AAE-1734 Remote Controller

The Aktakom AAE-1734 is a compact, versatile controller designed for monitoring and remote control of a wide range of equipment. Built around the reliable ESP-32-WROOM module, it combines wireless connectivity, flexible I/O options, and modular expandability, making it suitable for industrial automation, smart systems, and custom control applications. At its core, the controller supports WiFi (2.4 GHz), Bluetooth, and USB connectivity, enabling seamless integration with PCs, cloud platforms, and IoT environments.

Its command structure is based on JSON, which simplifies communication and allows easy implementation across popular programming languages such as C++, Python, Java, and LabVIEW. 

The AAE-1734 offers a robust set of input and output interfaces. It includes four digital inputs and four digital outputs, all with LED status indication. Three inputs are optimized for low-frequency signals, while the fourth can handle high-frequency signals up to 25 kHz, making it ideal for applications such as flow measurement or tachometry. Additional inputs allow connection of current sensors, AC/DC voltage measurement (0–36 V), and up to eight DS18B20 temperature sensors via a 1-Wire interface, with automatic device detection. 

Beyond standard I/O, the controller features four touch buttons, support for voice event notifications via a speech synthesizer, and expansion capabilities throughI2C-connected displays or sensors. 

It also supports external non-volatile memory and can be extended with additional hardware modules to increase channel capacity. 

Physically, the controller is available in multiple configurations: as a standalone PCB, a DIN rail–mountable version, or a fully enclosed unit with a transparent cover. Powered via USB Type-C (5V) or 12V input, and with a modest consumption of around 500 mA, it is well-suited for both bench-top and field installations. 

Overall, the Aktakom AAE-1734 stands out as a flexible, developer-friendly controller that bridges embedded hardware and modern IoT systems with ease.

The Aktakom AAE-1734 controller is based on a ready-made ESP-32-WROOM module, which can be installed separately and easily replaced.
The controller is available in multiple configurations (Axx versions), which differ in installed electronic components and board layout options.
The command system is implemented using JSON format commands, which are easy to read and interpret by users and are supported by virtually all programming languages (C++, Python, Java, LabVIEW, etc.).
