Atmega328P Arduino Plus Nrf24l01+ Board, Nrf24Duino R1.6

Description

• The Nrf24Duino is an Arduino-based board featuring an attached 2.4G nrf24l01+ wireless transceiver. It is a low-cost solution designed for short-distance wireless communication.
• In open areas, the range can reach 500 meters, but in indoor environments, it is typically limited to 10-50 meters. The Nrf24l01 has poor capability for transmitting through walls.

Features:

• On-board control IC: Atmega328, pre-flashed with the Arduino bootloader and RF24 (getstarted) sketch .
• On-board 8M-bit (previously 4M-bit) Winbond SPI Flash memory, compatible with the SPI flash library.
• On-board programming LED D9. No power LED.
• Pre-soldered NRF24L01 module; pin headers are not soldered. Find more information about this Nrf24l01 board here.

R1.6 New Features:

• Bootloader firmware updated to Arduino Pro-mini 3V3/8M for low-power operation.
• Power pins are "3V3, GND, VIN, 3V3". The VIN pin can be disconnected, supporting the use of boost or buck boards, for example our mini boost board. Using two AA batteries, the board continues to work even when power drains down to 1.8V.
• The D9 programming LED can be disconnected via a jumper.
• Optimized for NRF24L01+ transmission range; range tests can be found here.
• The NRF IRQ interrupt pin is NOT connected to the Arduino D2 interrupt pin. During testing, it appeared to influence the range, so it was omitted in this version. The board works perfectly, but this specific function cannot be used.

Specifications:

• Total board size: 23x37mm (previously 4.5×2.5cm), with a layout similar to the Arduino Pro Mini.

Note:

• Each purchase is for one board only.
