An ultra-low-power Bluetooth Low Energy 5.0 module from Panasonic that enables the transmission of large amounts of data in Internet of Things (IoT), beacon, and mesh network applications is available at Mouser Electronics. The module is based on the Toshiba TC35680 single-chip controller, which provides an Arm Cortex-M0 processor core with Serial Wire Debug (SWD) interface and 128 Kbytes of flash memory.

It integrates standard Bluetooth Low Energy profiles in addition to Serial Port Profile (SPP), and offers three types of operation: host mode, AT command mode (coming soon), and a stand-alone mode that eliminates the need for an external processor.

Bluetooth 5.0 features enable a high symbol rate of 2Mbits per second (Mbps) using the high-speed 2M PHY or a significantly longer range using the Low Energy-coded PHY at 500 Kbits per second (Kbps) or 125 Kbps.

A high output power of up to 8 dBm and the sensitivity of the TC35680 (-105dBm at 125Kbps) in combination with the Low Energy coded PHY make the module very attractive in applications where a long range is required.

The module offers 18 general-purpose inputs/outputs (GPIOs), shared by two I²C, SPI, and UART interfaces; four PWM outputs; and five analogue-to-digital converters (ADCs).

Housed in a compact 15.6 × 8.7 × 1.9 m package, the device’s low current consumption provides an ideal solution for battery-powered applications.

It is also pinout compatible with the PAN1760A and PAN1026A Bluetooth modules, enabling designers to easily migrate previously developed software.

Support comes in the shape of the PAN1762 Evaluation Kit which features two USB dongles for developing, running, and debugging code, while breakout headers allow developers to connect sensors and devices for prototyping.
