Product description

2pcs Wireless Module NRF24L01+PA+LNA in Antistatic Foam Arduino Compatible with Antenna

Specifications:

The nRF24L01+ is a 2.4GHz ISM band transceiver

Range: 800+ meters line of sight

Includes on board support components and the RFX2401C which is the PA (Power Amplifier) and LNA (Low-Noise Amplifier)

A host microcontroller can communicate and configure the nRF24L01+ over a 4-pin Serial Peripheral Interface (SPI). The configuration registers are accessible through the SPI connection. Configurable parameters include frequency channel (125 selectable channels), output power, and data rate (data rates: 250kbps, 1Mbps, and 2Mbps).

The on chip voltage regulator accepts supply voltages from 1.9 to 3.6V.

The module has 5V tolerant inputs which allows for direct connection of SPI pins to the Arduino.

Internal filtering results in high margins of meeting RF regulatory standards. The module's radio uses Gaussian Frequency-Shift Keying (GFSK) modulation as well as fast Automatic Gain Control (AGC).

The module includes an Interrupt Request (IRQ) pin which can be used to wake the host microcontroller, (ex: Arduino), from sleep when the module receives a transmission providing great power conservation in battery devices.

Auto-acknowledge and auto-retransmit abilities

Weight: 13.28 g (0.468 oz)

Board dimensions, excluding pins: 15.5mm (0.61/) width x 40.7mm (1.6/) length x 12.2mm (0.48/) height

Dimensions of antenna, when angled at 90 degrees: 87mm (3.43/) height x 9.5mm (0.37/) diameter

11日,杜德偉微博曬出1992年「勁爆靚人青春大賞」的舊照。其中劉德華、鄭伊健、張智霖、莫少聰、羅文、杜德偉、梁朝偉等人難得同框。他還配文稱:「整理家中舊照片,忽然看到這張!是什麼年份呢?超過20年吧,《勁爆靚人獎》這個獎項很有趣。真的, 時間證明全都是靚人,哈哈」。

根據鳳凰網報導,照片中劉德華、鄭伊健、張智霖、莫少聰、羅文、杜德偉、梁朝偉等手持獎盃站在舞台上,各有各的帥氣。轉眼25年過去了,之前的小鮮肉現在都變成了帥大叔。

網友們紛紛評論:「都是那個年代的小鮮肉呢」、「杜德偉年輕帥氣朝氣蓬勃」、「滿滿的回憶呀!」、「這樣的同框??無法形容有多珍貴了昂!!!!PS,你吃了什麼,居然和20年輕沒什麼差別誒」、「年輕的時候也好帥呀,喜歡這個獎,最親的人」、「我要把這張照片珍藏」。

近日,一項最新的研究顯示,孩子們在考試前可吃一些藍莓,因為藍莓可以在短時間內有效地提高智力。
 

 

 

據俄羅斯衛星通訊社報導,學者們給一組孩童分發了一項任務:讓孩童的眼睛盯著電腦螢幕上的箭頭,並同時按下箭頭所指的方向。而在進行這一任務之前,數位孩童已喝下藍莓果汁,這些喝下果汁的孩童比其他孩童反應的準確率和速度高出10%。
 

從前,人們已經瞭解到,藍莓有很好的消炎和抗氧化作用,但關於藍莓可以提高智力表現水準的新研究,是第一次被發現並得到論證。
