Our PCB brings the user many benefits, when installed in existing fittings and also at the manufacturing stage..

Open protocol – sits on top of any platform


Depending on requirements, further services can be 'unlocked' without extra installation


A number of products rolled into one solution


Significantly less failure points and limitations than other systems


No specific software engineer required for maintenance


Encrypted data with Bespoke Connectivity


Unique PCB gives full flexibility to work with manufacturers

Promptus Ltd provides manufacturers with our trademarked PCB in its basic format, which allows them to produce their own product with our systems pre-installed.

Features of Remo-tech All in one solution

  • Low power. Designed to operate on battery power, to be "always-on", maintain time & location, while typically drawing less than ~26µA in low power consumption.

  • MCU-agnostic. Support any MCU or single-board computer to work alongside Remo-tech.

  • Global. With both narrowband and wideband modems tailored globally, Remo-tech can connect in any location with an added external sim coverage solution.

  • Hassle-free. No SIM or carrier subscription is required. Includes 10-years of global cellular service with 500MB of data as default with an option to choose your preferred ISP (more data options available upon request). 

  • Secure. Integrated with 256-bit encryption to upload the data to the cloud, added device unique tokens and each device secured with a password.

  • Power-conscious. Integration with any external antenna of your choice with GPS and GNSS antenna connectivity for real time and location at all times. Includes future proofing approach to protect any loss of connectivity. With a local data storage option that ensures data will be uploaded once connectivity is restored.

  • Connected. Provides built in firmware connectivity. Works in any building application from 1 store building to enterprise using GSM, Wi-fi, BT at the same time to match individual client requests without the need to reprogramme everything as out of the box solution.

  • Encrypted. Secures transactions without any provisioning challenges, using encrypted "off the internet" communication.

  • Efficient. Battery-powered cellular without the complexity of managing modems, connections, queues, or storage.

  • Integrated. Can be integrated directly from Remo-tech hardware to any third-party platform without any subscription cost using protocols as MQTT, TCP.IP, HTTPs or our fully build Vigilate cloud-based portal as default.

  • Built for data. Data routing using our Vigilate platform is also available with simple "no code/low code" visual data stream analysis through the portal, or host and integrate Vigilate portal functionality into your own app (OSS).

Power Information

Remo-tech Base and Simcarrier can be powered by connecting directly to the Micro-USB port.

For alternative installations, several alternate power options are available:

  • Attaching a LiPo battery.

The LiPo battery must be a single-cell 3.7V battery with a 2-pin JST PH connector.

  • Attaching a solar cell (must be accompanied by LiPo).

The solar charging circuit is designed for use with a 4.5-7V solar panel.

  • Applying 2.5-5.5VDC to the V+ pin.

Commonly provided via DC power supply or non-rechargeable battery.

Remo-Tech Base (shown below)

Remo-tech base is ESP32-E chip of the master control board. Aimed at Internet of Things, the SOC combines Wi-Fi, Bluetooth and MCU. The master control board uses a ultra-low power consumption external hardware design (an actual measurement of the electricity current under low power consumption mode is 10 μA), supporting onboard lithium battery charging so is ideal for low power consumption projects.

Remo-Tech Base has 30 pre-soldered male headers, 3 pin outdoor temperature connectors and 14 pin connections to stack on top and control Simcarrier with GSM Quectel card.

The Promptus PCB was developed through years of strenuous R&D. We are proud to have the most versatile PCB on the market, which has allowed us to fit our devices into any existing light fitting but also supply the PCB to manufacturers to use as they wish.
