RF-NANO (Arduino Nano + NRF24L01 combine)


I just bought this RF-NANO from AliExpress for S$4.79 (during sales). Basically it is an Arduino Nano (ATmega328P) combine with NRF24L01 in single board, plus built in antenna. I though great 😍, that should considerably reduce receiver weight. Unfortunately there is no unsoldered version, so I have to remove pin manually to reduce weight further. 

Everything work fine, except for the NRF24L01, it is unable to communicate 😱. I do not think is the code since I'm using the same proven working code. I suspect either the chip is broken or CE and CSN connected differently. As usual there is no information at the seller page 😨.

Luckily I found the schematic from google. Based on the schematic CE is connected to D10 and CSN is connected to D9 which is the opposite on my code. Made little modification and everything work 😁. But I will still put maybe 2 star because seller un contactable and there is no connection description on the seller page. I'm gonna break the 100% positive review 😡.


I wonder since I have transmitter which is rated for 2500 meter, will the RF_NANO able to receive signal 2500 meter away? I just need it to receive signal, that would be cool 😁. Typically NRF24L01 module with built in antenna without the external amplifier can only communicate 240 meter away.

Wire out the GPIO and receiver done, total weight 10.21 gram

Building RC Plane Under 250 grams (Part 1)

Image
Building RC plane is not easy, choosing brushless motor is already very confusing. There are so many parameter need to consider (motor size, motor weight, propeller size, battery size, etc) 😵   In the end, I asked ChatGPT 😂, I summaries ChatGPT answer on the table below. In conclusion, to be able to fly without license, I need to built something under 250 grams. Based on the table, 2212 that I bought is suitable for 300 grams and above. I bought the wrong motor, waste money 😡, should asked ChatGPT earlier, part of learning 😑. I took measurement on components that I have in hand using kitchen scale 2212 motor = 61.21 grams 30A ESC = 25.59 grams Receiver = 30.20 grams 3x servo = 31.95 grams 2x 18650 battery = 100++ grams Total 248.95 grams excluding the airframe 😭. I ask my good friend ChatGPT to recommend RC plane design with target weight of 200 grams (keep 50 grams for margin) and the answer: Wingspan: 60-80 cm (100 grams) Motor 1806 or 2204 (15-25 grams) ESC: 10A - 20A ...

Arduino Nano clone (fake FT232RL)

Image
Couple weeks ago, out of curiosity, I just bought Arduino Nano from Aliexpress. I saw it was on sale for S$1.39 (tax included). Arduino Nano with USB=C cable for S$1.39 is very-very cheap 😊, other shop sell at around S$3+ (at this time I did not know it was clone). After about 2 weeks of waiting, it is finally arrived. This thing is tiny, measured around 1.7 x 4.3 cm. Looking at the soldering are good and clean, I'm pretty happy with the product. 😊 I download the IDE 2.3.2 software from official Arduino website ( https://www.arduino.cc/en/software ). This is the time I realize it is a clone because the original Arduino Nano price at US$21.17 🤯 from the official website. With the price different, there is no way I bough the original 😂. I'm trying to share my first experience experimenting with Arduino Nano because it is not a smooth sail, although with the help of google search, I manage to overcome it😉. First of all , you need internet connection when open IDE software for...

A2212/5T 2450KV

Image
I wanted to post screen capture of the motor that I bought, just for personal note. Otherwise I most likely forgot the specification in a week time or less. There is no particular reason why I choose this motor, it just happen to see a bundle deal "Brushless motor + ESC" for S$10 😂. Many of specification mention are confusing, I have no idea what it mean 😛. After some googling: A2212/5T: 22 is the stator diameter in mm, 12 is stator height in mm. 5T is the number of turn per pole. Its the inner core size, not the outer motor size KV: RPM per Volt, 2450KV = 2450 RPM when supply with 1 Volt Max Current 12A/60S: mean can operate at 12A for maximum 60 seconds before it melt, maybe 😱 Load Current 25.2A: The maximum current the motor winding are designed to draw under specific conditions Max current = 12A/60S and load current = 25.2A, does it mean at max load the motor will burn? Why the load current is greater than max current? How do I choose battery to run this motor? Do I ne...
