Introduction

The ACN52840 is a fully integrated, ultra-low power, Bluetooth 5 low energy module in a small form factor which features the advanced Nordic Semiconductor nRF52840 SoC. Its capabilities are tailored for the upcoming demands of sophisticated IoT devices where small size, low power, application performance and radio-range are essential. Unlike many competitors it features a maker-friendly PCB scale package which allows a fast and easy integration without sacrificing access to its advanced peripherals and capabilities. The ACN52840 features a large number of GPIOs including NFC and USB connectivity. Thanks to an on-board antenna and Bluetooth 5 its RF performance is excellent, allowing up to 1000m range on open field. To provide quick access to the programming interface of the SoC, the module also features a Tag-Connect connector.
