrates TP4057 charger, DW01 protect, 3V3 LDO and USB-C | 1 | 699 |
| DWM3001C UWB module (~$42 @ qty 25–99; sub-1,000 only at qty 100+) | 1 | 1,180 |
| BMI160 IMU | 1 | 88 |
| WS2812 RGB LED | 1 | 15 |
| Laser diode (Class 1*) | 1 | 18 |
| Li-ion 18650 (Samsung 30Q) — charging is on the C6-Bug, no separate TP4056 | 1 | 125 |
| Custom PCB | 1 | 150 |
| Enclosure / body | 1 | 160 |
| Button, passives, connectors | 1 | 60 |
| Wand subtotal (street ~2,495 · w/ assembly margin) | ~2,750 | |
| Retroreflective tape bands (Scotchlite-class) optical v2 | 1 | ~50 |
* Tip laser is Class 1 (KY-008 form-factor, attenuated via current-limit / diffuser); document IEC 60825 / EN 50689 on the finished wand. Tip forward LED is RGB VFX, not IR. The DWM3001C (1,180) and Esp32-C6-Bug (699) are 68% of the wand's part cost, so fleet size is the lever if tracking spend must come down. The haptic coin motor (GPIO 6, firmware TBD) is not yet costed — a tens-of-CZK part that does not move the totals.

Where to buy — parts & systems (Czech eshops)
A concrete shopping list for the whole stack: the wand, the UWB anchors, the smart LED obstacles, and the arena systems (network, audio, lighting/DMX, optical cameras, compute). Prices are incl. VAT in CZK, checked Jul 2026; rows marked approx are typical street prices (exact SKU varies), and fleet/bulk buys come down further. Czech retailers are preferred; a few specialist parts ship from EU/PL distributors where there's no CZ stock.

| DWM3001C UWB module | Mouser / RFMW EU | ~1,180 |
| ≈ per anchor | ~1,580 | |
| Anchor array (×12) | ~19,000 |
Same UART-to-DWM3001C design as the wand — only the firmware and the ceiling mount differ. Power is USB 5 V into the DevKit (power bank or wall wart); there is no 12 V buck on the node.
Smart obstacle / LED block (per unit) · ~15 needed
| Part | Role | Where | CZK |
|---|---|---|---|
| ESP32-C6 DevKit (WLED) | LED brain | LaskaKit | 398 |

| Logic level shifter + powerCON connector | data + power link | LaskaKit + Neutrik NAC3FXXA | ~310 |
| ≈ per block (excl. strip length) | ~2,500–3,500 |
~250 m of WS2815 across ~15 blocks dominates the lighting spend (~99k CZK total incl. profiles, PSUs, floor wiring). Strip price varies with density (30 vs 60 LED/m) and IP rating.
