Radio Board H

Vers. 1.0, Dec. 11, 2019

The Radio Board H is developed to provide the communication for the rotating laser platform under usual

construction site conditions. It establishes communication using the standard BLE protocol with a

transmission power of +8 dBm. For the rotating laser platform it is 125 kbps for the communication with

the receiver tool otherwise 500 kbsp, 1 Mbps or 2 Mbps.

The Radio Board H is intended for Hilti internal use only. It is not for sale to third parties. Nevertheless,

any modification of the Radio Board H is prohibited. In case of modifications, the Radio Board H will lose

its certification.

The host product designer is responsible for compliance to all respective, relevant FCC rules. Additional

measurements and certifications are needed for the host product incorporating the Radio Board H. At

least module integration measurements shall be considered, e.g. with respect to RF exposure and radio

transmission.

The Radio Board H is tested against and compliant with FCC 15.247 / RSS 247 and the respective human

exposure requirements KDB 447498 / RSS102.

The Radio Board H can be used in a working temperature range from -20°C up to 60°C. The storage

temperature shall be between -40°C and 125°C.

The Radio Board H uses a Silicon Labs-Chips EFR32BG13P732F512GM48. The block diagram of the

chip is shown in the figure below.

The clock X1 provides a frequency of 38.4 MHz.

The antenna used on the board is an integral surface mounted antenna: the ceramic antenna W3000 from pulse. For BLE frequency band the max. antenna gain is 1.9dBi. The connections of the Radio Board H are the following  RST (Chip) Reset line  D (Digital) Ground  V1 Operating voltage (3.3V) Clear to send signal  CTS  RTS Request to send signal  TX Transmitted signal  RX Received signal For Canada, the minimum separation distance from a person’s body has been calculated to be 15 mm.
