BT860 Series Bluetooth Module
Overview
The BT86x series of UART HCI modules leverage the Cypress CYW20704 A2 chipset to provide exceptionally low power consumption with outstanding range for OEMs needing both Classic Bluetooth and Bluetooth Low Energy support. The Bluetooth 5 core specification shortens your development time and provides enhanced throughput, security and privacy.
The BT860 modules are ideal when designers need both performance and minimum size. For maximum flexibility in integration, they support a host UART interface, I2S and PCM audio interfaces, GPIO, and Cypress' GCI coexistence(2-Wire). The modules provide excellent RF performance and identical footprint options for integrated antenna or an external antenna via a trace pin.
These modules present a Bluetooth standard HCI interface with support for Linux / Android and Embedded Bluetooth software stacks for operating system backed devices. Additionally, Laird has partnered with SEARAN for support of their ultra small, flexible ‘dotstack’ platform for embedded Cortex M3 and M4 implementations.

Is it safe to run a Laird Connectivity Bluetooth module through a PCBA wash cycle?
In general, cleaning the populated modules is strongly discouraged. Residuals under the module cannot be easily removed with any cleaning process.
- Cleaning with water can lead to capillary effects where water is absorbed into the gap between the host board and the module. The combination of soldering flux residuals and encapsulated water could lead to short circuits between neighboring pads. Water could also damage any stickers or labels.
- Cleaning with alcohol or a similar organic solvent will likely flood soldering flux residuals into the RF shield, which is not accessible for post-washing inspection. The solvent could also damage any stickers or labels.
- Ultrasonic cleaning could damage the module permanently.
However, if water washing is required you will need to use deionized water. We do not recommend chemical cleaning and cannot guarantee it will not damage the modules. If you MUST clean PCB with chemicals it is recommended that you test on one board and then confirm the module still works after the process, prior to adding it to production, while understanding the above affects washing the populated PCBs can have on the module.
