Four small green circuit boards with chips and connectors

KEHIPI

KEHIPI 4PCS NRF52840 Development Board 64MHz 1MB 256KB

SKU CH-8ZF5-ATYBZ

Four NRF52840 development boards with ARM Cortex-M4F at 64MHz, 1MB flash and 256KB RAM for wireless projects

  • ARM Cortex-M4F at 64MHz with 1MB flash and 256KB RAM
  • Four boards per pack for multi-node prototyping
  • Compatible with Nice!Nano V2.0 footprint
  • 7V lithium interface with software LED cut-off
  • Standby current down to 1mA when LED disabled

Four NRF52840 boards for wireless IoT projects

This pack supplies four NRF52840 development boards built around an ARM Cortex-M4F core running at 64MHz with 1MB flash and 256KB RAM. Each board includes Bluetooth connectivity, a 3.7V lithium battery interface and a software-controlled LED power switch. They are compatible with the Nice!Nano V2.0 form factor and suited for hobbyists and professionals developing low-power wireless modules.

Check power and firmware toolchain before ordering

Verify that your project can supply 3.7V to the battery connector and that your development environment supports the ARM Cortex-M4F architecture. The onboard software switch can cut LED power to reach a 1mA standby current, so confirm your firmware can control this feature. Ensure you have the necessary programmers and SDKs for the NRF52840 chip.

Replaces single-board prototypes

The four-board pack replaces individual prototype boards, letting you build mesh networks or multi-node testbeds without sourcing separate units. It upgrades from the older NRF5280 by adding the Cortex-M4F core, larger flash and RAM, and integrated charging management. The jump is worth it when you need concurrent Bluetooth nodes, lower standby current or the Nice!Nano V2.0 pinout for keyboard firmware.

Questions about this item

Does the pack of four boards include batteries or cables, or do I need to source them separately?

The four boards are supplied without batteries or cables; each board has a 3.7V lithium battery interface so you add your own cell and USB lead.

All four units appear identical — is there any difference in flash or RAM between them?

Every board uses the same NRF52840 chip with 1MB flash and 256KB RAM, so there is no capacity choice to make.

What does the 64MHz Cortex-M4F speed mean for real-time Bluetooth tasks?

The 64MHz ARM Cortex-M4F core handles 2.4GHz Bluetooth protocol stacks and real-time sensor processing with headroom for custom firmware.
