OneBox
Lite
Board B1
Issued Apr 2026
Status Active
A rugged, wireless-first data-acquisition platform for industrial,
environmental, and field telemetry — built on a single compact board.
01 ── Overview
Acquire. Switch. Transmit.
The OneBox Lite is a self-contained edge node that sits between the physical
world and your network. Four protected analogue inputs, three high-current load
switches, and a full wireless stack live on one board — delivering connected
telemetry without the bulk of a PLC or the fragility of a development kit.
Engineered for long deployments in environments where cabling is expensive, power
is intermittent, and the last thing anyone wants is another dev-board in a plastic
enclosure held together with hope.

03 ── Connectivity
Wireless by design
Wi-Fi and Bluetooth 5 are primary, not an afterthought. An embedded wireless MCU
handles the radio stack and still leaves headroom for on-device filtering,
thresholding, and aggregation — so only the data that matters leaves the node.
When the network drops, logging continues to microSD. When it returns, buffered
records flush up the stack. RS-485 and USB-C cover legacy and local scenarios
without a separate gateway.
04 ── Signal Integrity
Built to survive the field
Every analogue input is fenced by a 33 V transient-voltage-suppression diode,
a Schottky clamp pair to the rails, and a first-order RC filter — all sitting
upstream of the silicon. Surges, inductive kickback, and ground-bounce events
are absorbed before they reach the ADC.
The USB front-end is ESD-protected to IEC 61000-4-2 levels. Load-switch MOSFETs
are rated well above typical industrial continuous current, keeping junction
temperatures low at duty.
05 ── Onboard Sensing
Context included
- Temperature & humidity — factory-calibrated, I²C.
- 3-axis accelerometer — vibration, tilt, shock & free-fall detection.
- User-programmable indicators — 8-channel LED driver for local status.
Every unit ships knowing where it is, what it's doing, and how it's feeling — no
external sensors required for baseline health telemetry.
06 ── Applications
Where it earns its keep
- Industrial process monitoring — pressures, flows, tank levels, valve states.
- Predictive maintenance — vibration signatures on motors, pumps, and gearboxes.
- Remote environmental logging — temperature, humidity, and custom 0–30 V inputs.
- Utilities & BMS — sub-metering, air-handling, and building telemetry.
- Asset & equipment telemetry — status, usage, and fault reporting over Wi-Fi or BLE.
07 ── Deployment
Connector-first integration
Two 10-position industrial Phoenix connectors carry power, loads, and analogue
inputs; a dedicated header exposes UART for commissioning. No soldered pigtails,
no ribbon-cable guesswork — the board drops into an enclosure and into a system.
