"30 configurabe I/O pins, woah! ...On this teeny, tiny, little thing!"


"Configurable también para otros protocolos como ANT o propietario, este SoM Bluetooth para la IoT ofrece un dispositivo completamente integrado que no requiere de ningún otro componente en la placa, ahorrando así espacio y costes en los desarrollos."

The arrival of Bluetooth 5 was a significant leap forward for the IoT developer community, especially with its new Bluetooth Mesh functionality, which connects more devices and more sensors. Nearly four billion devices are expected to be shipped with Bluetooth technology in 2018. Bluetooth is driving innovation and creating new markets for wireless audio, wearables, tracking assets, building automation, lighting, sensor farms, etc…

With a design based on the Nordic nRF52832 SoC, combining a low power 64 MHz ARM Cortex-M4F and the 2.4 GHz radio in a single chip, the BLYST Nano SoM (System on Module) is the perfect way to catch this new Bluetooth IoT wave driven by both Bluetooth 5 and Bluetooth Mesh.

  • The BLYST Nano is low power and small enough, at 10 x 7 x 1.6 mm, for wearable and sensor applications.
  • With 30 programmable I/O pins, it's versatile enough to fit any control and automation application.
  • With a hardware floating point unit, algorithms can be directly implemented on the device, allowing more realtime sensor fusion processing.
  • It is a complete System on Module with all required components (crystals, coils, DC/DC, etc.) built-in and ready to use. So you don't need to take up more board space with add-on components needed to support a given module.

BLYST Nano Module Features

  • Built-in ceramic antenna
  • Built-in coils for low power DC/DC mode
  • Built-in 32 MHz & 32.768 MHz crystal for low power
  • Dimensions: 10 x 7 x 1.6 mm
  • No extra PCB spaces or any external components required on users' application board
  • All I/O pins of the nRF52832 are exposed to pads around the edges of the module to take full advantage of the nRF52832 and for easy assembly without compromise
  • FCC & CE certified

BLYST Nano Open Source Software Development Resources

There are lots of software developement resources available for the nRF52832. It is well supported by the open source community, from beginning Arduino users to more advanced progammers. The Micropython port is also available for the BLYST Nano based boards.

nRF52832 Features

  • Single chip, highly flexible, 2.4 GHz multi-protocol SoC
  • 32-bit ARM Cortex-M4F Processor
  • 1.7 V to 3.6 V operation
  • 512 kB flash + 64 kB RAM
  • Supports concurrent Bluetooth low energy/ANT protocol operation
  • On-chip NFC tag for Out-of-Band (OOB) pairing
  • Up to +4 dBm output power
  • -96 dBm sensitivity, Bluetooth Low Energy (BLE)
  • Thread safe and run-time protected
  • Event driven API
  • On air compatible with nRF24L and nRF24AP series
  • 2 data rates (2 Mbps/1 Mbps)
  • PPI - maximum flexibility for power-efficient applications and code simplification
  • Automated power management system with automatic power management of each peripheral
  • Configurable I/O mapping for analog and digital I/O

Processing Power

The nRF52832 incorporates a powerful Cortex-M4F processor enabling the most demanding applications with complex arithmetic requirements to be realized in a single chip solution. The IC supports DSP instructions, a Floating Point Unit (FPU), single-cycle multiply and accumulate, and hardware divide for energy-efficient processing of computationally complex operations.

Multiprotocol Radio

The 2.4 GHz radio supports multiple protocols including Bluetooth Low Energy, ANT, and 2.4 GHz proprietary. The radio has high definition RSSI (Received Signal Strength Indication) and highly automated functionality, including EasyDMA for direct memory access during packet send and retrieve. Nordic provides protocol stacks for Bluetooth Low Energy. ANT protocol stacks are available directly from ANT.

Power Efficiency

The nRF52832 SoC is an extremely power efficient device that can run from a supply that provides 1.7 V to 3.6 V. All individual peripherals and clocks can flexibly power down when not required for task operation, thus minimizing power consumption. The IC has a comprehensive system of automated and adaptive power management features. These features range across the entire IC’s operation, from power supply switching to peripheral bus/EasyDMA memory management, to automated shut down of all but the absolute essential peripherals required to perform a task.

On-chip NFC Tag

NFC™-A tag support is included on-chip. Out-of-Band (OOB) pairing using NFC simplifies the process of authenticated pairing between two Bluetooth devices by exchanging authentication information over an NFC link.

Sensor Board

The Sensor Board pledge level

The Sensor Board is a 34 mm diameter round board pre-assembled with a BLYST Nano module. It has a suite of sensors on-board including: temperature, humidity, pressure, air quality, and motion sensing. And it has all the components you’d need to run a stand-alone sensor node with data logging.
