Proteus-III-SPI Bluetooth Low Energy 5.1 Module

Proteus-III-SPI from Würth Elektronik is the Bluetooth Low Energy 5.1 module that is based on the Nordic Semiconductor nRF52840 chipset that offers significantly high performance with a payload of up to 964 bytes. The module offers four times the throughput of most Bluetooth low-energy modules. It allows a significantly higher data rate than the UART with 1.5 times the end-to-end data throughput.


The Proteus-III-SPI variant is ideal for applications in which no free UART interface is available, or if the data throughput of the UART interface is insufficient. Besides, this new SPI variant is more power-efficient compared to the ones already up on the market shelves.


The Bluetooth module measures a mere 8 x 12 x 2 mm and comes with an integrated antenna, encryption technology, and six configurable IO pins. Proteus-III-SPI offers a good alternative to the SPP (Serial Port Profile) mode for serial data transmission, which is extremely useful for industrial applications. The device includes a long-range mode. The Proteus-III-SPI is now available ex-stock without a minimum order quantity.
