The HM-BT4501 from HopeRF is a wireless data pass-through module based on a CMT4501 low-power Bluetooth 5.0 chip. By connecting with a microcontroller, it can be used to realise a connection and data communication between the module and Bluetooth devices such as smartphones and tablets.
The module aims to simplify development without any experience in Bluetooth stack applications, and supports AT instructions for various software, connection and power management functions. It operates from a working voltage in the range of 1,8 V to 3,6 V, across a temperature range of -40°C to 125°C. It supports transmitter power levels between -20 dBm and +8 dBm, and has a receiver sensitivity of 97 dBm.
