Wireless Modules
Bluetooth / BLE Modules
Low-power Bluetooth LE modules for battery-operated devices, with UART, SPI and I2C interfaces and optional custom firmware.
Overview
Bluetooth Low Energy is the default choice when a device has to run for months or years on a coin cell, transmit short packets and stay connected to a phone. We supply BLE modules built on mainstream Bluetooth 5.x SoC platforms, and we develop the firmware that runs on them.
Module selection usually comes down to four questions: how much current the application can afford in sleep mode, which peripherals the sensor or lock mechanism needs, whether the product must support over-the-air firmware updates, and how the antenna will be integrated into the enclosure. We work through these with you before a part is specified.
For customers who need more than a stock module, we design a custom BLE module or integrate the SoC directly onto the product PCB — including the RF layout, antenna matching network and pre-compliance testing.
Capabilities
What this covers
Ultra-low power operation
Sleep currents in the microamp range, with configurable advertising intervals and connection parameters to fit coin-cell budgets.
Flexible host interfaces
UART, SPI, I2C and GPIO options, with transparent transmission mode or a documented command set for the host MCU.
OTA firmware update
Over-the-air update paths for both the Bluetooth stack and application firmware, including fail-safe rollback.
Antenna and RF support
PCB trace antenna, ceramic chip antenna or external connector options, with matching network tuning and range validation.

Questions
Frequently asked
Can you supply a module with our own firmware pre-loaded?
Yes. We can program your firmware during production, or develop the application firmware for you if the product logic is not yet defined.
Do you provide the antenna design?
Yes. We design the PCB antenna or select a chip antenna, tune the matching network and validate range inside the actual enclosure.
What is a typical minimum order quantity?
Sample quantities are available for evaluation. Production MOQ depends on whether the module is a standard item or a custom design, and is confirmed in the quotation.
