HM-BT220X is a BLE data transmission module, based on a BLE 5.2 SoC chip (ARM Cortex-M33 32-bit processor, up to 76.8MHz working frequency), embedded with a 2.4GHz transceiver, equipped with an
on-board PCB antenna. The module communicates with an external MCU to quickly set up wireless connection and data transmission between BLE slave devices and BLE master devices (such as mobile phones and tablets). The external MCU has a low resource occupation and the development process is very easy.
The Bluetooth technology manages the communication channel of the wireless part. The Bluetooth modules can transmit and receives the data wirelessly by using two devices. The Bluetooth module can receive and transmits the data from a host system with the help of the host controller interface (HCI).
Note: Product image may vary from the actual product.
