11 CE REGULATORY
The BL652-SA/BL652-SC have been tested for compliance with relevant standards for the EU market. The BL652-
SC module was tested with a 2.21 dBi antenna. The OEM can operate the BL652-SC module with any other type
of antenna but must ensure that the gain does not exceed 2.21 dBi to maintain the Laird approval.
The OEM should consult with a qualified test house before entering their device into an EU member country to
make sure all regulatory requirements have been met for their complete device.
Reference the Declaration of Conformities listed below for a full list of the standards that the modules were
tested to. Test reports are available upon request.
Antenna Information
The antennas listed below were tested for use with the BL652. For CE mark countries, the OEM is free to use any
manufacturer’s antenna and type of antenna as long as the gain is less than or equal to the highest gain approved
for use (2.21dBi) Contact a Laird representative for more information regarding adding antennas.

Note: The BL652 module internal BLE chipset IC pins are rated 4 kV (ESD HBM). ESD can find its way through
the external JTAG connector (if used on the customers design), if discharge is applied directly.
Customer should ensure adequate protection against ESD on their end product design (using the
BL652 module) to meet relevant ESD standard (for CE, this is EN301-489).
