Key Features:

Long Range connectivity up to 1 KM with Bluetooth Mesh

The MeshTek H52 High Power Module includes an integrated antenna and power amplifier that extends the open air range of the module up to 120 meters (+390 feet).  Each module can be meshed with another up to 12 hops, enabling much larger spaces and distances to be covered compared to traditional Bluetooth devices.  With the meshing enabled, you can send messages over 1Km by meshing the devices together over multiple hops.

FCC/IC, CE and BT SIG Certified

Bring your products to market quickly by leveraging the key market certifications needed and avoid losing time and money in the certification process.   The MeshTek H52 module has the key certifications you need, and can be upgraded to accommodate new standards and software to keep your devices competitive.

Real Time Clock

Each MeshTek H52 High Power Module features a real time clock for built in automation capacity.   Schedule your devices to turn on and off at specific times, as well as change functions.   For lighting applications, you can also utilize ilumi Solutions patented technology that will maintain schedules and settings, enabling seamless recovery from power outages.

512kB Flash /64kB RAM

With a large 512K flash and 64kB RAM memory, the MeshTek H52 module has more than enough memory to store code, meshing instructions, and cloud connectivity applications needed for IoT devices.

26 Unique GPIO’s

Each MeshTek H52 module includes 26 GPIO’s that can be configured as a UART, SPI, I2C, or  Analog Inputs.  In addition the module will also support 4 PWM channels for smart lighting and other LED applications.

Simple integration using ilumi Solutions Development Kit

Design, configure, and test your Bluetooth mesh product features faster than ever using the ilumi Solutions Development Kit (Link) and mini board (sold separately).  This kit enables you to test with multiple power supplies, such as USB and Battery, as well as easy connections to programmer boards and other devices.  These kits come with sample iOS and Android API software
