RF~Nano for Nano Micro USB Nano Board AT328P QFN32 5V 16M CH340 Integrate NRF24L01+2.4G wireless

Product descrtion:

The NRF24LO1+ is integrated on the RF-NANO board, which es it have unlimited nsceiver functions, which is equivalent to combining an ordinary Nano board and an NRF24LO1 module into one, which is more convenient to and small in size. The RF-NANO has exactly the same pins as the common Nano board, which is easy to nspt.

Product s:

Proceor introduction:

RF-NANO microproceor is AT328 (Nano3.0), with uSB-Micro interface, and has 14 dial input/output (6 of which can be d as PWM output), 8 og input, a 16MHz crystal oscillator, A USB-Micro port, an ICSP heaper and a reset on.

Proceor:AT328

Working voltage:5V Input voltage (recommended): 7-12V Input voltage (range): 6-20V

Dial IO pins:14 (6 of which are d as PWM outputs) (D0～D13)

og input pins:6 (A0~A5)

Io pin DC current:40mA

F Memory:32KB (2KB of which is d for bootloader)

SRAM:2KB

:1KB (AT328)

USB to serial port :CH340

Working clock:16 MHz

power supply:

RF-Nano power supply mode: Micro-USB interface power supply and external vin connected to 7~12v external DC power supply

Memory:

AT328 includes on- 32KB F, of which 2KB is d for Bootloader. Also 2KB SRAM and 1KB o

input Output:

14 dial input and output ports: The working voltage is 5V, and the output and acce limit current of each is 40mA. Each is configured with a 20-50K internal pull-up (not connected by default). In addition to this, some pins have specific functions.

Serial port signal Rx (No. o), TX (No. 1): provide the serial port receiving signal of TTL voltage level, and connect with the corresponding pin of FT232RI. External Interrupt (No. 2 and No. 3): Trier the interrupt pin, which can be set as rising edge, falling edge or both.

width modulation PWM (3, 5, 6, 9, 10, 11): Provide 6 8-bit PWM outputs.

( 10(SS), 11(MOSI), 12(MISO), 13(SCK)): communication interface.

LED (No. 13): is specially d to test the reserved interface of LED. When the output is high, the LED is turned on, otherwise, the LED is off when the output is low.

6 s of og input A0 to A5: each has a resolution of 10 bits (that is, the input has 1024 different values), the default input signal range is

0 to 5v, the upper limit of the input can be adjusted by AREF. In addition to this, some pins have specific functions.

TWI interface (SDAA4 and SCL A5): support communication interface (compatible with I2C bus).

AREF:The reference voltage of the og input signal.

Reset:Reset the when the signal is low.

Communication Interface:

Serial port: The built-in UART of AT328 can communicate with the outside through dial ports o (RX) and 1 (TX).
