Access Control for Developers   


Build and deploy your own Access Control system. Programmable hardware, packed with features.
ESP32 + NFC = ❤️

Access Pro

The single board solution built around the ESP32 microcontroller, for all your access control needs. 

  • Access Control
    Read NFC tags to open doors with electric strikes (integrated 12V relay) or motors (toggle GND). A second board can be used as an antenna for enhanced security.
  • Garage Door Opener
    BLE or WiFi can be used to remotely to trigger an external relay for higher voltages. Use a magnetic contact switch to monitor when the garage was opened.
  • Time-Tracking
    Use the integrated NFC antenna and real time clock to check in or out by triggering an API call to a remote server. 

And more: monitor temperature and humidity, control lights or heating depending on weather or time of day, use for irrigation, trigger audible alerts, write NFC tags, attach fingerprint reader etc.

The mission

To create easily programmable hardware, capable of a wide range of real-world applications.

Reliable  Hardware

Designed for operating temperatures between -20℃ and 80℃ with only high quality components throughout.

No logs, zero telemetry

You control the entire stack, no network calls to any servers, no exception. You can create an offline-only device. It's your choice.

100% self-funded

Access Pro was built and deployed out of internal necessity. All software is created in-house too.

Open for coding.

Use Arduino IDE, ESP-IDF, platformIO, Visual Studio Code and more to program Access Pro via USB.

 Attach peripherals: magnetic contact switches, 240V relays, sensors, external antennas, link two boards with a bus, etc.

 Create an app to communicate via BLE and open doors (or garages) wirelessly.

 Use many different NFC Tags: stickers, cards, key-fobs and wristbands; Anything with MFRC522 compatibility.

Get Access Pro

We're currently looking for a distributor to help us get the boards in the hands of as many interested developers as possible. If you are able to purchase through a business (B2B), we're able to send you Access Pro boards - please send us an email.
