nRF24LU1+ USB Dongle with Chip Antenna


This is a breakout of Nordic's latest USB-enabled IC, the nRF24LU1+. This IC starts with an 8051 microcontroller, and then adds an nRF24L01+ radio to it, plus a bunch of other peripherals, including AES encryption! The chip comes with Nordic's USB bootloader already installed. The ICs are the 16kB flash version.

Extremely Important Note:
Any code you write must be able to vector into the on-chip bootloader (flash address 0x7800), or else you will never be able to program the chip over USB again (until you re-flash the bootloader over SPI, at least). The example that is linked below shows how you could do this by adding a button on pin P0.0.

  • MCU: Enhanced 8-bit 8051-compatible microcontroller with 16 kB program flash memory, 2 kbytes SRAM, nRF24L01+ RF transceiver, 3 16-bit timers/counters, AES encryption/decryption co-processor, full-speed USB 2.0-compliant device controller, 6 GPIO, 32-bit multiplication-division unit, SPI, UART
  • On-chip bootloader is compatible with SDCC C compiler
  • On-board 300 mA 3.3V regulator
  • USB-A male connector so you can plug the board directly into a USB port
  • Power LED
  • On-board chip antenna (no external antenna needed!)
  • Up to 2Mbps on-air data rate
  • Air-compatible with nRF24L01, nRF2401A, nRF2402, nRF24E1, and nRF24E2
