# HBOX — Product Specification (Series 1 → Series 2)
|
||
|
||
> The HBOX as a product: what it is, its variants, interfaces, and target specs.
|
||
> Requirements live in [[01-Requirements/SRS|SRS]]; parts in
|
||
> [[03-Architecture-Hardware/BOM-master|BOM]]. **Series 1** = current
|
||
> module-based build (ASA case + Dupont wiring). **Series 2** = the production PCB target.
|
||
|
||
## 1. Overview
|
||
|
||
HBOX is a ruggedized, cabinet-housed **RTK GPS telemetry unit** for heavy port
|
||
equipment. It delivers **centimetre-class** position over 4G to the Helgen
|
||
backend, with an onboard **watchdog** that keeps the correction link alive
|
||
unattended. Sold as a **gabinete (cabinet) assembly**: an industrial IP67 cabinet
|
||
(power, protection, ignition isolation) + the internal HBOX (RTK + 4G + watchdog).
|
||
|
||
## 2. Variants
|
||
|
||
| Variant | Machine power | Cabinet supply → | Notes |
|
||
|---|---|---|---|
|
||
| 12 V | 12 Vdc | Mean Well DDR-60G-24 → 24 V | Tractoplana, Montacargas |
|
||
| **24 V** | 24 Vdc | DDR-60G-24 → 24 V | **dominant**: RTG, Reach Stacker, Empty Handler |
|
||
| 48 V | 48 Vdc | DDR-60L-24 → 24 V | — |
|
||
| 110 V | 110 Vac/dc | HDR-60-24 / Siemens → 24 V | + AC SPD + termomagnético |
|
||
| 230 V | 220 Vac | HDR-60-24 → 24 V | + Bussman fusing |
|
||
| **Base Station** | 110 Vac | — | Ardusimple AS-PRO-CORS (RTK source/NTRIP caster) |
|
||
|
||
Internal HBOX electronics are **identical across variants**; only the cabinet
|
||
power/protection stage changes with machine voltage.
|
||
|
||
## 3. Key specifications (targets)
|
||
|
||
| Parameter | Spec |
|
||
|---|---|
|
||
| GNSS | u-blox ZED-F9P, multi-band L1/L2, multi-constellation |
|
||
| Position accuracy | RTK fixed: ~1–2 cm + 1 ppm CEP (open sky, valid corrections) |
|
||
| Update rate | 1 Hz (active) / 30 s (idle/battery) |
|
||
| Corrections | NTRIP/RTCM3 over 4G LTE (ArduSimple 4G NTRIP Master) |
|
||
| Telemetry out | NMEA over UDP → retranslator → Wialon/Traccar → VERONICA |
|
||
| HBOX input | 24 Vdc (from cabinet) + isolated ignition |
|
||
| Internal 5 V | Mean Well SD-15B-05 (18–36 V→5 V, 3 A) |
|
||
| Backup power | PowerBoost 1000C + 18650 Li-ion 1S4P *(under review — see SRS FR-7)* |
|
||
| MCU / watchdog | STM32F411 Blackpill, firmware `blackpillrtkcode_v2` |
|
||
| HBOX↔cabinet | GX16-5 locking circular connector |
|
||
| Antennas | 1× multiband GNSS (SMA) + 2× LTE (AR1582) |
|
||
| Status | external LED (multi-pattern) + onboard LED + debug UART dashboard |
|
||
| Cabinet | Yetlebox P3901, ABS, **IP67**, 39×29×16 cm, DIN rail |
|
||
| Environmental (target) | −10…+75 °C internal; ≥2 G vibration *(to validate)*; coastal humidity |
|
||
| Enclosure (HBOX) | **Series 1: ASA (adequate)** → Series 2: ASA or metal / plate-mount |
|
||
|
||
## 4. Interfaces
|
||
|
||
- **GX16-5 (HBOX↔cabinet):** 24 V, GND, ignition, (spare ×2) — finalize pinout on
|
||
the schematic before PCB.
|
||
- **Antennas:** bulkhead SMA (GNSS) + 2× LTE via glands; torque + thread-lock.
|
||
- **SIM:** Telcel micro (Series 1, internal) → front-panel or MFF2 eSIM (Series 2).
|
||
- **Debug:** USB/UART ANSI dashboard (battery, fix, packets, temp, state).
|
||
|
||
## 5. Status indication (LED)
|
||
|
||
Boot (fast blink) · Running+RTK (solid) · Battery mode (heartbeat) · Searching/
|
||
degraded (slow blink) · LIMP/no-4G (SOS-ish double) · Power-cycling (strobe) ·
|
||
Sleep/critical (off). See firmware v2.
|
||
|
||
## 6. Model / SKU
|
||
|
||
`H-BOX Series1` (current) → `H-BOX Series2` (PCB). Each unit carries a Helgen
|
||
data label (modelo, serie, datos técnicos) + warning + input-voltage label.
|
||
|
||
## 7. Series 2 (production) deltas
|
||
|
||
ASA case retained (optional metal) · Dupont/hand-wire → PCB + locking connectors · discrete
|
||
watchdog → integrated load switch · battery decision · front-panel SIM ·
|
||
conduction cooling · documented assembly. See
|
||
[[03-Architecture-Hardware/hardware-respec-and-pcb-brief|hardware brief]].
|
||
|
||
## Open Questions
|
||
|
||
- [ ] Finalize GX16-5 pinout · battery strategy · enclosure material.
|
||
- [ ] Validate the 2 G vibration and IP67-after-mods claims for the datasheet.
