The Panasonic PAN1762 Series RF module, now available from Mouser, is an ultra-low-power Bluetooth Low Energy 5.0 module allowing the transmission of large amounts of data in connectionless environments, offering a compact solution for IoT, beacon, and mesh network applications.

The module is based on the Toshiba TC35680 single-chip controller, which offers an Arm Cortex-M0 processor core with SWD interface and 128Kbytes of flash memory. The module combines standard Bluetooth Low Energy profiles as well as SPP and provides three types of operation: host mode, AT command mode (coming soon), and a stand-alone mode that excludes the need for an external processor.

The module’s Bluetooth 5.0 features allow a high symbol rate of 2Mbps using the high-speed 2M PHY or a particularly longer range using the Low Energy-coded PHY at 500Kbps or 125Kbps. A high output power of up to 8dBm and the excellent sensitivity of the TC35680 (-105dBm at 125Kbps) together with the Low Energy coded PHY make the module very attractive in applications where a long range is needed.

The module provides 18 GPIOs, shared by two I<sup>2</sup>C, SPI, and UART interfaces; four PWM outputs; and five ADCs. Housed in a compact 15.6mm x 8.7mm x 1.9mm package, the device’s low current consumption offers an excellent solution for battery-powered applications. The module is also pinout compatible with the PAN1760A and PAN1026A Bluetooth modules, allowing designers to simply migrate earlier developed software.

The module is supported by the PAN1762 Evaluation Kit. The all-inclusive kit offers two USB dongles for running, developing, and debugging code, while breakout headers enable developers to connect sensors and devices for prototyping.
