Certified Bluetooth Modules (KT1020 BLE)

Quick, seamless connectivity with lesser power consumption


KT1020 BLE Module is based on CSR1020 SoC from Qualcomm. Bluetooth modules can be designed into various types of electronic devices to handle a broad range of applications. Bluetooth low energy takes less time to make a connection than conventional Bluetooth wireless technology and consumes approximately 20 times less power than Bluetooth Basic Rate.
