BT Smart Ready LogoBluetooth v4.0 Dual-Mode UART HCI Module

The BT830 series of UART HCI modules are a complement to Laird's original dual-mode Bluetooth v4.0 offerings (BT800 series), bringing support for Classic Bluetooth and Bluetooth Low Energy (BLE) in a tiny footprint.

Leveraging the market-leading CSR 8811 chipset, the BT830 series provides exceptionally low power consumption with outstanding range. Supporting the latest Bluetooth v4.0 Specification with EDR (Enhanced Data Rate), the Laird BT830 series enables OEMs to accelerate their development time for leveraging either Classic Bluetooth or Bluetooth Low Energy (BLE) into their operating system-based devices.

The BT830 has a footprint as small as 8.5 x 13 mm, yet output power at 7 dBm. This makes these modules ideal for applications where designers need both performance and minimum size. For maximum flexibility in systems integration, the modules are designed to support a UART interface plus GPIO and additionally I2S and PCM audio interfaces.

These modules present an HCI interface and have native support for Embedded Windows and Linux Bluetooth software stacks. All BT830 series devices are fully qualified by the Bluetooth SIG as a Hardware Controller Subsystem. This also allows designers to integrate their existing pre-approved Bluetooth Host and Profile subsystem stacks to gain a Bluetooth END product approval for their products.

The BT830 series is engineered to provide excellent RF performance with options for an integrated antenna or for an external antenna via a trace pin. Additionally, the modules have on-board band pass filters to further reduce the regulatory and testing requirements for OEMs, ensuring a hassle-free development cycle.

A fully featured, low-cost developer's kit is available for prototyping, debug, and integration testing of the BT830 series modules and further reduces risk and time in development cycles. Laird provides access to free technical support based in Europe, Asia and United States, as well as a large array of detailed Application Notes covering various topics to speed the OEM in testing, integrating and ultimately speeding time to market for BT830 based devices. In addition for BT830 customers using Windows CE and Windows Mobile, Laird has developed a new 'BooTpatch' driver for simple, copy and paste initialization of the BT830 configurations.

The BT830 is certified from compliance to various CE, FCC, Industry Canada and Bluetooth Special Interest Group. The grants, approvals, and formal test reports associated with these certifications may be leveraged by Laird Technologies customers to achieve their required device certifications. The degree to which customers can leverage these Laird Technologies Certification items is dependent upon the regulatory agency, industry body, and the type of end device.

If any additional information or guidance is required, please contact the wireless certifications group via email.


The BT830 Bluetooth® Module has been tested for compliance to various CE and ETSI standards and specifications:

These formal test reports may be leveraged by mobile and portable device vendors as part of their self declaration to obtain the CE mark required by members of the European Union. ETSI/CE rules differ from those of the FCC and IC in that there is no provision for a modular approval. All approvals and certifications must exist at the device level rather than the module (radio) level.

The BT830 is fully compliant with Annex IV procedures in article 10.5 of R&TTE directive 99/5/EC.

The BT830 is fully compliant with European Union Directive 2003/95/EC or Reduction of Hazardous Substances (RoHS) as per our Declaration of Compliance. Click to view the Statement of Compliance to EU WEEE Directive and RoHS Directive.


Laird has received the following FCC grants for the BT830:

The above grants are Modular Approvals. Specific limitations are indicated on each grant.

Test Reports:

Note: Laird test data may be leveraged by the device vendor to minimize the cost and time associated with the certification process.

Industry Canada

The BT830 is certified to the Industry Canada (IC) RSS-210 standard. Certification is based on FCC certification testing, using the same antennas and transmit power and covering the same frequency bands.  

Bluetooth SIG

The BT830 has received the Bluetooth SIG Qualification. For more information visit the Bluetooth Special Interest Group website, here.
